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 vesselís 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 as will using a splitter to run your AIS and VHF from the same antenna.
We recommend that you use a dedicated AIS antenna to ensure the best possible signal reception and transmission to maximise your safety.
