Mounting the GA 30 Antenna You can surface mount the GA 30 antenna, attach the antenna to a standard 1 in. OD pipe- threaded-pole marine mount (14 threads-per-inch-not included), or install the antenna under fiberglass. Select a suitable location for the GA 30 antenna on your boat. To ensure the best reception, mount the GA 30 antenna in a location that is clearly exposed to the sky in all directions. • Avoid mounting the GA 30 antenna in the shade of the superstructure of the boat, a radome antenna, or a mast. • Mount the GA 30 antenna at least 3 ft. (1 m) away from (preferably above) the path of any radar beam or a VHF radio antenna. Temporarily secure the antenna in the preferred mounting location and test it for correct operation. If you experience interference from other electronics, try a different location. When you verify correct operation, permanently mount the antenna.

Do not drill through the surface-mount bracket. 2. Drill 1/8 in. (3 mm) pilot holes at the three marked locations. Note: If you are mounting the GA 30 on fiberglass, it is recommended that you use a countersink bit to drill a clearance counterbore through the top gelcoat layer (but no deeper). This will help to prevent cracking in the gelcoat layer when the screws are tightened. 3. Use a 1 in. (25 mm) hole saw to cut the cable hole in the center. 4. Place the seal pad on the bottom of the surface-mount bracket. Ensure that the screw holes align. 5. Use the included M4 screws to ➋ attach the surface-mount bracket to the mounting surface. 6. Route the cable through the 1 in. ➊ cable hole and connect it to the GA 30 antenna ➌ GA 30. 7. Ensure that the large rubber gasket is in place on the bottom of the GA 30 antenna, place the antenna on the surface-mount bracket ➊, and twist the antenna clockwise to lock it in place ➋.
