Garmin GA 38 GPS/GLONASS Antenna

The Garmin GA 38 GPS/GLONASS Antenna is a dual-constellation marine-grade positioning receiver designed for serious boaters and anglers who require reliable navigation in challenging open-water conditions. This external antenna integrates both GPS and GLONASS satellite systems, providing redundant positioning data that keeps your chartplotter locked on target even when conventional GPS alone struggles.

Engineered with a robust design, the GA 38 is built to withstand the salt spray, vibration, and temperature swings common in marine environments. Its multi-frequency receiver architecture processes signals from both American GPS and Russian GLONASS constellations simultaneously, ensuring faster acquisition and superior accuracy compared to single-system antennas. The antenna's weatherproof construction allows for clean mounting above deck without compromising your vessel's profile.

Ideal for fishing vessels, cruisers, and offshore navigation, the Garmin GA 38 integrates seamlessly with compatible Garmin chartplotters, autopilot systems, and integrated navigation suites via standard marine antenna connectors. This makes it a versatile choice for those who navigate in various conditions, ensuring you have the fix certainty and continuity you need when it matters most.
