Advanced Class B+ AIS Transceiver for Reliable Marine Navigation

The Sitex MDA-5H Class B+ SOTDMA AIS Transceiver is one of the most advanced AIS modules available, offering high-performance vessel tracking and seamless integration with marine systems. Designed for professional and recreational mariners alike, this AIS transceiver ensures superior visibility on AIS networks, even in highly congested waterways. With 5-watt transmission power, it provides extended range and priority broadcasting over traditional Class B units.

The unit is fully waterproof (IPX7 certified) and features an integrated zero-loss VHF antenna splitter, eliminating the need for a second antenna. With multiple connectivity options, including NMEA-0183, NMEA-2000, and USB, it easily interfaces with onboard navigation and communication systems. A built-in GPS & GLONASS receiver ensures accurate positioning, while dual receivers decode all DSC & AIS messages, including MOB (Man Overboard) and SART (Search and Rescue Transponder) alerts.
