Standard Horizon GX1850 Fixed Mount VHF – NMEA 2000 – Black – GX1850B

Description

Standard Horizon GX1850B 25W Fixed-Mount VHF Marine Radio – Black

The Standard Horizon GX1850B is a 25 watt Class D fixed-mount marine VHF radio built for dependable communication, safety, and seamless integration with modern marine electronics. Designed for use on cruisers, sailboats, fishing boats, and commercial vessels, this black-finished VHF transceiver offers reliable performance with advanced features and network connectivity. 

Equipped with Class D DSC (Digital Selective Calling) and a dedicated CH70 receiver, the GX1850B enhances safety by allowing continuous monitoring of the distress channel while operating on other channels. Its ultra-slim, compact chassis (approx. 3.3″ rear depth) enables flexible installation options — including flush or bracket mounting — in tight dash spaces. 

The radio supports both NMEA 2000 and NMEA 0183 connectivity, making it easy to share radio data and DSC alerts with compatible chartplotters, GPS units, and multifunction displays. While an external GPS source is required for position reporting with DSC, NMEA-enabled systems allow you to integrate the GX1850B into your vessel’s electronics network. 

Additional user-friendly features include an E2O Easy-to-Operate menu system, programmable priority scan and multi-watch, NOAA weather channels with alerts, and support for optional second-station remote microphones with intercom capability. 

Key Performance Features

• NMEA 2000 Interface: True “Plug-and-Play” networking. Easily bridge your radio with your GPS/Chartplotter to share position data and AIS (when connected to compatible sources).

• Shallow-Mount Case: Ideal for the restricted space found in modern center consoles and RIBs.

• E2O (Easy to Operate) Menu: Uses a simplified, icon-driven interface that makes navigating advanced settings intuitive and fast.

• Second Station Capable: Connect an optional RAM4 (SSM-70H) remote mic to control all VHF and DSC functions from the flybridge, tower, or cockpit.

• Advanced Scanning: Features Programmable Scan, Priority Scan, and Dual Watch to keep you updated on all relevant traffic.

• IPX8 Submersible: Industry-leading waterproof rating (1.5 meters for 30 minutes), ensuring reliability in open cockpits.

Are you planning to flush mount this radio into your dash?

Since the GX1850B is so shallow, it is one of the easiest radios to flush mount. I can provide the exact cutout dimensions or help you find a NMEA 2000 starter kit if you’re building a new network. Would you like that information?
