Garmin GA38 GPS/GLONASS For Cortex V1 and M1 Black Housing
Garmin GA38 GPS/GLONASS For Cortex V1 and M1 Black Housing — Product description
Enhance Your Marine Navigation with Superior Satellite Tracking
Discover the power of dual-satellite precision with this external antenna designed specifically for demanding marine environments. By combining GPS and GLONASS signals, it locks onto more satellites for faster fixes and reliable performance, even when tree cover, buildings, or rough seas challenge standard GPS alone. Perfect for boaters who need unwavering positioning data integrated seamlessly with their VHF systems.
Its sleek, low-profile design minimizes wind resistance while the rugged build stands up to saltwater spray, vibrations, and impacts. Whether you're plotting courses offshore or navigating busy harbors, this antenna delivers the edge in accuracy and responsiveness that serious mariners demand.
Key Advantages for Boaters and Anglers
- Dual Constellation Support: Access GPS alongside GLONASS for up to 24 more satellites, boosting signal strength in obstructed or high-latitude areas.
- Marine-Tough Construction: High-impact plastic alloy with full gasketing withstands harsh conditions without compromising signal integrity.
- Flexible Integration: Tailored for VHF setups, it feeds precise location data directly to enhance AIS overlays, DSC calls, and digital selective calling features.
- Low Visibility Profile: Streamlined shape blends into your vessel's aesthetics while optimizing reception from multiple angles.
Effortless Installation Tailored to Your Vessel
Setting up is straightforward with three versatile mounting choices to suit any boat deck configuration. Opt for pole mounting on rails or masts for elevated reception, surface mount on flat areas for simplicity, or tuck it under-deck on fiberglass hulls to keep your topsides clean and unobstructed. The included 32-foot cable provides ample reach from antenna to your unit, routing easily through conduits or bulkheads.
Pro tip: Position it high and clear of metal obstructions for peak performance. Most installs take under an hour with basic tools—no specialized skills required. Regular rinse-down with fresh water keeps seals fresh and connections corrosion-free for years of service.

Frequently Asked Questions
What devices is the Garmin GA 38 antenna compatible with?
This antenna pairs perfectly with Garmin Cortex V1 and M1 VHF radios, enhancing their GPS functionality for precise location services.
Why choose an antenna with both GPS and GLONASS support?
GLONASS adds satellites from Russia's constellation, providing more options for signal acquisition. This results in quicker initial fixes, better accuracy in challenging marine conditions, and redundancy if one system faces interference.
What mounting options does it offer?
Three flexible solutions: pole mount for elevated positioning, surface mount for decks, and under-deck installation for fiberglass boats, keeping it hidden while maintaining strong reception.
Is this antenna waterproof for marine use?
Yes, it features an IPX7 rating, fully submersible up to 1 meter for 30 minutes, and gaskets seal out saltwater and moisture effectively.
How long is the included cable?
A generous 32-foot (10-meter) BNC-to-SMA cable allows flexible routing from the antenna to your Cortex unit without signal loss.
Does the black housing version differ from white?
Performance and specs are identical; the black housing offers a stealthier look that blends better with darker boat finishes.
Can it improve positioning in areas with poor GPS signal?
Absolutely—dual constellations mean more satellites visible, leading to sub-3-meter accuracy even near structures, canyons, or in northern latitudes where GPS alone may struggle.
