Installing the GPS Antenna
To install the GPS 17x antenna, select a suitable location, mount the antenna, and connect the antenna to power and to your GPSMAP 3000
series chartplotter.
Mount the GPS 17x Antenna
You can surface mount the GPS 17x antenna, attach it to a standard 1 in. OD pipe-threaded-pole marine mount (14 threads-per-inch—not
included), or even install the antenna under fiberglass.
Select a suitable location for the GPS 17x antenna on your boat. To ensure the best reception, mount the GPS 17x antenna in a location that has
a clear, unobstructed view of the sky in all directions.
Avoid mounting the GPS 17x antenna where it is shaded by the superstructure of the boat, a radome antenna, or mast.
On a sailboat, avoid mounting the GPS 17x antenna high on the mast, to prevent inaccurate speed readings caused by excessive heeling.
