The Garmin 19x is a next-generation GPS antenna (available in two models: HVS—compatible with NMEA 0183—and NMEA 2000) that provides users with up to 10-hertz update rates for position, velocity, and time data. Using high-sensitivity reception, the 32-channel antennas deliver accurate data to Garmin autopilots, chartplotters, and marine instruments.
The antennas track multiple satellites from various systems including the U.S. Global Positioning System, and with a software update, the Russian GLONASS system, Japan’s Quasi-Zenith Satellite System (QZSS), and the European Galileo system. Using satellite data from additional systems allows the 19x antenna to provide super-accurate position fixes. The WAAS-enabled 19x antennas provide fixes to within 10 feet. And because it reports data ten times as often as some GPS antennas, the 19x helps Garmin devices display smooth and accurate heading information.
The 19x can be pole- or flush-mounted or installed on the underside of a fiberglass deck. Its durable plastic dome measures 3 19/32 inches in diameter and 1 15/16 inches tall and is built to the IPX7 waterproof standard, which means it can be immersed in water to 1 meter of depth for up to 30 minutes.
