Built for Harsh Marine Environments

The MDA-6 is engineered for reliability in real-world conditions. Its IP67-rated housing protects against water, dust, and vibration, while its compact footprint allows flexible installation on any vessel.

Ideal For:

• High-speed vessels
• Commercial operators
• Recreational boaters in busy waterways
• Installations requiring long-range AIS visibility

The SI-TEX MDA-6 AIS Class B Transceiver is designed for marine vessels requiring enhanced visibility and communication capabilities. This unit utilizes 5W SOTDMA transmission, which provides increased power compared to standard Class B AIS units, allowing for earlier detection of your vessel at greater distances. It broadcasts continuous dynamic data such as Speed Over Ground (SOG), Course Over Ground (COG), heading, and hazard reports, providing surrounding vessels with an accurate understanding of your movements. The MDA-6 is suitable for high-speed vessels, commercial operators, and recreational boaters navigating busy waterways, particularly where long-range AIS visibility is critical. Connectivity options include NMEA 0183, NMEA 2000, and USB, alongside integrated Wi-Fi and Bluetooth for programming and control via tablets or laptops. Its IP67-rated housing ensures durability in harsh marine environments.
