EN Step 1: Mount the GPS 17x Antenna You can surface mount the GPS 17x antenna, attach it to a standard 1 in. OD pipe-threaded-pole marine mount (14 threads-per-inch-not included), or even install the antenna under fiberglass. Select a suitable location for the GPS 17x antenna on your boat. To ensure the best reception, mount the GPS 17x antenna in a location that has a clear, unobstructed view of the sky in all directions. • Avoid mounting the GPS 17x antenna where it is shaded by the superstructure of the boat, a radome antenna, or mast. EMI Better Best Good SS BARNETT EMI (Electromagnetic Interference) from engine components Above - best • On a sailboat, avoid mounting the GPS 17x antenna high on the mast, to prevent inaccurate speed readings caused by excessive heeling. • The GPS 17x antenna provides more-stable readings when located nearer to water level. Below - OK Radar 3 ft. (1 m) VHF Radio Antenna GPS 17x Placement Considerations • Mount the GPS 17x 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 with other electronics, try a different location. When you verify correct operation, permanently mount the antenna. Surface-mounting the GPS 17x Antenna 1. Use the surface-mount bracket as your mounting template • Use the center punch to mark the three screw locations on the surface. • Use a pencil to trace the cable hole in the center of the bracket. • Set the surface-mount bracket aside. Do not drill through the surface-mount bracket. 2. Select the appropriate drill bit for your mounting surface using the drill bit table (page 1), and drill the three pilot holes. Note: If you are mounting the GPS 17x on fiberglass, it is recommended to use a countersink bit to drill a clearance counterbore through the top gelcoat layer (but no deeper). This will help to avoid 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. Make sure that the screw holes align. 5. Use the included M4 screws to attach the surface-mount bracket to the mounting surface. 6. Route the power/data cable through ➊ the 1 in. cable hole and connect it to the GPS 17x. ➋ GPS 17x antenna ➌ 7.
