What is the Marine Automatic Identification System?


  • The Marine Automatic Identification (AIS) System, is a Very High Frequency (VHF) radio broadcasting system that transfers packets of data over the VHF data link (VDL) and enables AIS equipped vessels and shore-based stations to send and receive identification information that can be displayed on an electronic chart, computer display or compatible radar

  • The AIS Class A system is mandatory for vessels over 300 gross tonnage, whereas Class B has been developed for vessels such as work craft and pleasure craft with limited functionality

  • All components used are of the highest quality to ensure long term survival in the harsh marine environment

  • These antennas will deliver reliable performance for many years

  • The MM1 folding deck mount is supplied as standard and is constructed from toughened plastic

  • This base folds down in two directions and also swivels in the opposite plane by loosening the stainless steel pivot bolt. This versatility allows the antenna to be mounted in a variety of positions on any flat surface and at any angle using four screws or bolts.
