The G2183 is a highly accurate GPS antenna—WAAS/EGNOS enabled. It is one of the first true 10 Hz GPS antennas made available. Scoring high in sensitivity, it delivers quick signal acquisition, reliable positioning, and accurate speed and course-over-ground readings. The G2183 can connect to both an NMEA 0183 device and an NMEA 2000® network, as the unit outputs both protocols simultaneously. And its compact size makes it easy to flush mount, pole mount, or rail mount. Rugged for all marine environments, the IPX6 waterproof housing can withstand virtually any condition Mother Nature throws at it.
