Mounting type and Location Considerations

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

The antenna must be mounted 5.9 in. (150 mm) from a compass to avoid interference.
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 ➊.
The antenna should not be mounted where it is shaded by the superstructure of the boat ➋, a radome antenna, or the mast.
The antenna should not be mounted near the engine or other sources of Electromagnetic Interference (EMI) ➌.
If a radar is present, it is best to install the antenna above the path of the radar ➍, though it is acceptable to install it below the path of the radar ➎ if necessary. The antenna should not be installed directly in the path of the radar ➏.
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 ➐.
On a sailboat, to prevent inaccurate speed readings caused by excessive heeling, the antenna should not be mounted high on the mast.
The antenna provides more-stable readings when located nearer to water level.

testing the Mounting Location

Temporarily secure the antenna in the preferred mounting location and test it for correct operation.
If you experience interference with other electronics, move the antenna to a different location, and test it again.
Repeat steps 1–2 until you can verify that the antenna operates correctly.
Permanently mount the antenna.

Surface-Mounting the Antenna

Before you permanently mount the antenna, test the mounting location for correct operation (page 1). Use the surface-mount bracket ➊ as your mounting template.

Use a pencil to mark the three screw locations and 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.
Drill the three 1/8 in. (3.2 mm) pilot holes.
NotE: If you are mounting the GPS 19x on fiberglass, it is recommended to use a countersink bit to drill a clearance counterbore through the top gel coat layer (but no deeper). This will help to avoid cracking in the gel coat layer when the screws are tightened.
Use a 1 in. (25 mm) hole saw to cut the cable hole in the center.
Place the seal pad ➋ on the bottom of the surface-mount bracket, aligning the screw holes.
Use the included M4 screws to attach the surface-mount bracket to the mounting surface.
Route the cable ➌ through the 1 in. (25 mm) hole and connect it to the antenna.
Verify that the large gasket ➍ 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.
Secure the antenna to the mounting bracket with the included M3 set screw ➎.
Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network (page 3).

Mounting the Antenna on a Pole

With the included pole-mount adapter attached to the antenna, you can install it on 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.
Before you permanently mount the antenna, test the mounting location for correct operation (page 1).

Mounting the Antenna with the Cable Routed outside of the Pole

Route the cable through the pole-mount adapter, and place the cable in the vertical slot ➋ along the base of the pole-mount adapter.
Screw the pole-mount adapter onto a standard 1 in. OD, 14 threads per in., pipe-threaded pole (not included). Do not overtighten the adapter on the pole.
Connect the cable to the antenna.
Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place.
Secure the antenna to the adapter with the included M3 set screw ➌.
With the antenna installed on the pole mount, fill the remaining gap in the vertical cable slot with a marine sealant (optional).
Attach the pole to the boat if it is not already attached.
Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network (page 3).

Mounting the Antenna with the Cable Routed through the Pole

Position a standard 1 in. OD, 14 threads per in., pipe-threaded pole (not included) in the selected location, and mark the approximate center of the pole.
Drill a hole using a 3/4 in. (19 mm) drill bit for the cable to pass through.
Fasten the pole to the boat.
Thread the pole-mount adapter onto the pole. Do not overtighten the adapter.
Route the cable through the pole and connect it to the antenna.
Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place.
Secure the antenna to the adapter with the included M3 set screw ➊.
With the antenna installed on the pole mount, fill the vertical cable slot ➋ with a marine sealant (optional).
Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network (page 3).

Mounting the Antenna under a Surface

Notice
Before attaching the under-deck mounting bracket to the surface, verify that 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. Because the antenna cannot acquire signals through metal, it must be mounted under a fiberglass surface only.

Determine and test the location under a fiberglass surface where you want to mount the antenna (page 1).
Place the adhesive pads ➊ on the under-deck mounting bracket ➋.
Place the antenna in the under-deck mounting bracket.
Adhere the under-deck mounting bracket to the mounting surface.
Secure the under-deck mounting bracket to the mounting surface with screws.
Connect the cable to the antenna ➌.
Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network (page 3).

Connecting the Antenna to Your NMEA 2000 Network

If you do not have an existing NMEA 2000 network, you must install an NMEA 2000 network on your boat. For more information on NMEA 2000, go to www. garmin.com. The antenna is packaged with a NMEA 2000 T-connector and a NMEA 2000 drop cable. You will use these two components to connect the antenna to your existing NMEA 2000 network.

Determine an appropriate location to connect the antenna ➊ to your existing NMEA 2000 backbone ➋.
Disconnect one side of a NMEA 2000 T-connector ➌ from the backbone nearest to the location where you want to connect the antenna. If you need to extend the NMEA 2000 backbone, connect an appropriate NMEA 2000 backbone extension cable (not included) to the side of the T-connector you disconnected.
Connect a T-connector (included) in the NMEA 2000 backbone.
Route a drop cable (included) ➍ from the GPS 19x antenna to the top of the T-connector you added to your NMEA 2000 network. If the included drop cable is not long enough, you can add a drop cable extension up to 13 ft. (4 m). If more cable is needed, add an extension to your NMEA 2000 backbone, based on the NMEA 2000 guidelines.
