SI-TEX SAS-300 AIS Class B Transceiver w/External GPS Antenna

The SI-TEX SAS-300 AIS Class B Transceiver with External GPS Antenna is a complete maritime AIS system designed for vessel operators who require reliable automatic identification and positioning data across VHF marine bands. This Class B transceiver receives AIS signals from all Class A and Class B transponders within operating range, providing real-time target tracking essential for collision avoidance and maritime situational awareness in commercial fishing, recreational boating, and coastal operations.

The SAS-300 features a 6.5-inch high-resolution display with intuitive menu navigation and flexible display modes including radar-type presentation with optional chart overlay capability. The included external GPS antenna ensures accurate position fixing independent of internal systems, critical for stations operating in challenging signal environments or integrated bridge systems. At 8.2 pounds with compact 9 x 9 x 13-inch dimensions, the unit mounts easily in wheelhouse, pilothouse, or remote monitoring installations. VHF transceiver integration allows simultaneous voice communication and AIS data monitoring without channel conflicts.

This transceiver serves commercial fishing operations, harbor pilots, offshore supply vessels, and serious cruising sailors who depend on Class B AIS for regulatory compliance and operational safety. The SI-TEX SAS-300 AIS transceiver is built for continuous maritime duty where dependable target acquisition and position reporting directly impact vessel safety and crew situational awareness in busy shipping lanes and congested anchorages.

Class B AIS systems operate within established international maritime standards (ITU-R M.1371) for vessels not equipped with Class A mandatory reporting systems. The SAS-300 transmits on designated AIS channels while simultaneously receiving from all vessel transponders, enabling passive and active surveillance modes essential for bridge resource management and collision avoidance protocols.
