Seamaster AIS Antennas

AIS is a marine tracking system used for identifying and locating vessels by electronically exchanging data with nearby ships. The AIS unit uses a standardised transceiver to broadcast the vessel's position and name as well as speed, course and destination. The frequencies used to transmit this data are higher than marine VHF, so using a standard marine VHF antenna will compromise the performance of the AIS system.  We recommend that you use a dedicated AIS antenna to ensure the best possible signal reception to maximise your safety.
