Installation
Page 7
In addition to the items provided with your AIS antenna splitter the following items will be required for installation:
VHF antenna
Connection to a suitable VHF antenna will be required for the AIS antenna splitter 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.
VHF radio
If you have an existing VHF voice radio connected directly to a VHF antenna, you can disconnect the VHF radio from the VHF antenna
and connect them both to the relevant connectors on the AIS antenna splitter.
AIS transceiver
If you have an existing AIS transceiver connected directly to a VHF antenna, you can disconnect the AIS transceiver from the VHF
antenna and connect them both to the relevant connectors on the AIS antenna splitter.
It is necessary to connect the VHF antenna, VHF radio and AIS transceiver for the antenna splitter to function correctly.
FM radio
The AIS antenna splitter also provides connections for the antenna of an FM broadcast radio receiver. Connection of an FM radio is
optional.
Power cable
The AIS antenna splitter is supplied with a two meter long power cable. If you require longer cables to reach your power supply please
ensure the cables are capable of carrying currents of up to 200mA on average. Means of connecting the cables together will also be
required. The use of Scotchlok
TM
connectors is recommended for this purpose.
