VHF antenna & splitters

The AIS system operates on 2 channels of VHF frequencies and to receive and transmit AIS information it is necessary for an AIS unit to be connected to a VHF antenna.

One option is to fit an antenna splitter such as our SPL2000, which allows VHF radio and AIS to use the main VHF antenna. The other option is to install another VHF antenna which will only be connected to the AIS.

Any VHF antenna can be used, although some antennas are tuned to AIS frequencies to give you better range.
