Frequently Asked Questions - GA 30 GPS Antenna GARMIN

How to install the GA 30 antenna?

Fix the antenna on a flat and unobstructed surface using the provided screws or a magnetic mount (not included). Connect the BNC connector to the ANT input of your Garmin receiver. Make sure the cable is not pinched.

Which Garmin receivers are compatible with the GA 30?

The GA 30 is compatible with most Garmin receivers equipped with a BNC connector, such as the GPSMAP series, echoMAP, and some aviation models. Check your device's manual.

Is the GA 30 antenna waterproof?

Yes, it is IPX7 certified, meaning it can withstand immersion up to 1 meter for 30 minutes.

Can I use the GA 30 with a non-Garmin receiver?

Technically yes, if the receiver has a BNC antenna input and operates on GPS L1. However, performance is not guaranteed.

What is the cable length of the antenna?

The cable is 5 meters long, allowing flexible installation.

How to maintain the GA 30 antenna?

Clean it regularly with a soft, damp cloth. Avoid solvents. Check that the cable and connector are not damaged.

What to do if the antenna does not pick up any signal?

Check the BNC connection, make sure the antenna is placed in an open area (not under a bridge or in a garage). Restart the receiver.

Does the antenna require an external power supply?

No, it is powered directly by the GPS receiver via the coaxial cable. No battery or power adapter needed.

Can I extend the antenna cable?

Yes, but use a good quality BNC coaxial extension cable. An extension that is too long (>10 m) may weaken the signal.

Where can I find the complete user manual?

The manual is available for free download on sites like notice-facile.com or on the official Garmin website.

Packing List and Tools Needed

Before installing your unit, confirm that your package includes the following items. If any parts are missing, contact your Garmin dealer immediately.

Standard Package

• GA 30 antenna
• Antenna cable
  • Surface-mount bracket
• Pole-mount bracket
  • Under-deck mount bracket
  • Mounting hardware (screws and adhesive pads)
  • Installation instructions

Tools Needed

• Drill and drill bits
• Hole saw, 1 in. (25 mm) (surface-mount cable hole)
• Screwdriver (surface-mount screws)
  • Center punch and hammer (to mark surface-mount pilot holes)
• Countersink bit (when mounting on fiberglass)
  • Marine sealant (for certain mounting options)

Mounting the GA 30 Antenna

You can surface mount the GA 30 antenna, attach the antenna to a standard 1 in. OD pipe-threaded-pole marine mount (14 threads-per-inch—not included), or install the antenna under fiberglass.

Select a suitable location for the GA 30 antenna on your boat. To ensure the best reception, mount the GA 30 antenna in a location that is clearly exposed to the sky in all directions.

• Avoid mounting the GA 30 antenna in the shade of the superstructure of the boat, a radome antenna, or a mast.
• Mount the GA 30 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 from other electronics, try a different location. When you verify correct operation, permanently mount the antenna.

GA 30 Antenna Placement Considerations

Surface Mounting the GA 30 Antenna

1 Use the surface-mount bracket as your mounting template.

• Use a 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.

• Drill 18 in. (3 mm) pilot holes at the three marked locations.

NOTE: If you are mounting the GA 30 on fiberglass, it is recommended that you use a countersink bit to drill a clearance counterbore through the top gelcoat layer (but no deeper). This will help to prevent cracking in the gelcoat layer when the screws are tightened.

1. Use a 1 in. (25 mm) hole saw to cut the cable hole in the center.
2. Place the seal pad on the bottom of the surface-mount bracket. Ensure that the screw holes align.
3. Use the included M4 screws to attach the surface-mount bracket to the mounting surface.
4. Route the cable through the 1 in. cable hole and connect it to the GA 30.
5. Ensure that the large rubber gasket is in place on the bottom of the GA 30 antenna, place the antenna on the surface-mount bracket ①, and twist the antenna clockwise to lock it in place ②.

1. Secure the antenna to the mounting bracket with the included M3 set screw ③.
2. Route the cable away from sources of electronic interference, and connect it to your GPS device using the BNC connector.

Pole Mounting the GA 30 Antenna

With the pole-mount adapter attached to the GA 30 antenna, you can install the antenna on a standard 1 in. OD pipe-threaded-pole marine mount (14 threads per inch—not included). You can run the cable through the pole or outside the pole.

To mount the GA 30 with the cable run outside the pole:

1. Route the 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 cable to the GA 30 antenna.

4. Place the GA 30 antenna on the pole-mount adapter ① and twist the antenna clockwise to lock it in place ②.

5. Secure the antenna to the adapter with the included M3 set screw ③.

6. (Optional) With the GA 30 installed on the pole mount, fill the remaining gap in the vertical cable slot with a marine sealant.

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

8. Route the cable away from sources of electronic interference, and connect it to your GPS device using the BNC connector.

To mount the GA 30 with the cable run through the pole:

1. Position a standard 1 in. OD pipe-threaded-pole marine mount (14 threads per inch—not included) in the preferred location, and mark the approximate center of the pole.
2. Drill a 34 in. (19 mm) hole for the cable to pass through.
3. Fasten the pole marine mount 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 GA 30 antenna.
6. Place the GA 30 antenna on the pole-mount adapter ① and twist the antenna clockwise to lock it in place ②.
7. Secure the antenna to the adapter with the included M3 set screw ③.
8. (Optional) With the GA 30 installed on the pole mount, fill the vertical cable slot with a marine sealant.
9. Route the cable away from sources of electronic interference, and connect it to your GPS device using the BNC connector.

Under-deck Mounting the GA 30 Antenna

The GA 30 antenna can be mounted under a fiberglass surface with the adhesive pads attached to the under-deck mounting bracket. The GA 30 will not acquire satellite signals through metal—you can only use the under-deck mount under a fiberglass surface.

1. Determine the location on the fiberglass surface where you want to mount the GA 30.
2. Place the adhesive pads on the under-deck mounting bracket.
3. Place the GA 30 in the underdeck mounting bracket.
4. Adhere the under-deck mounting bracket to the mounting surface.
5. Secure the under-deck mount to the mounting surface with screws. Use extreme care to ensure that the screws do not penetrate the upper surface of the deck.
6. Connect the cable to the GA 30.
7. Route the cable away from sources of electronic interference, and connect it to your GPS device using the BNC connector.
