Garmin GA 38 GPS/GLONASS Antenna
The Garmin GA 38 is a compact external antenna that receives both GPS and GLONASS satellite signals, giving compatible Garmin chartplotters and VHF radios access to a larger combined satellite constellation for faster acquisition and more reliable positioning — especially in challenging environments where signal obstructions can affect single-system receivers.
Key Features
- Dual-system reception — tracks both GPS and GLONASS satellites simultaneously
- Larger satellite constellation improves acquisition speed and position reliability
- Compact, low-profile housing for unobtrusive mounting on deck, arch, or cabin top
- Weatherproof construction rated for continuous marine exposure
- Compatible with Garmin chartplotters and VHF radios that support an external GPS/GLONASS antenna input
- Part No. 010-12017-00
Parts Desk Insights
Best Use Case: Ideal for vessels where the chartplotter or VHF radio is mounted below decks, inside a pilothouse, or in a location with limited sky visibility that reduces internal GPS performance. The dual GPS/GLONASS capability is particularly beneficial in high-latitude cruising areas — such as the BC coast, Alaska, and the Pacific Northwest — where GLONASS satellite geometry can significantly improve fix reliability. Confirm connector type and cable length requirements, and verify compatibility with your specific Garmin device before ordering.
