The Garmin GA 38 is a dual-system external antenna that locks onto both GPS and GLONASS satellites, delivering stronger, more consistent positioning for compatible chartplotters and marine electronics. Its low-profile, IPX7-waterproof housing handles the elements, while three included mounting options — pole, surface, and under-deck (fiberglass decks) — give you the flexibility to position it where signal reception is best on virtually any vessel.
