AIS Transponder with ZeroLoss VHF Antenna Splitter

This pack includes a Class B+ 5W AIS Transponder AIT2500. It uses our latest Class B+ SOTDMA technology – this offers 2.5x transmit power of regular Class B plus a more frequent position update based on the speed of the vessel. Just like a commercial Class A transponder, SOTDMA technology also guarantees a transmission slot in areas of high AIS traffic.

It comes complete with an external GPS antenna so is suitable for mounting on all types of boat. It has both NMEA 0183 and NMEA 2000 interfaces as well as a USB PC/MAC connection. There is also a 2nd NMEA output to provide a GPS feed for a DSC VHF radio. The AIT2500 can also be fitted with a silence switch to mute transmissions.

The matching, patented, ZeroLoss SPL2000 allows the main VHF antenna to be shared with the VHF radio and with the AIT2500. You don’t need to install a 2nd VHF antenna which saves time and cost while preserving excellent performance thanks to the ZeroLoss technology. The SPL2000 also features an FM radio (boat stereo) antenna output allowing the VHF antenna to not only be utilised with the VHF and AIS but also with an on board stereo.
