INSTALLATION

INSTRUCTIONS

Important Safety Information

CAUTION

To avoid possible personal injury, always wear safety goggles,
ear protection, and a dust mask when drilling, cutting, or
sanding.

NOTICE

When drilling or cutting, always check what is on the opposite
side of the surface to avoid damaging the vessel.

For the best performance and to avoid damage to your boat,
read all installation instructions before proceeding. Install the
device per these instructions. Use the appropriate fasteners,
tools, and mounts listed, which are available at most marine
dealers.

For more information, go to support.garmin.com.

Tools Needed

• Drill

• 3.2 mm (1/8 in.) drill bit

• 19 mm (3/4 in.) drill bit for a pole-mount cable-hole

• 25 mm (1 in.) hole saw for a surface-mount cable-hole

• Countersink bit for mounting on fiberglass

• Screws for under-deck mounting

• Screwdriver, appropriate for the screw type

• Marine sealant (optional)

• Additional NMEA 2000 network components as needed

• The antenna should not be mounted where it is shaded by
the superstructure of the boat , a radome antenna, or the
mast.

• The antenna should not be mounted near the engine or other
sources of Electromagnetic Interference (EMI) .

• The antenna should not be mounted near known ferrous
metal objects such as a toolbox or compass.

• If a radar is present, the antenna should be mounted above
the path of the radar . If necessary, the antenna may be
mounted below the path of the radar .

• The antenna should not be mounted directly in the path of the
radar .

• The antenna should not be mounted within 1 m (3 ft.) of a
VHF radio antenna or the path of a radar .

Mounting the Antenna

Antenna Mounting Considerations

CAUTION

Do not install or store the antenna near strong magnets,
including speakers. A strong magnetic field can damage the
antenna.

You can mount the antenna on a flat surface 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 .

Testing the Mounting Location

Temporarily secure the antenna in the preferred mounting

1

location and test it for correct operation.
If you experience interference with other electronics, move

2

the antenna to a different location, and test it again.
Repeat steps 1–2 until you observe full or acceptable signal

3

strength.
Permanently mount the antenna.

4

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 cracking in the gel-coat layer when the screws are
tightened.

Before you permanently mount the antenna, you must test the
mounting location for correct operation (Testing the Mounting

Location, page 1).

Using the surface-mount bracket as your mounting

1

template, mark the three pilot-hole locations and trace the
cable-hole in the center of the bracket.

GUID-512A740F-7146-4626-9C08-48DB06A8A4EE v1January 2021

Set the surface-mount bracket aside.

2

Do not drill through the bracket.
Drill the three 3.2 mm (1/8 in.) pilot holes.

3

Drill the 25 mm (1 in.) cable hole in the center.

4

Use the included M4 screws to secure the surface-mount

5

bracket to the mounting surface.
Route the cable through the center hole, and connect it to

6

the antenna.
Verify the large gasket is in place on the bottom of the

7

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

8

M3 screw .
Route the cable away from sources of electronic interference.

9

Mounting the Antenna on a Pole

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 1).

Route the cable through the pole-mount adapter , and

1

place the cable in the vertical slot along the base of the
pole-mount adapter.

With the antenna installed on the pole mount, fill the

6

remaining gap in the vertical cable slot with a marine sealant
(optional).

Attach the pole to the boat if it is not already attached.

7

Route the cable away from sources of electronic interference.

8

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 1).

Position a standard 1 in. OD, 14 threads per inch, pipe-

1

threaded pole (not included) in the selected location, and
mark the approximate center of the pole.

Drill a hole using a 19 mm (3/4 in.) drill bit for the cable to

2

pass through.
Fasten the pole to the boat.

3

Thread the pole-mount adapter onto the pole.

4

Do not overtighten the adapter.
Route the cable through the pole and connect it to the

5

antenna.
Place the antenna on the pole-mount adapter and twist it

6

clockwise to lock it in place.
Secure the antenna to the adapter with the included M3 set

7

screw .

Screw the pole-mount adapter onto a standard 1 in. OD, 14

2

threads per inch, pipe-threaded pole (not included).
Do not overtighten the adapter on the pole.
Connect the cable to the antenna.

3

Place the antenna on the pole-mount adapter and twist it

4

clockwise to lock it in place.
Secure the antenna to the adapter with the included M3 set

5

screw .

2

With the antenna installed on the pole mount, fill the vertical

8

cable slot with a marine sealant (optional).
Route the cable away from sources of electronic interference.

9

Mounting the Antenna Under a Surface

NOTICE

Verify that the supplied screws will not penetrate the surface
before you install the under-deck mounting bracket. If the
supplied screws are too long, use surface-appropriate screws
instead.

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

1

where you want to mount the antenna (Testing the Mounting

Location, page 1).
