● If possible mount the antenna at least 5m (16ft) from any RADAR or Satellite communications
antennas, and ensure the GNSS antenna is not in the beam path from any RADAR antenna.
● Route the GNSS 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 GNSS antenna cable to the GNSS connector on the AIS transceiver as shown in Figure 40.
