Antenna Mounting Considerations

You can mount the antenna on a flat surface, install it under fiberglass, or attach it to a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not included). You can route the cable outside of the pole or through the pole. For best performance, consider these guidelines when selecting the antenna mounting location.

- To ensure the best reception, the antenna should be mounted in a location that has a clear, unobstructed view of the sky in all directions ①.

• The antenna should not be mounted where it is shaded by the superstructure of the boat ②, a radome antenna, or the mast.
• The antenna should not be mounted near the engine or other sources of Electromagnetic Interference (EMI) ③.
• If a radar is present, the antenna should be mounted above the path of the radar ④. If necessary, the antenna may be mounted below the path of the radar ⑤.

• The antenna should not be mounted directly in the path of the radar ⑥.
• The antenna should be mounted at least 3 ft. (1 m) away from (preferably above) the path of a radar beam or a VHF radio antenna ⑦.

Testing the Mounting Location

1 Temporarily secure the antenna in the preferred mounting location and test it for correct operation.
2 If you experience interference with other electronics, move the antenna to a different location, and test it again.
3 Repeat steps 1–2 until you observe full or acceptable signal strength.
4 Permanently mount the antenna.

Surface Mounting the Antenna

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.

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).

1 Using the surface-mount bracket ① as your mounting template, mark the three pilot-hole locations and trace the cable-hole in the center of the bracket.

2 Set the surface-mount bracket aside. Do not drill through the bracket.
3 Drill the three ¹/₈ in. (3.2 mm) pilot holes.
4 Use a 1 in. (25 mm) hole saw to cut the cable hole in the center.
5 Place the seal pad ② on the bottom of the surface-mount 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 ③ through the 1 in. (25 mm) hole and connect it to the antenna.
8 Verify that the large gasket ④ 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.
9 Secure the antenna to the mounting bracket with the included M3 set screw ⑤.
10 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 (Antenna Mounting Considerations).

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 34 in. (19 mm) 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.
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 ①.

8 With the antenna installed on the pole mount, fill the vertical cable slot ② with a marine sealant (optional).
9 Route 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 (Antenna Mounting Considerations).

1 Route the cable through the pole-mount adapter ①, and place the cable in the vertical slot ② along the base of the pole-mount adapter.

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 ③.
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 Under the Deck

NOTICE

Before attaching the under-deck mounting bracket to the surface, verify the supplied screws will not penetrate the surface. If the supplied 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 (Antenna Mounting Considerations).

Because the antenna cannot acquire signals through metal, it must be mounted under a fiberglass surface only.

Even when mounted under fiberglass, mounting this antenna below deck decreases SiriusXM signal reception. If you are operating off-shore, an above-deck mounting location free of obstructions is recommended.

1 Place the adhesive pads ① on the under-deck mounting bracket ②.

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 ③.
6 Route the cable away from sources of electronic interference.

NMEA 2000 Connection Considerations

The antenna connects to a NMEA 2000 network on your boat. The NMEA 2000 network provides power to the antenna and shares data with other NMEA 2000-compatible devices on the network. The included NMEA 2000 cable and connector allow you to connect the device to your existing NMEA 2000 network. If you do not have an existing NMEA 2000 network on your boat, you must create one.

If you are unfamiliar with NMEA 2000, you should read the "NMEA 2000 Network Fundamentals" chapter of the Technical Reference for NMEA 2000 Products. To download this document, select Manuals on the product page for your device at www.garmin.com.
