GPSMAP 4000/5000 Series Installation Instructions
4. At the marked location, use a
3
/
4
in. (19 mm) bit to drill a hole for the cable to pass through.
5. Fasten the marine pole mount to the boat (hardware not included).
6. Thread the pole-mount bracket
➊
onto the marine pole mount.
Do not overtighten the bracket.
7. Route a NMEA 2000 drop cable through the pole-mount bracket and the pole, and connect the cable to the antenna.
8. Place the antenna on the pole-mount bracket, and twist it clockwise
➌
to lock it in place.
9. Secure the antenna to the bracket with the included M3 set screw
➍
.
10. Route the NMEA 2000 drop cable away from sources of electronic interference.
11. Connect the antenna to your NMEA 2000 network.
12. After the antenna is installed on the pole mount, fill the vertical cable slot with a marine sealant (optional).
Mounting the Antenna under a Surface
notice
When choosing a location to install the under-deck-mounting bracket, make sure the included screws are not too long for the surface thickness. If the screws
are not appropriate for the surface, you must supply the correct length of M4 screws to avoid damage to the top of the mounting surface.
The antenna can be mounted under a fiberglass surface. Because the antenna has difficulty acquiring cellular signals through metal, it is
recommended that you use the under-deck mount under a fiberglass surface.
1. Identify the mounting location on the fiberglass surface
➊
, and verify correct operation
at the mounting location.
2. Using the under-deck-mounting bracket
➋
as a template, mark three pilot-hole locations
➌
on the surface.
3. Use a
1
/
8
in. (3.2 mm) bit to drill the three marked pilot holes.
4. Place the antenna in the bracket, and twist it clockwise to lock it in place.
5. Secure the antenna to the bracket with the included M3 set screw
➍
.
6. Remove the backing from the adhesive pads
➎
on the under-deck mounting bracket.
7. Make sure that the bracket aligns with the pilot holes, and adhere the under-deck
mounting bracket to the surface.
8. Using screws of the appropriate length, fasten the bracket to the surface.
9. Connect a NMEA 2000 drop cable to the antenna
