3.3.3 Installing the VHF antenna
Please note the following guidelines when selecting and locating the AIS VHF
antenna:
● The VHF antenna should be located as high as possible and
positioned as far from other antennas as possible.
● The VHF antenna should have omnidirectional vertical polarization.
● Where possible the VHF antenna should be installed at least 3m
(10ft) away from other transmitting radio, satellite and radar
antennas.
● Ideally the AIS VHF antenna should be mounted directly above or
below the ship’s primary VHF radiotelephone antenna, with no
horizontal separation and with a minimum of 2m vertical separation.
Refer to Figure 9. for further guidance.
