Step up from standard Class B AIS transmission with the SI-TEX Hybrid Class B+ 5W AIS Transceiver. Its 5W SOTDMA transmitter, built-in 50-channel GPS receiver, and Wi-Fi connectivity give boaters a practical way to share their vessel position while viewing AIS traffic on a compatible MFD, PC, tablet, or smartphone. Need stronger AIS output without adding a dedicated display at the helm? This SI-TEX transceiver supports NMEA 2000, dual NMEA 0183 ports, USB, and 12V/24V DC installations in a compact protected enclosure.
Integration
The transceiver requires a suitable dedicated AIS/VHF antenna or approved splitter, properly programmed MMSI and vessel static data, and a compatible MFD, PC, or mobile application to view AIS targets. It is not a VHF voice radio, radar, chartplotter, emergency beacon, or collision-avoidance guarantee.
SOTDMA Class B+ equipment typically provides 5W transmit power and more predictable access to AIS time slots than standard 2W CSTDMA Class B systems. AIS target data still depends on antenna placement, VHF coverage, and other vessels transmitting accurate information. Not every vessel or navigational hazard is equipped with AIS.
Before Ordering
Confirm Class B+ AIS suitability, MMSI registration, AIS antenna or splitter requirements, GPS antenna placement, NMEA/USB/Wi-Fi display compatibility, 12V/24V power availability, and required programming support before ordering.
