Chapter 4: Antenna Installation This chapter provides information about how to install the FibeAir system antenna.

Antenna Tower Mount The following illustration shows the antenna mounting on a tower.


8/10 ft Vertical Antenna Mount

Notice

The installation, maintenance, or removal of antenna systems requires qualified, experienced personnel. Installation instructions have been written for such personnel.

Antenna systems should be inspected once a year by qualified personnel to verify proper installation, maintenance, and condition of equipment.

Ceragon disclaims any liability or responsibility for the results of improper or unsafe installation practices.

Description

Instructions given in this section apply to the mount assembly for shielded and unshielded antennas with diameters of 2.4 m (8 ft) and 3 m (10 ft).

The mount attaches to the reflector at 3 points and is offset from the center of the reflector to accomodate the feed. The mount may be offset from either side of the feed center by 200 mm (8”) and attaches to the antenna mounting pipe of the tower with 4 U-bolts. Inverting the mount position on the reflector provides the alternate offset from the feed center. The U-bolts can be loosened for coarse azimuth adjustment.

A fine azimuth strut assembly is included for adjustment of azimuth from -5° to +5°. The mount also includes an elevation assembly for adjustment of elevation from -5° to +5°.

Shielded antennas require a fixed strut and strut bracket at the rim of the reflector for greater stability. This strut is located on the opposite side of antenna center from the azimuth adjustment strut.

Tools

Standard hand tools can be used for this installation. A ratchet and deep well wrench sockets are recommended. However, combination wrenches, box or open-end type, may be used.

Wrench sizes for the furnished bolt hardware are as follows:

Wrench Size Bolt Size 10 mm M6 16-17 mm M10 18-19 mm M12 24 mm M16 30 mm M20


Split Reflector and Shield Assembly The following instructions are for the installation of 8 ft, 10 ft, and 12 ft split reflectors for parabolic antennas, and shield assembly for high performance UHX and UGX antennas.

The reflector halves and mounting ring have the same serial number.

Notice




Assembly Instructions 1. Position the crate so the halves are facing downward and the feed hole is at the top. Remove top of crate

with the mounting ring attached. Cut the bands holding the side struts and feed. Remove the side of the crate and supporting lumber to expose reflector halves. Remove the feed box and side struts.

2. Find a flat area for the reflector assembly. Set the reflector halves on the flat area and adjacent to each other. Remove the remaining items from the crate and disconnect the mounting ring from the top of the crate.

3. Station a man under reflector halves for assembly. See that the joint plates are clean, then bring the reflector halves together and align the joint plate holes. Use a drift pin for alignment. Insert all joint plate bolts except the socket head shoulder bolts. Insert all bolts from the same direction. Use a flat washer under a lock washer and nut. Do not tighten. See figure 1 below.

4. Loosely install three splice strip location bolts and nuts at the ends of the splice strips next to the center feed hole. Insert the bolts from the inside (concave side) of the reflector.

5. Add socket head shoulder bolts to the end holes of the joint plates. These must not be driven, but inserted by hand. If necessary, scrape away any paint over-spray within holes before inserting the shoulder bolts. Tighten all joint plate bolts, starting with the shoulder bolts. Add the remaining splice strip location bolts but do not tighten them.

6. The seam between reflector halves must be uniform. The person under the reflector should check each seam. If the seam is not uniform, the reflector can be forced out by hand at the center feed hole and pushed down at the middle, or as otherwise necessary (see figure 2).

When the seam is uniform, tighten several bolts at the center of the splice strips and the bolts next to the center feed hole. Work one seam at a time. The person under the reflector must hold the bolt head with a allen wrench while the nut on the outside is tightened.

After the seams are uniform, tighten the remaining splice strip bolts, starting at the center feed hole and working from strip to strip toward the rim of the reflector. Do not torque the bolts more than 8 ft-lb (10.85 N-m).


7. Add the mounting ring to the assembled reflector. Match marks are on the mounting ring and the splice strip. See figure 1. Insert 5/16" socket head bolts and flat washers from the inside and add lock washers and nuts on the outside of the reflector.

Tabs must be flush with the reflector. If not, straighten them before assembly. Do not straighten them on the reflector. When all bolts are inserted, tighten them in a clockwise or counterclockwise sequence.

8. Attach a side strut hinge to each side of the reflector. Use eight bolts, flat washers, lock washers, and nuts along the outer perimeter of the rim, and four bolts, flat washers, lock washers, and nuts along the rear of the rim to secure the hinge.

Insert bolts with flat washers through the holes in the torsion box of the reflector. Add lock washers and nuts, and tighten them.

9. For shield attachment, turn the reflector over and position it on supports.

10. Loosely assemble the transportable shield on the ground. Shield segments are match marked. Start with two bottom bolts at each shield segment overlap, and a splice bolt (or joint bracket and hardware) at the shield ring. Insert bolts and flat washers from the inside of the shield, and add flat washers, lock washers, and nuts from the outside. Do not tighten them. Loosely add the remaining bolts. See figure 3.

11. Lift shield onto reflector. Add shims and loosely add bolts, flat washers, lock washers, and nuts. Add RF gasket, remove shims, and tighten shield reflector. Tighten splice bolts, then tighten shield segment assembly bolts. Where joint brackets are provided, tighten them last.


Antenna Maintenance To ensure safe and satisfactory operation of the antenna assembly, the maintenance schedule provided in this section should be followed.

Repair damage to antennas promptly to avoid further deterioration and consequent danger to structures and personnel. Keep all installation instructions supplied with an antenna together with this maintenance schedule in a safe place for further reference. If in doubt as to what remedial action is required for damage, contact your nearest Ceragon Sales Office.

NOTICE




AFTER FIRST 3 MONTHS

1. Check for tightness of ALL antenna hardware. If any hardware is found loose or missing, replace the hardware and re-tighten per the appropriate installation instructions for the component/assembly.

2. If a planar radome is fitted check the compressed length of the radome tensioning springs, and correct if it required. Teglar radomes require the springs to be compressed to 165mm (6.5") and Hypalon to 152mm (6").

3. Check the planar radomes for damage, paying particular attention to splitting or tearing at the edge of the radome and permanent distortion or tearing near the centre of the radome. If the radome is damaged at all, then it must be replaced. If the radome shows signs of damage at the edge, then this may indicate long periods of exposure to winds at speeds close to the design limits of the antenna causing excessive flapping of the free edge of the radome. In these circumstances, consideration should be given to fitting a Teglar radome together with edge protection kit, part number series 205866. If the centre of the radome is damaged or deformed, then consideration should be given to fitting a heavy duty Teglar radome with a reinforced centre patch, and/or a radome buffer kit, part number series 132933. Where the antenna is subject to extreme winds, ensure that a J bolt retaining clip has been fitted to each J-bolt of the antenna.

The J-bolt retaining clip is designed to ensure that if the radome does tear, the radome tensioning springs and J-bolts fall from the antenna.

4. Ensure that azimuth/elevation adjusting threaded components are fully protected by Denso Paste/Tape or an equivalent product.

5. Check that there is evidence of conductive grease in the joint between the feed hub seating ring and the feed hub and in the region of the retaining circlip. Re-apply conductive grease in these areas where it is absent and over the perimeter of the hub seating ring covering the RF spring gasket.


ANNUAL INSPECTION

1. Check for tightness of ALL antenna hardware. If any hardware is found loose, replace the hardware and retighten per the appropriate installation instructions for the component/assembly.

2. Ensure that azimuth/elevation adjusting threaded components are fully protected by Denso Paste/Tape or an equivalent product.

3. Check that there is evidence of conductive grease in the joint between the feed hub seating ring and the feed hub and in the region of the retaining clip. Re-apply conductive grease in these areas where it is absent and over the perimeter of the hub seating ring covering the RF spring basket. Note: Some feeds manufactured prior to 1990 used Neoprene rf gaskets between the feed hub seating ring and the reflector which, if polluted or saline water was present, could cause corrosion of the reflector. Contact your nearest Ceragon Sales Office for appropriate replacement seating rings and RF gaskets.

4. If feed guy lines are fitted ensure that all guys have approximately equal tension with the springs lightly compressed.

5. Check the condition of the paintwork and galvanising, and touch up as required with an appropriate paint or zinc rich paint.

6. Check the antenna for any structural damage or defects. Consult Ceragon for advice if necessary, otherwise replace components.

7. If a planar radome is fitted, check the radome J-bolt spring lengths to ensure correct tension. Teglar radomes require the springs to be compressed to 165mm (6.5")m, and Hypalon to 152mm (6"). Adjust Jbolts if necessary. Check the planar radome in the same manner as at the three monthly inspection. If the radome is damaged, replace accordingly.

8. Check the reflector/shield interface for tightness of the fasteners fixing the shield to the reflector and for any signs of corrosion between the RF gasket and the shield or reflector. If corrosion is present contact your nearest Ceragon Sales Office for details of replacement gaskets.

9. If a moulded radome is fitted, check that it is correctly secured. If not, check for damage the radome securing points and replace or repair radome and hardware if necessary. In addition, if radome has suffered any other structural damage, eg due to very heavy ice fall, repair or replace radome accordingly.

10. Check that the transmission line feeding the antenna is properly supported with hangers installed in accordance with the instructions. Ensure that the connector interface between the feed and the transmission line is fully protected by Denso Paste/Tape or an equivalent product. Check the condition of the grounding kit fitted to the transmission line at the entry to the support structure, ensuring that there is a solid mechanical and electrical connection between the support structure, the grounding kit, and the transmission line. Make sure the interconnections are protected by Denso Paste/Tape or an equivalent product.


Alignment Fundamentals for the Parabolic Microwave Antenna

General Parabolic microwave antennas can be aligned using either customer supplied radio or independent path alignment transceiver set.

Microwave antennas must be accurately positioned on true azimuth and be absolutely level before beginning path alignment. Most alignment difficulties are the result of incorrect azimuth position or inadequate leveling.

Alignment Fundamentals

Azimuth Location

Azimuth position errors can result from incorrect bearing marker position or inaccurate compass reading.

True (map) bearing and Magnetic (compass) Bearing. True north on most maps is the geographic North Pole. Azimuth bearing on site maps is generally given with respect to true north. Compasses, however, point to the magnetic north pole, which is about 1,000 miles south of the geographic North Pole. See Figure 1. Unless this difference is corrected for, antenna azimuth will be incorrect.

The angular difference between true north and magnetic north is called the declination constant. Declination varies from place to place. See Figure 2.


To convert TRUE BEARING indicated on a site map, to corrected MAGNETIC BEARING read by a compass:

Add the declination constant to true bearing for sites EAST of the zero declination line (site 1 in Figure 1)

Or

Subtract the declination constant from bearing for sites WEST of the zero declination line (site 2 in Figure 1).

Declination constants are often given on site data sheets. Use Figure 2 when site declination constants are not provided.

Compass Readings and Azimuth Location

Azimuth position errors can also result from inaccurate compass reading. Magnetic compasses are not reliable near metal towers. Compass reading should be taken at lest 150 feet away from metal towers.

One method of location an azimuth marker is to first locate a point, on true azimuth, 150 feet or more from the tower (point A in Figure 3). Then locate a second point on true azimuth 150 feet away from point A, and place the azimuth marker in the ground (point B in Figure 3). The greater these distances are from the tower, the more accurate the azimuth position will be.


Leveling the Antenna

Another common alignment problem is improper of antenna and feed. The antenna and feed must be absolutely level. In rare instances, where extreme differences in elevation exist, such as in mountainous terrain or on tall buildings. the antenna will not be level. For normal variations in tower heights and ground elevations, leveling corrections should not be made unless exact differences are known.

For example, with a level antenna, beam width at 25 miles is typically many times the height of a 250 ft tower. See Figure 4. However, if the basic level position is only half a bubble width off level, as shown in Figure 5, the antenna's main beam will be shifted 2 degrees, missing the adjacent tower by a half mile.


Radiation Pattern and Signal Strength

Antenna can be verified as being on main beam by comparing measured receive signal strength with calculated net path loss.

Signal strength reading are usually measurable when at least a main beam and first side lobe are aligned. The strongest signal occurs at the center of the main beam. See Figure 6. The highest first lobe signal is typically 20-25 dB less than the main beam signal.When both antennas are aligned for maximum main beam signal strength, net path loss will typically be -50 to -65 dB. Use Figure 7 to calculate net path loss. If calculated net path loss matches the measured signal strength, both antennas are aligned on main beam.

For example typical path loss at 6 GHz for 20 mile path is 138 db. Typical antenna gain for a 10ft antenna at 6 GHz is 43 dB, or 86 dB for both antennas:

-138 dB path loss +86 dB antenna gain (2 antennas) -52 dB net path loss

If the measured signal near -52 dB, the antennas would be aligned on main beam. If the measured signal was only -80 dB, one antenna would be aligned on the first side lobe-not the main beam. If both antennas are aligned to the first side lobe, the receive signal would probably not be measurable.


Locating the Signal

When no signal can be found, perform the steps below.

As soon as signal is located, position antenna on maximum receive signal and continue with path alignment procedure.

1. (Site 1). Move antenna from left to right (±20 from azimuth marker) in search of signal. If no signal can be found, position antenna toward azimuth marker.

2. (Site 2). Repeat Step 1 (above) at site 2.

3. (Site 2). If no signal is found, position antenna toward azimuth marker. Place mark on right side strut next to side strut clamp.

4. (Site 2). Move antenna to right so mark on side strut is 4 inches from side strut clamp.

5. (Site 1). Repeat step 1 in search of signal.

6. (Site 2). If no signal is found, move antenna farther to the right so mark on side strut is 8 inches from clamp.

7. (Site 1). Repeat Step 1 in search of signal.

8. Repeat this sequence until mark on side strut has moved 16 inches either side of clamp, or until signal is located.

Locating the Main Beam

Once the measurable signal is observed, very small alignment adjustments are required to locate the main beam.

A 10 ft antenna at 6 GHz has 0.9 degrees of adjustment from center of main beam to first null. Antenna movement across the main beam will result in rapid rise and fall of signal level. Each one-sixth turn of the adjustment screw will cause a dramatic change in signal level.

First side lobe signal reading are often confused with main beam reading because the signal level at the center of the first side lobe is greater than signal level at the edges of the main beam.Figure 8 shows a typical head-on radiation view of an aligned antenna, and three typical tracking paths.


Line AA represents the tracking path of a properly antenna. The signal level as the antenna is moved from left to right is shown. The main beam is at 2, and the first side lobes at points 1 and 3.

Line BB represents a tracking path with the antenna tilted down slightly. Signal strength as antenna moves from left to right shows only the first side lobe peaks 4 and 5. Typically, this signal looks more like signal DD in Figure 9, where the first side lobe peaks are unequal due to reflections. This larger first lobe peak is often mistaken for the main beam. The correct method of locating the main beam in this case is to set the azimuth position midway between the first side lobe peaks, and then adjust elevation for maximum signal.

Line CC in Figure 8 represents a tracking path with the antenna tilted down still farther. The first side lobe signal peaks, 6 and 7, appear as one peak.

Typically, antenna misalignment occurs in both azimuth and elevation, such as position 1 in Figure 9. Moving the antenna left to right along line DD, or top to bottom along line FF would produce a signal pattern similar to DD. A common error is to track back and forth along DD, and up and down along FF, always ending up with a maximum signal at position 1.

To locate the main beam in this case, set the azimuth position of the antenna midway between first side lobe peaks 1 and 2. Then adjust elevation up and down along line GG to find the main beam peak at position 4.

The charts below show typical adjustment parameters and typical first side lobe signal levels.


Path Alignment & Cross Polarization for the Parabolic Microwave Antenna

General Aligning parabolic antennas requires a thorough understanding of alignment fundamentals. Before proceeding further with this procedure, the basic techniques described in the previous section Alignment Fundamentals for the Parabolic Microwave Antenna should be thoroughly understood.

Read this alignment procedure thoroughly before aligning antennas.

Perform each of the following steps at both antenna sites unless otherwise noted.

Parabolic microwave antennas can be aligned using either a customer supplied radio or independent path alignment transceiver set.

Path Alignment Procedure

Setting Azimuth Marker

Convert true azimuth bearing, usually given on site plan, into corrected magnetic azimuth.

Stand away from tower a distance equal to or greater than tower height (minimum 150 feet).Locate true azimuth position (magnetic azimuth corrected for declination) and set azimuth marker in ground. Care must be taken to locate azimuth marker as accurately as possible.

Test Equipment

When using customer supplied radio to measure signal strength, waveguide must be connected to antenna. Loosen all waveguide hangers within 8 feet of antenna output to prevent kinking of waveguide during adjustment.

When using independent path alignment transceiver to measure signal strength, connect transceiver to vertical polarization port at each site. Set transceiver controls according to manufacturers instructions.

Preparing the Antenna for Adjustment

Loosen setscrews on side struts and optional bottom strut. See figure 1

Loosen bolt holding the clamp assembly one turn from tight on side struts and optional bottom strut.

Loosen upper u bolts holding mount to pipe so piece of paper can just slip between mount and pipe. Excessive loosening will cause binding and retightening difficulty. Loosen lower u bolt so lock washers are free from pressure. DO NOT loosen support band on mounting pipe. Loosen two bolts at pivot point of mount frame to allow antenna to pivot in elevation.

Completely loosen fine azimuth adjustment assembly from side strut.

Position antenna to point directly toward azimuth marker on ground tighten one setscrew on one side strut.


Antenna and Feed Assembly

Loosen feed assembly mounting bolts. Place bubble level across feed horn in back of antenna to measure horizontal level. See Figure 2. Rotate feed assembly until horizontally level. Tighten feed assembly mounting bolts.


Place bubble level vertically on mounting ring of reflector. See Figure 3. Adjust elevation bolt until antenna is vertically level.

Verify that other antenna site has proceeded this far. Designate one site as site 1 and the other as site 2. Continue when both site are ready.

Setting the Azimuth And Elevation

1. (Site 1 ). Loosen set screw on side strut. Very slowly swing antenna from left to right, moving at least 20 degrees either side of azimuth marker, searching for maximum receive signal. Secure antenna at maximum signal position by tightening one setscrew 5.0, Locating Signal ( Supplement).

2. (Site 2). Repeat Step 1 at site 2.

3. (Site 1). Adjust antenna up and down in elevation, searching for maximum receive signal. Secure antenna at maximum signal position.


5. (Site 2). Tighten bolts holding collar u-brackets to tower. Lignten fine azimuth adjustment assembly to strut.

6. (Site 1). Using fine azimuth adjustment assembly. turn antenna to left until signal drops 3 dB below peak level. Turn antenna to the right, counting adjustment nut turns, until signal rises past peak, and again drops 3 dB below peak. Now move antenna to left, exactly 1/2 the counted adjustment nut turns for peak signal position.

7. (Site 1). Tighten U bolts and clamps holding antenna to pipe. U bolts must be very tight. Use socket with 18 inch handle. All gaps between mount and pipe must be taken up.

8. (Site 1 ). Adjust antenna in elevation again for maximum receive signal.


9. (Site 1 ). Lower antenna in elevation until signal drops 3 dB below peak. Raise antenna, counting adjustment nut turns, until signal rises past peak, and again drops 3 dB below peak. Now lower antenna exactly 1/2 the counted adjustment nut for peak signal position. Tighten elevation nuts firmly.

10. (Site 1). Tighten setscrews on side struts and bottom strut 1-1/2 turns beyond initial strut contact. Tighten lock nuts on setscrews.

11. (Site 1 ). Tighten bolts on mount elevation pivot points.

12. (Site 2 ). Repeat steps 5-11 at site 2.

13. Both antennas are on main beam if measured receive signal level and calculated net path loss are within customer specifications. If antennas are NOT both on main beam, refer to the section Locating the Signal (Supplement) below and adjust antennas for maximum main beam receive signal.

Cross Polarization Adjustment Cross polarization adjustment is performed after path alignment is complete. Turn radio or transceiver OFF when connecting or disconnecting from antenna.

1. (Site 1). Loosen feed assembly mounting bolts.

2. (Site 1). Set up test equipment to measure receive signal at vertical polarization port.

3. (Site 2). Set up test equipment to transmit from horizontal polarization port.

4. (Site 1). Rotate feed assembly for minimum receive signal (cross polarization null) at vertical polarization port. Record minimum cross polar signal reading for later reference. Tighten feed assembly mounting bolts.

5. (Site 1). Set up test equipment to measure signal at horizontal polarization port.

6. (Site 2 ) Set up test equipment to transmit from vertical polarization port.

7. (Site 1). Record cross polar receive signal level. The difference in signal strength between the tow recorded levels must be within 3 dB. If the difference exceeds 3 dB, rotate feed assembly slightly and repeat steps 1-7 until the measured receive signals are within 3 dB.

Diversity Antenna Alignment Alignment of diversity antenna is performed after path alignment and cross polarization adjustment is complete.

Diversity antennas are aligned with opposite site primary antenna. See Figure 4. Perform path alignment and cross polarization adjustment on diversity antennas the same as primary antennas. However, DO NOT move the primary antenna or primary feed. Adjust ONLY the diversity antenna and diversity feed.


Locating a Signal (Supplement) When no signal can be found, perform the steps indicated below. As soon as signal is located, position antenna on maximum receive signal and continue with path alignment procedure.

1. (Site 1 ). Move antenna from left to right (+20 from azimuth marker) in search of signal. If no signal can be found, position antenna toward azimuth marker.


3. (Site 2). If no signal is found, position antenna toward azimuth marker. Place mark on right side strut next to side strut clamp.

4. (Site 2). Move antenna to right so mark on side strut is 4 inches from side strut clamp.


6. (Site 2). If no signal is found, move antenna farther to the right so mark on side strut is 8 inches from clamp.


8. Repeat this sequence until mark on side strut has moved 16 inches either side of clamp, or until signal is located.

Typical Assembly


Installation

1. Verify that the new MW antenna parameters are within the designated support's application range (see below), including the specific requirements, if any, regarding Beams for Struts provision.

2. Check the engineer analysis, definition, and approval per each tower and antenna types, as issued after a particular analysis.

For a specified Beams for Struts installation, choose the correct installation position and verify that in accordance with the support's installation an adequate clearance is provided for the beams.

3. Install Lower and Upper Standoffs (1) & (2) respectively, approximately 90 cm below and above the MW installation level, using the Standard Grips (3) and the Threaded Bars (4), as follows:

- At tubular leg installation, the Grip profile cropped side should encase the leg's pipe (flanges toward the leg).

- At the angular leg installation, the Grip profile web tightens the leg's flanges.

Note: For now, only tighten the threaded bar nuts manually.

4. Install the 4" Pipe-mount (6) using the U-bolts (5) and the oval holes at the Standoff ends.

5. Confirm the Pipe-mount verticality and possible "correction" of the tower's leg taper/inclination. Use the allowable assembly flexibility provided by the oval holes, for optimal Pipe-mount positioning.

6. If the inclination tolerances of the oval holes do not satisfy the pipe-mount verticality, consider an additional adjustment by changing the vertical separation between the two standoffs.

7. When the Pipe-mount position and verticality are tuned, tighten the U-bolts and threaded bars, and install the double nuts.

8. Verify the support's verticality and firmness and install the MW antenna/gear.

9. Make all necessary provisions for the Beams for Struts assembly according to the specific directives, and in accordance with the engineer's specification.

Application Ranges

Two separate support types were designed for two ranges of MW antennas: LIGHT supports for Ø1' to Ø6' dishes and HEAVY supports for Ø6' to Ø12' dishes.

All MW dishes are Andrew models and are to be equipped with radomes.

Strut bar utilization (min.): 1 Strut for dishes of 6' diameter; 2 Struts for dishes greater than 6'.

Beams for Struts must be provided and adequately mounted at the designated points on the tower, in accordance with an engineer's specific instructions.

ANY OTHER INSTALLATION CONDITIONS REQUIRE SPECFIC VERIFICATION, AND NEED TO BE PERFORMED AND APPROVED VIA A COMPETENT ENGINEERING ANALYSIS.

The use of this kit provides an additional moisture seal for cable connections. It also prevents loosening of connections from vibration or other external stresses which would eventually allow moisture penetration. The sealed connection is suitable for typical exposed and buried cable applications.

The kit can be used for one or more connections depending on the configuration and cable type as follows:

Installation Tips

When applied, the tape must be above 32°F (0°C) to ensure adhesion. Keep tape warm by carrying in coat pockets.

Do not stretch the tape. Apply only enough tension to provide a smooth wrap.

Smooth each wrapped layer with your hands to ensure full adhesion.

Do not pull the tape to tear it - always cut it. Pulled tape eventually unravels, decreasing protection.

Add extra final layers of tape in warmer climates where there will be long exposure to damaging ultra violet (UV) rays. Two or thee extra layers of tape will provide additional UV protection.

On vertical runs, the last wrap of 3/4" tape should be wrapped from the bottom to the top. This provides a shingle effect.

When wrapping tape, overlap the tape to half-width as shown here.


Feeder Cable to Jumper Cable Connection

1. Tighten the connection with a torque wrench to the proper torque value to ensure that correct internal seals and surface contacts are made.

Torque Wrench Connector Type Torque

Andrew 244379 N 15-25 lb in

2. Prepare the cable by removing any cable markers and drying the cable and connectors. Starting at 2" (51 mm) from the feeder connector, wrap the connection with a layer of 3/4” (19-mm) plastic tape. Overlap the tape to half-width and extend the wrapping 2” (51 mm) beyond the jumper connector or plastic strain relief of a SureFlex jumper. Note: Do not remove the jumper strain relief.


3. Cut the rubber tape into three 12” (305-mm) lengths for 2-1/4" (57-mm), 1-5/8" (41-mm), and 1-1/4" (32-mm) to 1/2" (13-mm) connections.

For 7/8" (22-mm) to 1/2" (13-mm) connections, cut three 4" (102-mm) lengths of tape. Form a tapered surface by starting with two tapes that are folded to half-width and finishing with one full-width tape.

4. Cut the rubber tape into three 12” (305-mm) lengths for 2-1/4" (57-mm), 1-5/8" (41-mm), and 11/4" (32-mm) to 1/2" (13-mm) connections. For 7/8" (22mm) to 1/2" (13-mm) connections, cut three 8" (203mm) lengths of tape. For 1/2" (13-mm) to 1/2" (13-mm) connections, cut three 8" (203-mm) lengths of tape. Lay the three rubber tapes around the entire connection so that they overlap. Pull the tape as needed for overlap. Press the tapes together along the overlaps.

5. Wrap the connection with a layer of the 2” (51 mm) tape and then three continuous layers the 3/4” (19 mm) plastic tape. Overlap each tape to half-width and extend the wrapping 2” (51 mm) beyond the previous tape.


Feeder Cable to Antenna Connection

Due to the variability in design of base station antennas at the point of connector interface, special attention must be given to the application of weatherproofing materials. The following illustrations demonstrate the recommendations of Andrew Corporation in cases where there is ample access to the connection and where access is restricted.

Ample Access

1. Tighten the connection with a torque wrench to the proper torque value to ensure that correct internal seals and surface contacts are made.


Andrew 244377 7-16 DIN 8-22 lb ft


2. Wrap the connection with a layer of 3/4” (19-mm) plastic tape, starting at 1" (25 mm) from the connector or plastic strain relief of a SureFlex jumper. Overlap the tape to half-width and extend the wrapping to the flange of the antenna connector. Avoid making creases or wrinkles. Smooth the tape edges.


3. Cut an 5" (125-mm) length of rubber tape. Expand the width of the tape by stretching it so that it will wrap completely around the connector and cable. Wrap the tape around the cable connector and the cable. Press the tape edges together so that there are no gaps. Press the tape against the connection and cable. The tape should extend 1" (25 mm) beyond the plastic tape on the jumper.

4. Start wrapping a layer of 2” (50-mm) plastic tape 1" (25 mm) below the rubber tape, overlapping at half width. Finish the wrap at the flange of the antenna connector and cut the tape. Repeat this process for second layer.

5. Start wrapping three layers of 3/4” (19-mm) plastic tape 1" (25 mm) below the previous 2" (50-mm) wrap, overlapping at half width.

Restricted Access

Where access to the antenna connector and jumper cable will be restricted for taping, most of the jumper cable must be prepared before it is connected.

1. Wrap the cable and connector body with a layer of 3/4” (19-mm) plastic tape, starting at 1" (25 mm) from the connector body. Overlap the tape to half-width. Do not tape the connector clamping nut. Avoid making creases or wrinkles. Smooth the tape edges.


2. Cut a 3-1/2" (90-mm) length of rubber tape. Expand the width of the tape by stretching it so that it will wrap completely around the connector body and cable. Wrap the tape around the cable connector body and the cable. Do not tape the connector clamping nut. Press the tape edges together so that there are no gaps. Press the tape against the connector body and cable. The tape should extend 1" (25 mm) beyond the plastic tape on the jumper.

3. Start wrapping a layer of 2” (50-mm) plastic tape 1" (25 mm) beyond the rubber tape, overlapping at half width. Finish the wrap at the connector clamping nut and cut the tape. Repeat this process for a second layer.

4. Start wrapping a layer of 3/4” (19-mm) plastic tape 1" (25 mm) beyond the 2" (50-mm) tape, overlapping at half width. Finish the wrap at the connector clamping nut and cut the tape. Repeat this process for a second layer and a third layer.

5. Connect the jumper cable to the antenna connector. Tighten the connection with a torque wrench to the proper torque value to ensure that correct internal seals and surface contacts are made.



Andrew 244377 7-16 DIN 8-22 lb ft


6. Start wrapping three layers of 3/4” (19-mm) plastic tape 1" (25 mm) at the connector clamping nut, overlapping at half width. The tape should extend 1" (25 mm) beyond the cable connector clamping nut. The tape can be applied in one or more strips if necessary. A strip can be coiled onto an applicator such as a pencil. Apply only enough tension to get good adhesion and keep the tape smooth.

7. Cut a 2" (50-mm) length of rubber tape. Expand the width of the tape by stretching it so that it will wrap completely around the connector body and clamping nut. Wrap the tape around the cable connector. Press the tape edges together so that there are no gaps. Press the tape against the connector body.


8. Wrap two layers of 2" (50-mm) plastic tape and then three layers of 3/4” (19-mm) plastic tape to complete the wrapping. Start each wrap 1" (25 mm) from the previous wrap.

Note: When removing the weatherproofing from connections, take precautions to not cut through the jacket of the coaxial cable. If the jacket is cut, the rewrapping should start at the point of the exposed copper outer conductor.

Site Acceptance Checklist Notes

The following notes provide important additional information about the Site Acceptance Checklist.

1. Antenna Mounting

Mounting pole is of sufficient height to clear local obstructions, such as parapets, window cleaning gantries, and lift housings.

Mounting Pole is of sufficient height, and is safely positioned, so as not to cause a safety hazard. No person should be able to walk in front of, or look directly into the path of the microwave radio beam. Where possible, the pole should be away from the edge of the building.

Mounting pole is secure and perpendicular. A pole that is not perpendicular may cause problems during antenna alignment.

Mounting pole is grounded as per site specifications. All operators and site owners have specific requirements regarding the grounding of installations. As a minimum, typical requirements are such that any metal structure must be connected to the existing lightning protection ground of the building. Where it extends beyond the 45 degree cone of protection of existing lightning conductors, additional lightning protectors should be installed.

All steelwork is Galvanized or Stainless Steel, as appropriate to prevent corrosion.


2. Antenna

Antenna is grounded as per site specifications. See the third point in the Antenna Mounting section above.

Antenna sway braces are fitted and installed correctly, where applicable. Typically, for an antenna of 1.2 m or larger, an extra sway brace is fitted to the mounting frame of the antenna. This sway brace should not be mounted to the same pole as the antenna, but should be installed directly back to the tower or an alternative point.

Antenna Water Drain Plugs are fitted and removed, where appropriate. Some antennas have moisture drain plugs installed at various points around the antenna. The purpose of these plugs is to allow any moisture that forms on the inside of the antenna or radome to drip out and prevent a pool within the antenna. Only the plugs at the bottom of the antenna, after installation, should be removed. All other plugs should be left in position.

3. RFU (RF Unit)

The RFU is grounded as per installation instructions. See the third point in the Antenna Mounting section above.

The RFU Polarization is as per link requirements and matches the polarization of the antenna.

4. Indoor Unit

The main traffic connections are correctly terminated and crimped as per cable and connector manufacturer instructions. All fiber optic patch leads should be routed carefully and efficiently, using conduits to prevent damage to the cables.

All other user terminations are secure and correctly terminated.

All labeling is complete as per site requirements. Labeling is specific to each customer. At a site with only one installation, labeling may be unnecessary. However, at sites with multiple installations, correct and adequate labeling is essential for future maintenance operations.

Typical labeling requirements include:

Antenna labels - for link identity and bearing RFU labels - for link identity, frequency, and polarization Coax cable labels - for link identity, close to the RFU, IDU, and either end of any joint IDU labels - for link identity

2+0 XPIC Commissioning Procedure

Scope

This section describes the recommended commissioning tests for a FibeAir radio link in a 2+0 XPIC Co-Channel-Dual-Polarization configuration.


Important! Since operation of the XPIC system depends on correct installation, make sure the guidelines for XPIC system installation provided below are followed correctly.

XPIC Installation Guidelines

Antenna and RFU Installation

1. Install the dual polarization antenna and point it in the direction of the other site.

2. Install the two RFUs on a dual polarization antenna using the appropriate mounting kit, and mark the RFUs with V and H respectively.

IDU-RFU Cable Installation

1. Install two cables between the RFUs and the drawers (IDMs). Note that cable length difference should not exceed 10 meters.

2. Mark the cables with V and H respectively, and make sure V is connected to the right drawer and H is connected to the left drawer.

3. Mark the drawers respectively.

Antenna Alignment

1. Power up drawer V on both ends of the link and configure it to the desired frequency channel and maximum power.

2. Align the antennas, one at a time, until expected RSL is achieved. Make sure the achieved RSL is no more than +/-4 dB from the expected level.

Polarization Alignment

Polarization alignment is required to verify that the antenna feeds are adjusted, to ensure that the antenna XPD (Cross Polarization Discrimination) is achieved.

Polarization adjustment should be done on one antenna only.

1. Power up drawer V on both ends of the link and record the RSL reading on one end.

2. Power off drawer V on that end and power on drawer H.


3. Check the RSL obtained on this RFU on H pol, and compare it to the RSL obtained by the RFU installed on the V pol.

4. Verify that XPI (Cross Polarization Interference) is at least 25 dB

−= XPOLPOL RSLRSLXPI

5. If XPI is less than 25 dB, adjust the feed polarization by opening the polarization screw and gently rotating the feed to minimize the RSLXPOL.

Note that polarization alignment is not always possible since the RSLXPOL may fall below the sensitivity threshold of the RFU.

It is also recommended to try to maximize the XPI as much as possible, by aligning the polarization.

XPIC Commissioning Tests

Individual Link Verification

Before operating in XPIC configuration, each of the links (V and H) should be commissioned individually in order to verify its proper operation.

1 Power up only drawer V at both ends and verify its frequency channel and Tx power configuration.

2 Verify that the RSL is no more than +/-4 dB from the expected level.

3 Run BER stability test on the link for at least 15 minutes to ensure error-free operation.

4 Power up only drawer H at both ends and verify its frequency channel and Tx power configuration.

5 Verify that the RSL is no more than +/-4 dB from the expected level.

6 Run BER stability test on the link for at least 15 minutes to ensure error-free operation.

XPIC Configuration Verification

1 Using the XPIC cable, connect the two RFUs at each end to the TNC connectors. Make sure the cable is no longer than 3 meters.

2 Configure the drawers to work in XPIC mode.

3 Verify that the RSL at all four RFUs is no more than +/-4 dB from the expected level.

4 Verify that no alarms exist (if a 155 Mbps line is connected).

5 Run BER stability test on each of the 155 Mbps links for at least 1 hour to ensure error-free operation.

Note: In a 2+2 configuration, repeat each step above for each of the four coupled RFU combinations.


XPIC Recovery Verification

In order to verify XPIC operation, simulate the faults described below.

1 Disconnect the IDU-RFU cable for each of the drawers (one at a time), and verify that the other link is operating.

2 Disconnect the XPIC cable and check that the relevant alarms are generated.

3 Power down each of the drawers and verify that the other link is operating.

4 Swap the V and H cables and check that the relevant alarm is generated.

5 Mute and then un-mute one RFU at a time and verify that the other link is operating.

Note: In a 2+2 configuration, repeat each step above for each of the four coupled RFUs connected to the two standby IDUs.

2+2 Verification

Perform the tests specified in Switching Tests in the 1+1 Commissioning Procedure section earlier in this guide.

In this case, the switch will be from a main IDU connected to the main V and main H RFUs, to the secondary IDU connected to the coupled V and coupled H RFUs.
