Mounting The Antenna With The Cable Routed Outside The Pole; Connection Considerations - Garmin GXM 54 Installation Instructions Manual

Mounting the Antenna with the Cable Routed Outside the Pole

Before you permanently mount the antenna, you must test the mounting location for correct operation
the Mounting Location, page 3).
1 Route the cable through the pole-mount adapter
of the pole-mount adapter.
2 Screw the pole-mount adapter onto a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not
included).
Do not overtighten the adapter on the pole.
3 Connect the cable to the antenna.
4 Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place.
5 Use the included M3 set screw and a 1.5 mm hex wrench to secure the antenna to the adapter
6 With the antenna installed on the pole mount, fill the remaining gap in the vertical cable slot with a marine
sealant (optional).
7 Attach the pole to the boat if it is not already attached.
8 Route the cable away from sources of electronic interference.

Connection Considerations

If you are connecting the audio cable from the wiring harness, you must connect it to the line-in or auxiliary port
on a stereo. Attempting to connect the audio cable directly to a speaker will result in poor performance, and it
may cause the antenna to shut down, which might damage the antenna or the speaker.
You must connect this antenna to power and to the Garmin Marine Network to provide weather information to
connected, compatible Garmin devices.
