Radiation area of the main lobe of the RF Antenna.
Radiation area of the microwave antenna.
Other areas with inter-frequency interference or strong electromagnetic interference.
Cable Fastening Good Practices:
No more than 5m between cable fastening spaces.
No more than 1m between cable termination and first fastener.
Fastenings should be to a robust construction (i.e. mast pole, BS mount…).
Fasteners should be weather and UV resistant.
Cables should have some slack for thermal expansion/contraction between fastenings.
An 80cm, cable connects the GPS directly to the top of Air4G. When mounting the GPS antenna
remotely from the base station unit, the GPS antenna should be used in conjunction with the
Remote GPS Antenna Mounting Bracket (GPS-MNT-1) and either the 16m (CBL-GPS-TNC-16-1)
or the 40m (CBL-GPS-TNC-40-1) GPS Cable RG58 TNC-TNC by way of TNC connectors. The
cable assembly for the remote GPS antenna is shown below.
5.10.1 GPS Antenna Mounting
To mount the GPS antenna directly on the Air4G:
5. Route the RG58 cable through the flat washer and the 2 nuts (supplied).
6. Position the RG58 cable below the mounting hole on the GPS antenna mounting bracket,
as shown below:
Figure 44 - GPS cable assembly prior to mounting
7. Hand-tighten the RG58 cable TNC (90°) connector to the mating connector on the GPS
antenna.

8. Slide the flat washer up to the underside of the mounting bracket, then thread 1 nut onto
the GPS antenna threaded base and tightened.
