AIS Class B Antenna splitter

The Class B antenna splitter will make installation much easier as well as save cost for an additional antenna, since it is normally not possible to have two VHF antennas in the top of a mast on a sailboat. The Class B antenna splitter solves the problem and you can optimize the coverage on all your VHF radio equipment by being able to put the antenna at the highest position for all the equipments. The Class B antenna splitter is the first to work with two active units like a VHF and AIS Transponder.


The True Heading Class B VHF Antenna splitter makes it possible to:


  • Use a single VHF antenna installation for both your VHF and the AIS-CTRX Class B Transponder.
  • Reduce and save on installation cost and time.
  • Improve coverage since you can have the antenna at the highest position for both AIS and VHF.
  • Have a failsafe operation with priority to VHF voice radio operation even in case of failure of the splitter power supply.
  • Use VHF, AIS and FM with the same antenna and no additional filters.
  • Simply show status with LED indicators
