Unlike consumer GPS antennas tied to a specific ecosystem, the GPS 18x OEM outputs standard NMEA 0183 and RS-232 data — making it compatible with a wide range of chartplotters, autopilots, VHF radios, and third-party navigation equipment regardless of brand.\u003c\/p\u003e\u003cp\u003eWith a 5 Hz position update rate and a 1PPS (pulse-per-second) timing output, it provides accurate, low-latency position data suitable for demanding navigation and timing applications. The IPX7 waterproof rating allows mounting in exposed locations, and the wide input voltage range accommodates both 12V and 24V marine electrical systems.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOutput Protocols: NMEA 0183, RS-232, 1PPS timing\u003c\/li\u003e\n\u003cli\u003ePosition Update Rate: 5 Hz\u003c\/li\u003e\n\u003cli\u003eWaterproof Rating: IPX7\u003c\/li\u003e\n\u003cli\u003eApplication: OEM integration — autopilots, chartplotters, AIS, navigation systems\u003c\/li\u003e\n\u003cli\u003ePart Number: 010-00321-37\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The GPS 18x OEM is the right choice when you need a reliable external GPS source for a device that accepts NMEA 0183 or RS-232 input — particularly autopilots, standalone AIS transponders, radar systems, or older chartplotters that lack a built-in GPS receiver. It’s also the preferred option for mixed-brand helm setups where a single GPS sensor needs to feed position data to multiple devices from different manufacturers via an NMEA 0183 multiplexer. If your system is fully Garmin and NMEA 2000-based, the GPS 19x HVS may be a better fit. The GPS 18x OEM is the more versatile choice for integration work and non-Garmin or legacy systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation Note:\u003c\/strong\u003e Mount with a clear, unobstructed sky view away from radar domes and mast shadows.
