Installation and configuration
Page 25
● The VHF antenna cable should be kept as short as possible to
minimize signal loss. High quality, low loss co-axial cable appropriate
to the installation location should be used.
● The VHF antenna cable should be terminated in a PL-259 co-axial
connector for connection to the AIS transceiver.
● Any outdoor installed connectors in the antenna cables should be
waterproof by design.
● Antenna cables should be installed in separate signal cable channels
at least 10cm (4ins) away from power supply cables. Crossing of
cables should be done at right angles and sharp bends in the
antenna cables should be avoided.
● It is recommended that a suitable surge arrestor is fitted in-line with
the VHF antenna connector.
Connect the VHF antenna cable to the VHF connector on the AIS transceiver
as shown in Figure 10.
