GPS 19x NMEA 0183Installation Instructions CAutIoNAlways wear safety goggles, ear protection, and adust mask when drilling, cutting, or sanding.NoticeWhen drilling or cutting, always check what is on theopposite side of the surface.The Garmin GPS 19x NMEA 0183 HVS high-sensitivity GPS antenna provides position informationover NMEA 0183. The GPS 19x NMEA 0183 HVScan be connected to a Garmin chartplotter or anotherNMEA 0183-compliant device.The antenna must be properly installed accordingto these instructions. You need the appropriatefasteners, tools, and mounts listed in each section.These items are available at most marine dealers.NotE: When connecting this antenna to a GPSMAP2000, 3000, 4000, or 5000 series device, you mustlimit the update rate. If the update rate is not limited,the chartplotter might not receive and display theGPS signal properly.Registering the Device• Keep the original sales receipt, or a photocopy, ina safe place.For future reference, write the serial numberassigned to your antenna in the space provided. It islocated on a sticker on the back of the antenna.Serial numbertools Needed• Drill• 1/8 in. (3.2 mm) drill bit• 3/4 in. (19 mm) drill bit for a pole-mount cable-hole• 1 in. (25 mm) hole saw for a surface-mount cable-hole• Screwdriver, appropriate for the screw type• Countersink bit for mounting on fiberglass• Marine sealant for some mounting options• Solder and shrink wrap◦ Needed for all wiring connections◦ Specifically needed when limiting the antennato 1 Hzoptional Accessories• Screws, for under-deck mountingMounting type and LocationConsiderationsYou can mount the antenna on a flat surface,attach it to a standard 1 in. OD, 14 threads per in.,pipe-threaded pole (not included), or install it underfiberglass.For optimal performance, consider these guidelineswhen selecting the antenna mounting location.• The antenna must be mounted 5.9 in. (150 mm)from a compass to avoid interference.• To ensure the best reception, the antennashould be mounted in a location that has a clear,unobstructed view of the sky in all directions ➊.➊ ➌➋• The antenna should not be mounted where it isshaded by the superstructure of the boat ➋, aradome antenna, or the mast.• The antenna should not be mounted near theengine or other sources of ElectromagneticInterference (EMI) ➌.• If a radar is present, it is best to install theantenna above the path of the radar ➍, though itis acceptable to install it below the path of theradar ➎ if necessary. The antenna should not beinstalled directly in the path of the radar ➏.➏➎➍• The antenna should be mounted at least 3 ft.(1 m) away from (preferably above) the path of aradar beam or a VHF radio antenna ➐.➐• On a sailboat, to prevent inaccurate speedreadings caused by excessive heeling, theantenna should not be mounted high on themast.• The antenna provides more-stable readingswhen located nearer to water level.testing the Mounting Location1 Temporarily secure the antenna in the preferredmounting location and test it for correct operation.2 If you experience interference with otherelectronics, move the antenna to a differentlocation, and test it again.3 Repeat steps 1–2 until you can verify that theantenna operates correctly.4 Permanently mount the antenna.Surface-Mounting the AntennaBefore you permanently mount the antenna, testthe mounting location for correct operation.Use the surface-mount bracket ➊ as your mountingtemplate.➊➋➌➍➎
