Description
AIS - Automatic Identification System 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 position, speed, name, course and destination of vessels. The frequency used to transmit this data is higher than marine VHF, therefore using a standard marine antenna may compromise the performance of the AIS. It is recommended that you use a dedicated AIS antenna to ensure maximum performance and safety.
