AIS Automatic Identification System Marine VHF Deck Mount Antenna, Model CM162AIS

CM162AIS is a marine deck mount antenna factory tuned for the AIS Automatic Identification System operating in the VHF frequency range 161.9 to 162.1 MHz.

The single piece white fibreglass radome stands 1.4 metres tall and the antenna delivers 2.1 dBi gain. 300 mm of white RG58 low loss cable side exits from the folding deck mount base and an N-Type Female connector is fitted to the cable for easy installation.

The marine AIS Automatic Identification 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.

This information can help in situational awareness and provide a means to assist in collision avoidance. AIS can be used as an aid to navigation by providing location and additional information on buoys and lights.

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.

This deck mount antenna is factory tuned to operate with both AIS Class A and Class B systems. There are two models to choose from.

• CM162AIS is the standard model with white delrin ferrule and MM1 folding deck mount 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.
• CM162AIS-SS has a chromed brass ferrule and the MM2 stainless steel folding deck mount base for those who prefer the ultimate in quality, durability and strength.

Feeder cable, connectors, cable ties and tape are available separately to complete the installation.
