Antennas and Splitters

Vesper Marine manufactures a unique AIS VHF splitter which we designed to enhance the performance and increase the reception range of our AISWatchMate and XB products. By providing signal gain it greatly increases the reception range and includes a variety of troubleshooting LED indicators to assist with installation and ensure maximum performance from your AIS transponder.

Our GPS antennas are designed specifically to match our WatchMate 850 and WatchMate Vision transponders. These antennas have powerful low noise amplifiers and provide exceptional GPS performance. They feature flexible mounting options and come complete with cables that plug right into the transponder.
