Description
The Garmin GA 38 is a robust external GPS and GLONASS antenna designed to provide reliable satellite reception for compatible Garmin marine equipment. Its low-profile, waterproof housing is ideal for exposed marine installations and provides greater flexibility when the connected device’s internal antenna does not have a clear view of the sky.
The antenna supports three installation options: pole mounting, surface mounting or under-deck mounting beneath a fibreglass deck. A 10-metre antenna cable with BNC connector is included for convenient installation around the vessel.
