Under-Deck-Mounting The Gps 17X Antenna - Garmin GPSMAP 4008 Installation Instructions Manual

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 NMEA 2000 cable through the pole or outside the pole.
To mount the GPS 17x with the cable run outside the pole:
1. Route the NMEA 2000 drop cable through the pole-mount adapter, and place the cable in the vertical slot along the base of the pole-mount
adapter.
2. Thread the pole-mount adapter onto a standard 1 in. OD pipe-threaded-pole marine mount (14 threads per inch—not included). Do not
overtighten the adapter.
3. Connect the NMEA 2000 drop cable to the GPS 17x antenna.
4. Place the GPS 17x antenna on the pole-mount adapter
5. Secure the antenna to the adapter with the included M3 set screw
6. (Optional) With the GPS 17x installed on the pole mount, fill the remaining gap in the vertical cable
slot with a marine sealant.
7. Attach the marine mount to the boat if it is not already attached.
8. Route the cable away from sources of electronic interference, and connect it to your NMEA 2000
network.
To mount the GPS 17x with the cable run through the pole:
1. Position a standard 1 in. OD pipe-threaded-pole marine mount (14 threads per inch—not included)
in the preferred location, and mark the approximate center of the pole.
2. Drill a hole using a / in. (19 mm) drill bit for the cable to pass through.

4. Thread the pole-mount adapter onto the pole. Do not overtighten the adapter.
5. Route the NMEA 2000 drop cable through the pole and connect it to the GPS 17x antenna.
6. Place the GPS 17x antenna on the pole-mount adapter

9. Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network.

Under-deck-mounting the GPS 17x Antenna

The GPS 17x can be mounted under a fiberglass surface with the included adhesive pads. The GPS 17x will not acquire satellite signals through
metal—you can only use the under-deck mount under a fiberglass surface.
1. Determine the location on the fiberglass surface where you want to mount the
GPS 17x.
2. Place the adhesive pads on the under-deck mounting bracket.
There are holes in the under-deck mounting bracket that can be used to secure
the under-deck mount to the mounting surface with screws. Garmin does not
recommend attaching the under-deck mounting bracket to the surface with
screws, because of the likelihood that screws will extend beyond the top of the
mounting surface. If you choose to use screws, do so with extreme care.
3. Place the GPS 17x in the under-deck mounting bracket.
4. Adhere the under-deck mounting bracket to the mounting surface.
5. Connect the NMEA 2000 drop cable to the GPS 17x.
6. Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network.
