Garmin GA 38 GPS/GLONASS Antenna Installation Instructions - Page 3

5 Place the seal pad on the bottom of the surface-mount Á bracket, aligning the screw holes. 6 Use the included M4 screws to secure the surface-mount bracket to the mounting surface. 7 Route the cable through the 25 mm (1 in.) hole and  connect it to the antenna. 8 Verify the large gasket is in place on the bottom of the à antenna, place the antenna on the surface-mount bracket, and twist it clockwise to lock it in place. 9 Secure the antenna to the mounting bracket with the included M3 set screw . Ä 10Route the cable away from sources of electronic interference. Mounting the Antenna with the Cable Routed Outside the Pole Before you permanently mount the antenna, you must test the mounting location for correct operation (Testing the Mounting Location, page 2). 1 Route the cable through the pole-mount adapter , and À place the cable in the vertical slot along the base of the Á pole-mount adapter. 5 Route the cable through the pole and connect it to the antenna. 6 Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place. 7 Secure the antenna to the adapter with the included M3 set screw . À 2 Screw the pole-mount adapter onto a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not included). Do not overtighten the adapter on the pole. 3 Connect the cable to the antenna. 4 Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place. 5 Secure the antenna to the adapter with the included M3 set screw .  6 With the antenna installed on the pole mount, fill the remaining gap in the vertical cable slot with a marine sealant (optional). 7 Attach the pole to the boat if it is not already attached. 8 Route the cable away from sources of electronic interference. 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 2). 1 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. 2 Drill a hole using a 19 mm (3/4 in.) drill bit for the cable to pass through. 3 Fasten the pole to the boat. 4 Thread the pole-mount adapter onto the pole. Do not overtighten the adapter. 8 With the antenna installed on the pole mount, fill the vertical cable slot with a marine sealant (optional). Á 9 Route the cable away from sources of electronic interference. Mounting the Antenna Under the Deck NOTICE Before attaching the under-deck mounting bracket to the surface, verify the included screws will not penetrate the surface. If the included screws are too long, you must purchase surface-appropriate screws to complete the installation. Before you permanently mount the antenna, you must test the mounting location for correct operation (Testing the Mounting Location, page 2). Because the antenna cannot acquire signals through metal, it must be mounted under a fiberglass surface only. 1 Place the adhesive pads on the under-deck mounting À bracket . Á 2 Place the antenna in the under-deck mounting bracket. 3 Adhere the under-deck mounting bracket to the mounting surface. 4 Secure the under-deck mounting bracket to the mounting surface with screws. 5 Connect the cable to the antenna .  6 Route the cable away from sources of electronic interference.
