We bought an em-trak B954 5W SOTDMA Class B AIS transponder with integrated Wi-Fi and Bluetooth for mobile device connectivity. It has an internal VHF antenna splitter to enable sharing of a single existing VHF antenna without performance loss. Works with NMEA networks. Contain next-gen GPS receiver and internal antenna. Ultra-low power consumption. It requires an MMSI and must be programmed by a qualified technician.
