AIS antenna designed to be shared with VHF radio.

Finally an antenna designed for both VHF and AIS!

This antenna is specially designed by Vesper Marine to be used with our Antenna Splitter. Up until now you've had to choose an AIS-tuned antenna that is optimized for the AIS frequencies but has lower performance for your VHF radio. Or you could choose an antenna that is designed for VHF radio communications but isn't optimal for AIS. Either of those works but we've got a better solution. an antenna that solves this dilemma. It has two key features that combine to make it ideal for use with the antenna splitter:

Wide bandwidth of over 6 MHz means it will cover 3 MHz above and below the center point

159 MHz center frequency gives excellent performance for VHF radio (156 Mhz) and AIS (162 MHz)

The result is an antenna with superior performance over other designs. It has less than 1.3:1 VSWR at 156 MHz all the way up to 162 MHz. With other VHF or AIS antennas you'll only get low VSWR at one end of the frequency band but not both.

It's perfect for installations where the lowest possible windage is a requirement.Key features:

Specially designed 1.0m stainless steel antenna

Easily replaceable stainless steel whip if it gets lost or damaged

Optimized for sharing between VHF radio and AIS transponder

Includes SO239 socket & mounting bracket

Perfect for masthead or installations where the L-bracket suits

Easily adapted to most any installation configuration

Detachable cable allows for any length to be used
