3.1.2 VHF antenna
Connection to a suitable VHF antenna will be required for the AIS transceiver
to receive and transmit.
The standard transceiver variants will require an AIS antenna (tuned to
162MHz) for optimum performance.
Transceiver/splitter variants will require a broadband antenna (tuned to
159MHz) so it will be compatible with both VHF radio (156MHz) and AIS
(162MHz). Please take note of the warnings in section
1 regarding the use of
antennas.
3.1.3 Optional switch
A switch can be connected to the transceiver to enable and disable
'silent mode' (see section
3.2). A latching toggle switch is recommended for
this feature.
3.1.4 VHF antenna cable
Please check that the VHF antenna you intend to use has sufficient cable to
reach between the VHF antenna and the AIS transceiver unit. If it is not
sufficient you will need an extension cable. RG-58 or RG-8X can be used for
short distances, however for longer runs we would recommend a low loss
cable like RG-213. For reference the VHF antenna connector type on the AIS
transceiver unit is SO 239, and it is intended to mate with a PL 259 connector.
3.1.5 Power cable
The AIS transceiver unit is supplied with a two metre long power and data
cable. If you require a longer cable to reach your power supply, please ensure
the it is capable of carrying currents up to 2A peak / 200mA nominal for the
B92x variants, and 2.5A peak / 220mA nominal for the B95x variants. Means
of connecting the cables together will also be required, and we recommend
Scotchlok
TM
connectors for this purpose.
3.1.6 Chart plotter
Your AIS transceiver can be interfaced with a chartplotter to display other
vessels equipped with AIS. Please refer to the user manual supplied with
your chart plotter for details of how to connect and configure your chart plotter
