GPS Receiver - GPS Antenna

As with the base system, the rover GPS receiver requires an antenna in order to
receive satellite signals. The rover uses the same GPS Antenna Module as the base
station. Where the GPS Antenna Module is connected to the receiver depends upon
the data link being used.
If the rover system is using the UHF radio in the Communication Module, the GPS
Antenna Module attaches to the top of the UHF Antenna Module (Figure 3.20). If the
base/rover system is using the cellular modem as the data link, the GPS Antenna
Module connects directly to the Pole Adapter. The Pole Adapter is essentially an
empty UHF Antenna Module.
To attach the GPS Antenna Module to the UHF Antenna Module (or Pole Adapter),
note that the base of the GPS Antenna Module is circular except for a flattened area.
The top of either the UHF Antenna Module or the GPS Receiver Module has a
receptacle designed to hold the GPS Antenna Module. Orient the GPS Antenna
Module so that the flattened side of the Antenna Module base is lined up with the
flattened area inside the top of the receiving module and insert the GPS Antenna
Module into the antenna receptacle. If the modules are correctly aligned, the GPS
