GPSMAP 3000 Series Installation Instructions
The GPS 17x antenna provides more-stable readings when located nearer to water level.
Mount the GPS 17x antenna at least 3 ft. (1 m) away from (preferably above) the path
of any radar beam or a VHF radio antenna.
Temporarily secure the antenna in the preferred mounting location and test it for correct
operation. If you experience interference with other electronics, try a different location.
When you verify correct operation, permanently mount the antenna.

NotE: If you are mounting the GPS 17x on fiberglass, it is recommended to use a countersink bit to drill a clearance counterbore through the top
gelcoat layer (but no deeper). This will help to avoid cracking in the gelcoat layer when the screws are tightened.

Pole Mounting the GPS 17x Antenna
With the pole-mount adapter attached to the GPS 17x, you can install the GPS 17x on a
standard 1 in. OD pipe-threaded-pole marine mount (14 threads per inch—not included). You can run the GPS 17x cable through the pole or
outside the pole.
To mount the GPS 17x with the cable run outside the pole:
1. RoutetheGPS17xdropcablethroughthepole-mountadapter,andplacethecableintheverticalslotalongthebaseofthepole-mount
