GARMIN Network Sensors GA 38 GPS/GLONASS Antenna

The GA™ 38 GPS/GLONASS Antenna provides enhanced reception of both GPS and GLONASS signals for compatible Garmin chartplotters and combos.

A robust external antenna, the GA™ 38 has a compact low-profile waterproof housing that measures 3 5/8″ x 2″ and weighs just 7.1oz. It allows three easy mounting options: pole, surface or under-deck (for the underside of fiberglass decks). 

As an external antenna, it provides GPS/GLONASS antenna installation flexibility for compatible chartplotters with a built-in GPS/GLONASS receiver. For those products with built-in antennas installed in the salon or other interior space, an externally mounted GA™ 38 can provide enhanced reception of GPS/GLONASS signals.
