ZCG Scalar CM162AIS marine deck-mount antenna

The ZCG Scalar CM162AIS marine deck-mount antenna is factory-tuned for the automatic identification system (AIS) that operates in the VHF frequency range of 161.9 to 162.1 MHz.

A single 1.4 m white fibreglass radome antenna delivers 2.1 dBi gain while 300 mm of white RG58 low loss cable that exits from the ferrule is fitted with an n-type male connector, allowing for easy installation.

The marine AIS VHF radio broadcast system transfers packet data via a VHF data link, enabling AIS-equipped vessels to connect with shore-based stations and send and receive identification information. This can be displayed on an electronic chart, computer display or compatible radar - improving situational awareness and assisting in collision avoidance. It can also be used to aid navigation by giving location information as well as providing information on buoys and lights.

The AIS Class A is mandatory for vessels over 300 gross tonnage while the Class B has been developed for work- and pleasure-craft and has limited functionality.

The antenna is tuned to operate both with both Class A and B systems and there are two models to choose from, depending on the vessel’s requirements.

The CM162AIS is the standard model with a white delrin ferrule and the MM1 folding deck mount is constructed from toughened plastic. The base folds down in two directions and also swivels in the opposite plane by loosening the stainless steel pivot bolt. This allows the antenna to be mounted in a variety of positions on any flat surface and at any angle.

The CM162AIS-SS is said to have greater durability and strength with a chromed brass ferrule and an MM2 stainless folding desk mount.
