In addition to the items provided with your AIS receiver the following
items will be required for installation:
VHF antenna
Connection to a suitable VHF antenna will be required for the AIS
receiver to operate. A standard marine band VHF antenna such as
that used with VHF voice radios will be sufficient. Please take note
of the warnings in section 1 regarding the use of antennas.
Alternatively, if you wish to use an existing VHF antenna, antenna
splitter products are available which allow the existing antenna to be
used with two radio devices, such as a VHF voice radio and the AIS
receiver.
Antenna cables
Please check that the VHF antenna you intend to use has sufficient
cable to reach between the VHF antenna and the AIS receiver unit.
If it is not sufficient you will need an extension cable. Please contact
your dealer for details of suitable products. For reference the VHF
antenna connector type on the AIS receiver unit is SO239, and is
intended to mate with a PL259 connector.
Power and data cables
The AIS receiver unit is supplied with a one metre long power and
data cable as an integral part of the AIS receiver unit. If you require
longer cables to reach your power supply, please ensure the cables
are capable of carrying an average current of up to 200mA. Means
of connecting the cables together will also be required. The use of
TM
Scotchlok
connectors is recommended for this purpose.
