Standard Horizon GX2400B Black VHF/AIS Marine Radio with Integrated GPS, NMEA 2000 & 30W Hailer – Fixed Mount
The Standard Horizon GX2400B is a professional-grade fixed-mount marine VHF radio built for serious boaters, cruisers, and commercial operators who need communication, navigation, and safety awareness in one powerful unit. This black-finished model integrates AIS target reception, a built-in GPS receiver, full NMEA 2000 networking, and a 30-watt loud hailer/PA system to deliver unmatched performance on coastal, offshore, and blue-water passages.
With an integrated AIS receiver and display, the GX2400B shows nearby vessel information — including MMSI, call sign, ship name, bearing, distance, speed over ground (SOG), and course over ground (COG) — directly on the large front-panel screen. This helps you track traffic around your vessel and alerts you when other AIS targets are approaching too close.
The unit combines Class D Digital Selective Calling (DSC) with a dedicated Channel 70 receiver, ensuring continuous monitoring of distress and safety channels while you operate on other channels. Its built-in 66-channel GPS receiver provides navigation data such as GPS compass, waypoint navigation, latitude/longitude, and navigation status in real time.
A powerful 30 W public address/loud hailer system with programmed fog signals and listen-back capability enhances onboard communication. The last selected VHF channel can still be monitored while in hailer mode, and the included voice scrambler allows secure private communication when paired with compatible Scrambler-equipped radios.
Designed for easy integration into modern boat electronics networks, the GX2400B supports NMEA 2000 and NMEA 0183 connectivity to share AIS, GPS, DSC, and radio data with chartplotters and multifunction displays. It also features noise-canceling audio, intercom support for second stations, programmable scan modes, MOB (Man Overboard) functionality, NOAA weather channels with alerts, and a bright night-mode display — all wrapped in a rugged, marine-ready design.
Key Performance Features
-
Integrated AIS Receiver: Monitors Class A and B vessels. You can initiate a DSC call directly to an AIS target without manually typing in an MMSI number.
-
NMEA 2000 & 0183 Connectivity: Plug-and-play compatible with Garmin, Raymarine, Simrad, and Lowrance networks. It shares GPS and AIS data across your entire system.
-
30W Loud Hailer with Listen Back: Includes a built-in 30W PA system with pre-programmed fog signals. The "Listen Back" feature uses the hailer horn as a microphone to hear responses from the deck or other boats.
-
Built-in 66-Channel GPS: The internal antenna is located in the front face; however, the radio can also use GPS data from your NMEA 2000 network for redundancy.
-
Second Station Capability: Support for the wired RAM4 (SSM-70H) or wireless RAM4W (requires SCU-30 access point) to control all radio and AIS functions from the flybridge or cockpit.
-
Voice Scrambler: Includes a built-in 32-code voice scrambler for private communications.

Will you be connecting this to a Loud Hailer horn?
To use the 30W Hailer and Fog Horn functions, you’ll need an external 4-ohm or 8-ohm horn (like the Standard Horizon 220SW). Would you like me to find the specs for a compatible hailer horn?
