GPS 17x NMEA 0183 HVS Installation Instructions

Step 1: 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.
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.

Surface-mounting the GPS 17x Antenna

1. Use the surface-mount bracket as your mounting template

Use the center punch to mark the three screw locations on the surface.
Use a pencil to trace the cable hole in the center of the bracket.
Set the surface-mount bracket aside. Do not drill through the surface-mount bracket.

2. Select the appropriate drill bit for your mounting surface using the drill bit table (

page 1

), and

drill the three pilot holes.

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.

3. Use a 1 in. (25 mm) hole saw to cut the cable hole in the center.
4. Place the seal pad on the bottom of the surface-mount bracket. Make sure that the screw holes align.
5. Use the included M4 screws to

attach the surface-mount bracket to

the mounting surface.

6. Route the power/data cable through

the 1 in. cable hole and connect it

to the GPS 17x.

7. Make sure the large gasket is in

place on the bottom of the GPS 17x

antenna, place the antenna on the

surface-mount bracket

➊

, and twist

it clockwise to lock it in place

➋

8. Secure the antenna to the mounting

bracket with the included M3 set

screw

➌

9. Route the power/data cable away from sources of electronic interference, and connect it to

power and a NMEA 0183-compliant device. (
