6. Connect the RG58 cable attached to the GPS to the Lightning/Surge protector (required)
which is connected to the TNC to TNC cable to the GPS connection on the bottom
Air4Gp.
Note: Affix cable to the BS to avoid strain on the connections.
7. Verify that the weatherproof cable is in the proper position and hand tighten the cable
(using no tools), to prevent water leakage. Apply self-amalgamating insulating tape on all
critical connections.
4.6.2 Remote Mounting of GPS Antenna
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.
Note: Care should be taken so that the remote installation of the GPS antenna
should be distanced from any obstructions that can interfere with “clear sky”
conditions.
