ANTENNA LINECoax Cable Grounding Kit positions

2

In a tower and equipment room there are 3 coax grounding points with a optional fourth one:

1 At the highpoint of installed antenna under the antenna to the

Coax Cable Grounding Kit positions

1. At the highpoint of installed antenna under the antenna to the closest tower grounding bar (TGB) following a downward path

2. At the bottom of the tower TGB before the cable turns from vertical to horizontal.

3. A lightning arrestor at the MGB at the entry to the shelter (entry gland MGB)

4 In case of vertical cable length of more than 30meters an 1 TGB4. In case of vertical cable length of more than 30meters an additional coax grounding point is optional to be installed above the center tower TGB.

5. Each radio unit will have a separate grounding cable directly to the closest TGB under it. This can be done directly to the tower TGB or to a sub TGB next to the antenna mounting.
