VHF and FM from one antenna: Simplify Class B AIS installation by using a single VHF antenna to combine AIS and VHF operations, saving both time and money and making installation quick and easy.

The S100s core technology enables it with superior performance which translates into zero performance loss for the connected devices.Use your existing VHF antenna: The S100 is an ideal complement to a good quality Class B or receive-only AIS where there is an existing VHF antenna available that is currently used for your VHF radio.SpecificationsDimensions: 4 3/4" x 3 1/8" x 2"Voltage: 12/24V DC Amperage: Less than 150mA continuous @ 12VConnectors: SO-239 sockets for VHF antenna and radio connections.
