• The GPS 17x antenna provides more-stable readings when located nearer to water level. • 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. EMI Better Best Good SS BARNETT EMI (Electromagnetic Interference) from engine components 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. Drill the three 1/8 in. (3 mm) pilot holes. Above - best Below - OK Radar 3 ft. (1 m) VHF Radio Antenna GPS 17x Placement Considerations 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. ➊ 6. Route the GPS 17x cable through the 1 in. cable hole and connect it to the GPS 17x. 7. Make sure the large gasket is in place on the bottom of the GPS 17x antenna, place the antenna on the surface-mount bracket ➊, and twist it clockwise to lock it in place ➋. 8. Secure the antenna to the mounting bracket with the included M3 set screw ➌. Surface-mount bracket Seal pad 9. Route the GPS 17x cable away from sources of electronic interference, and Mounting connect it to power and to your GPSMAP 3000 series chartplotter (Page 6). surface ➋ GPS 17x antenna ➌ Rubber gasket Pole Mounting the GPS 17x Antenna With the pole-mount adapter attached to the GPS 17x, you can install the GPS 17x on a standard 1 in. OD pipe-threaded-pole marine mount (14 threads per inch-not included). You can run the GPS 17x cable through the pole or outside the pole. To mount the GPS 17x with the cable run outside the pole: 1. Route the GPS 17x drop cable through the pole-mount adapter, and place the cable in the vertical slot along the base of the pole-mount adapter. 2. Thread the pole-mount adapter onto a standard 1 in. OD pipe-threaded-pole marine mount (14 threads per inch-not included). Do not overtighten the adapter. 3. Connect the GPS 17x cable to the GPS 17x antenna. 4. Place the GPS 17x antenna on the pole-mount adapter ➊ and twist it clockwise to lock it in place ➋. 5. Secure the antenna to the adapter with the included M3 set screw ➌. ➊ ➋ ➌ GPS 17x antenna 6. (Optional) With the GPS 17x installed on the pole mount, fill the remaining gap in the vertical cable slot with a marine sealant. 7. Attach the marine mount to the boat if it is not already attached. 8. Route the GPS 17x cable away from sources of electronic interference, and connect it to power and to your GPSMAP 3000 series chartplotter (Page 6). Pole-mount adapter To mount the GPS 17x with the cable run through the pole: Vertical cable 1. Position a standard 1 in. OD pipe-threaded-pole marine mount (14 threads per inch-not included) slot in the preferred location, and mark the approximate center of the pole. 2. Drill a hole using a 3/4 in. (19 mm) drill bit for the cable to pass through. 3. Fasten the marine mount to the boat. GPSMAP 3000 Series Installation Instructions
