Sitex SAS-300 Class B AIS With External GPS Antenna

The Sitex SAS-300 Class B AIS with External GPS Antenna is a professional-grade marine navigation and automatic identification system designed for vessels requiring reliable, real-time vessel tracking and collision avoidance. This Class B transponder serves commercial fishing fleets, workboats, law enforcement marine units, and tactical maritime operations where situational awareness and compliance with international maritime regulations are non-negotiable. The external GPS antenna integration delivers precise positioning data essential for accurate vessel identification and tracking across busy waterways and coastal operations.

Built to marine-grade standards, the SAS-300 combines dual-channel VHF technology with integrated GPS positioning to broadcast vessel identity, location, course, and speed to nearby traffic and shore-based monitoring stations. The external GPS antenna configuration ensures unobstructed satellite acquisition, critical for maintaining continuous positional updates in challenging electromagnetic environments common aboard steel-hulled vessels and in areas with RF interference. Weighing 7.05 pounds with a compact footprint, the unit delivers reliable AIS transmission across international maritime frequencies while maintaining Class B compliance standards that balance power output with vessel size requirements.

Law enforcement marine patrol units, Coast Guard auxiliary personnel, and commercial maritime operators benefit from the SAS-300's dependable identification capability and integrated navigation data. Installation requires standard 12-24VDC power supply and antenna mounting on the vessel's highest structural point to maximize transmission range and GPS signal reception. The unit integrates seamlessly with existing marine electronics via NMEA protocol output, enabling chart plotter connectivity and vessel monitoring system integration for comprehensive maritime situational awareness.
