NOTICE
If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid any cracking in the gel-coat layer when the screws are tightened.
NOTICE
Stainless-steel screws may bind when screwed into fiberglass and overtightened.
Garmin® recommends applying an anti-seize lubricant to the screws before installing them.
Before you permanently mount the antenna, you must test the mounting location for correct operation (Antenna Mounting Considerations).
-
Using the surface-mount bracket as your mounting template, mark the three pilot-hole locations and trace the cable-hole in the center of the bracket.
-
Set the surface-mount bracket aside.
Do not drill through the bracket.
-
Drill the three 3.2 mm (1/8 in.) pilot holes.
-
Use a 25 mm (1 in.) hole saw to cut the cable hole in the center.
-
Place the seal pad on the bottom of the surface-mount bracket, aligning the screw holes.
-
Use the included M4 screws to secure the surface-mount bracket to the mounting surface.
-
Route the cable through the 25 mm (1 in.) hole and connect it to the antenna.
-
Verify the large gasket is in place on the bottom of the antenna, place the antenna on the surface-mount bracket, and twist it clockwise to lock it in place.
-
Secure the antenna to the mounting bracket with the included M3 set screw .
-
Route the cable away from sources of electronic interference.
