Mounting the Antenna with the Cable Routed Through the Pole

Before you permanently mount the antenna, you must test the mounting location for correct operation (

Testing 

the Mounting Location, page 3

).

Position a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not included) in the selected location, 

and mark the approximate center of the pole.

Use a 19 mm (

/

 in.) drill bit to drill a hole for the cable to pass through.

Fasten the pole to the boat.
Thread the pole-mount adapter onto the pole.

Do not overtighten the adapter.

Route the cable through the pole and connect it to the antenna.
Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place.
Use the included M3 set screw and a 1.5 mm hex wrench to secure the antenna to the adapter  .

With the antenna installed on the pole mount, fill the vertical cable slot   with a marine sealant (optional).
Route the cable away from sources of electronic interference.
