The Standard Horizon GX1800GB is a high-performance 25 W fixed-mount marine VHF radio with built-in GPS, designed for reliable communication and enhanced safety on recreational and commercial vessels. This Black Explorer-Series transceiver combines essential marine radio features with integrated GPS position awareness — helping you stay connected and informed on the water.
Featuring a 66-channel WAAS GPS receiver built into the front panel, the GX1800GB eliminates the need for an external GPS antenna, enabling DSC position reporting, navigation data, and waypoint tracking directly from the unit. The radio also includes a separate CH70 receiver, allowing continuous monitoring of distress calls while you’re operating on other channels.
The radio’s ultra-slim rear case design (approx. 3.3″ depth) makes installation easier in tight dash spaces and supports flush or bracket mounting. Standard Horizon’s intuitive E2O Easy-to-Operate icon and menu system simplifies feature access, including programmable scan modes, priority scan, and multi-watch functions. You can also connect an optional second-station remote microphone (such as RAM4 SSM-70H) and use the built-in intercom feature to communicate between stations on board.
Key onboard navigation features include GPS compass display, waypoint entry and navigation, position display of latitude/longitude, speed over ground (SOG) and course over ground (COG), and automatic DSC position polling of multiple vessels. The unit also supports NOAA weather channels with alerts and selectable night-mode display for low-light conditions.
Built-in 66-Channel GPS: The internal antenna is located in the front face of the radio, providing immediate position data for DSC distress calls and waypoint navigation.
Class D DSC: Features a dedicated receiver for Channel 70, ensuring you receive distress alerts even while communicating on other channels.
Large Dot Matrix Display: A high-resolution, backlit screen that is easy to read in direct sunlight or at night (with a selectable Night Mode).
RAM4 Second Station Capable: Can be expanded with an optional SSM-70H (RAM4) remote mic, allowing you to control the radio and use the intercom from a different location on the boat.
E2O (Easy to Operate) Menu: An intuitive icon-based menu system that simplifies programming and daily use.
NMEA 0183 Connectivity: Allows you to share GPS position or DSC information with older chartplotters and instruments.

Are you planning to install this on an open center console?
Since the GPS antenna is built into the face of the radio, it works best when it has a clear view of the sky. If you're mounting it under a thick hardtop or inside a metal cabin, you might need the SCU-38 External GPS Antenna to maintain a signal.
The Standard Horizon GX1800GB Fixed Mount VHF with GPS – Black is an excellent choice for boaters seeking trusted VHF communication with built-in GPS navigation and advanced usability features for coastal, inland, and offshore use.
