Simrad RS40 VHF AIS-RX

The Simrad RS40 VHF AIS-RX is a professional-grade marine communication receiver purpose-built for serious anglers, commercial operators, and recreational boaters who demand real-time vessel tracking and situational awareness on the water. After years on the water, any skipper knows that knowing what's happening around you—especially in busy shipping lanes or crowded fishing grounds—is the difference between a safe day and a dangerous one. This dual-purpose receiver combines VHF radio capability with AIS (Automatic Identification System) receive functionality, giving you instant access to vessel positions, course, speed, and identification data from other maritime traffic in your area.

The Simrad RS40 operates on the international VHF marine band while simultaneously receiving AIS signals on the dedicated 162 MHz frequencies, allowing you to monitor distress calls and safety broadcasts without interference from ship tracking data. The receive-only AIS architecture means the unit passively collects vessel information—no transmission required—making it ideal for vessels that need awareness without broadcasting their own position. With a compact 5.3-pound profile, this receiver integrates easily into existing pilothouse or console setups without demanding premium real estate. The rugged marine-grade construction withstands salt spray, vibration, and the demanding thermal cycles typical of open-water operation.

Commercial fishermen, charter boat operators, and blue-water cruisers benefit most from this setup, particularly in congested waterways where collision avoidance is critical. The AIS-RX capability pairs seamlessly with compatible Simrad chartplotters and multifunction displays, consolidating traffic overlay directly onto your chart view so you can navigate with confidence. Installation requires connection to a standard marine antenna system and 12/24 VDC power, making retrofit straightforward on most vessels. Whether you're running offshore, navigating shipping channels, or simply want enhanced maritime situational awareness, the Simrad RS40 VHF AIS-RX delivers the professional-grade communication tools that serious boaters rely on.
