●
The GPS antenna should be mounted as high as possible, however it is not recommend the antenna
is mounted on a top of a high mast where the motion of the vessel will cause the antenna to swing
and potentially reduce the accuracy of the GPS position. See Figure 39 for guidance.
●
If possible mount the antenna at least 5m (16ft) from any RADAR or Satellite communications
antennas, and ensure the GPS antenna is not in the beam path from any RADAR antenna.
●
Route the GPS antenna cable through the pole mount and then to the AIS transceiver. If extension
cables are required all junctions should be made using appropriate co-axial connectors and made
watertight.
●
Connect the GPS antenna cable to the GPS connector on the AIS transceiver as shown in Figure 40.
