Grounding and high This antenna, which is approved by thevoltage protection: Deutsche Bahn AG, is D.C. grounded to protect

against lightning and high-tension lines.

Accessories: Low-noise GPS-preamplifier 742 185(please order separately).

Warning: If the antenna is operated without the preampli-fier type no. 742 185, please note the followingpoints.

Due to the fact that the inner conductor of theGPS antenna is DC grounded, the input of theGPS receiver is loaded with a DC short circuit.If the GPS receiver provides a remote DCpower supply, this could damage the GPSreceiver.

At the GPS input of the antenna a level of 28 dB below the applied GSM signal

appears. Depending on the level of the GSMsignal, the GPS receiver may be overloadedor damaged.

Low Noise Amplifier GPS742 185

Additional features:The maximum input power at the input of the amplifier atGSM 900 is limited to +12 dBm.The noise level at the GPS-frequency generated by theGSM 900 operation should not exceed the thermal noiselevel at the input of the GPS-amplifier, otherwise the noisefigure will be increased.

The low noise amplifier 742 185 is designed for the use with the dual band GSM 900 / GPStrain antenna type no. 741 806. The low noise amplifier includes a preselsection filter to pre-vent the interference in case of simultaneous operation at GSM 900 and GPS.
