Antena GPS/GLONASS GA™ 38 – VHF, AIS i nadawcy pozycyjne

The Garmin GA™ 38 antenna is an external GPS and GLONASS positioning antenna designed to enhance navigation accuracy on compatible marine systems. It integrates with a range of Garmin devices, including chartplotters, VHF radios, and AIS systems, providing reliable and fast location data. It allows for optimized installation for maximum signal reception, unlike built-in antennas.

The Garmin GA™ 38 antenna uses GPS and GLONASS positioning technologies for improved signal acquisition and accuracy.

The Garmin GA™ 38 antenna has a diameter of 91.6 mm (3 19/32 in) and a height of 49.5 mm (1 15/16 in). Its weight is 201 grams (7.1 oz).

For the white model of the GA™ 38 antenna, the operating temperature range is -30°C to 80°C (-22°F to 176°F).

The Garmin GA™ 38 antenna has an IEC 60529 IPX7 waterproof rating, meaning it is protected against temporary immersion in water.

The Garmin GA™ 38 antenna housing is made of high-impact plastic alloy and is fully watertight.

Yes, it is important not to install or store the GA™ 38 antenna near strong magnets, including speakers, as a strong magnetic field can damage the antenna.

The Garmin GA™ 38 antenna is compatible with a range of Garmin marine devices, including chartplotters, VHF radios, and AIS systems.

The GA™ 38 antenna uses a standard BNC connector to connect to the dedicated ports labeled 'ANTENNA' or 'EXT GPS' on compatible Garmin chartplotters.

The Garmin GA™ 38 antenna offers several mounting options:

On a flat surface using the included surface-mount bracket.
On a standard 1-inch outer diameter threaded mast with 14 threads per inch (mast not included).
Under the deck, only under a fiberglass surface (the under-deck mounting kit is provided with white antenna models).

For optimal reception, the antenna must be mounted in a location with an unobstructed view of the sky in all directions. It must not be shaded by the boat's superstructure, a radome antenna, or the mast.

Yes, it is recommended to avoid installing the GA™ 38 antenna:

Near the engine or other electromagnetic interference (EMI) sources.
Near ferrous metal objects, such as a toolbox or a compass.
Directly in the path of a radar.
Within 1 meter (3 feet) of a VHF radio antenna or in the path of a radar.

To test the mounting location:

Temporarily secure the antenna at the chosen location and verify its proper operation. If you experience interference with other electronic devices, move the antenna to another spot and test again. Repeat these steps until you achieve full or acceptable signal strength. Once satisfied, you can mount the antenna permanently.

For surface mounting the GA™ 38 antenna, you will need:

A 3.2 mm (1/8 in) drill bit for pilot holes.
A 25 mm (1 in) drill bit or hole saw for the cable pass-through hole.
A Phillips screwdriver.
M4 screws (included, or of appropriate length if the included screws are too short).

Yes, the GA™ 38 antenna can be mounted on a standard 1-inch (outer diameter) threaded mast with 14 threads per inch (mast not included). The cable can be routed externally or through the mast.

When mounting on a mast, ensure not to overtighten the adapter on the mast. It is also recommended to fill the remaining space in the vertical cable slot with a marine sealant (optional) once the antenna is installed.

No, the below-deck mounting kit is supplied only with the white antenna models.

No, the GA™ 38 antenna cannot acquire signals through metal. It must be mounted under a fiberglass surface only for below-deck installation.

The safe distance from a compass to the Garmin GA™ 38 antenna is 114 mm (4.5 inches).

Yes, the Garmin GA™ 38 antenna is covered by Garmin’s standard limited warranty applicable to this accessory.
