AIS/VHF/FM Antenna Splitter

At last An Antenna Splitter with Gain Not Loss

Many AIS splitters introduce significant signal loss, some say no loss but this unique Vesper Marine splitter is the only one that provides signal gain - improving AIS reception and increasing range. This is because the Vesper Marine splitter has a built-in low noise amplifier. This is especially important to increase the receive range from the increasing number of low power AIS SART and MOB devices.

In addition to the amplification provided by this splitter, when used with your existing antenna you can optimize the range of your AIS transponder because the antenna is also mounted as high as possible.

Designed to work with any AIS receiver or transponder* with unique integration features for the AISWatchMate 850 and WatchMate Vision AIS transponders.

To simplify installation you can share an existing VHF antenna by using this splitter. The unit removes the need for a separate VHF antenna for an AIS receiver or transponder and allows a single antenna to be shared with a VHF radio.

This is an excellent solution when it is difficult to install an additional antenna or you wish to share an existing VHF antenna and maximize your AIS range.

This Vesper Marine splitter is specifically designed for use with both AIS receivers and transponders.

You can use this splitter with an existing antenna installation that is in good operating condition. However, for an optimized AIS and VHF antenna system, choose our AIS antenna designed to be shared with VHF radios.

Note: The splitter includes one 2M (6.5') long patch cable to go between the splitter and your VHF radio. You will need an additional appropriate length 50 ohm cable with standard PL259 plugs to go between the splitter and your AIS transponder or receiver. This should be ordered separately based on the required length. See the related products list for popular options.

* See the specifications page for info about using the Vesper Marine splitter with other manufacturers AIS transponders.
