SI-TEX MDA-5H 5W Class B AIS Transceiver, Splitter

This SI-TEX MDA-5H, a Class B AIS unit with its antenna splitter built right in and no WiFi radio, pushes SOTDMA transmission out at a strong 5 watts, letting other boats and AIS tracking sites pick this vessel up from farther away than a standard Class B unit manages.

SOTDMA with Class A priorities keeps this vessel visible and transmitting reliably even in congested commercial harbor traffic, where a lower-priority unit can get crowded out. FCC rules mean every one of these units sold in the US must go through certified technician programming before use, and the purchase process needs the vessel's MMSI paperwork or FCC Ship Station License along with the owner's signature on the completed form.

Professional FCC-mandated programming is part of the purchase process for this unit.
