Detailed description

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

Integration and Compatibility

This antenna uses a standard BNC connector to connect to the dedicated "ANTENNA" or "EXT GPS" ports on compatible Garmin chartplotters. Its broad compatibility makes it an essential accessory for navigators looking to strengthen their existing GPS system or add positioning capability to devices lacking it or benefiting from improved signal reception. It serves as an external alternative to internal GPS modules, offering superior installation flexibility to ensure clear sky visibility.

Versatile Mounting Options

The Garmin GA™ 38 offers multiple mounting options to suit various vessel configurations. It can be surface-mounted using the included surface-mount bracket, or installed on a standard 1-inch threaded mast (not included) via the mast-mount adapter. For discreet installations or when aesthetics are critical, a below-deck mounting kit is also available (supplied with white antenna models only), allowing the antenna to operate effectively through non-metallic fiberglass surfaces. Its compact design (91.6 × 49.5 mm) and lightweight (201 g) facilitate integration.

Robust Design for Marine Environments

Constructed from a high-strength, fully waterproof plastic alloy, the Garmin GA™ 38 is designed to withstand the harshest marine conditions. Its IEC 60529 IPX7 waterproof rating ensures protection against temporary immersion, guaranteeing reliable performance even in heavy spray or accidental submersion. It operates within a temperature range of -30° to 80°C (white model) and maintains a 114 mm safety distance from compasses, minimizing interference with other navigation equipment.

« GPS/GLONASS precision optimization for Garmin systems »

The Garmin GA™ 38 antenna is a reliable external solution essential for optimizing GPS and GLONASS reception on vessels equipped with Garmin electronics. Its ability to simultaneously capture signals from both satellite systems provides enhanced positioning accuracy, crucial for coastal and offshore navigation. Integration via a standard BNC connector simplifies connection to chartplotters, VHF radios, and compatible AIS systems, ensuring broad compatibility within the Garmin ecosystem.

From an installation perspective, the GA™ 38 offers notable flexibility. Surface, mast, or under-deck mounting options (for fiberglass hulls) allow positioning the antenna in the ideal location for clear sky visibility, minimizing structural interference from the boat. This flexibility is a major advantage in installations where the internal antenna of a primary device would be compromised. Its robustness, evidenced by a high-strength plastic alloy construction and IPX7 waterproofing, ensures durability against harsh marine environments, from extreme temperatures to spray. For optimal performance, it is imperative to maintain safe distances from radars and VHF antennas to avoid electromagnetic interference.

What is the Garmin GA™ 38 antenna and what is it used for?

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.

Which positioning technologies does the Garmin GA™ 38 antenna use?

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

What are the dimensions and weight of the Garmin GA™ 38 antenna?

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).

What is the operating temperature range of the GA™ 38 antenna?

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

What is the waterproof rating of the Garmin GA™ 38 antenna?

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

What material is the Garmin GA™ 38 antenna housing made of?

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

Can the GA™ 38 antenna be damaged by magnetic fields?

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

Which devices is the Garmin GA™ 38 antenna compatible with?

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

Near known ferrous metal objects, such as a toolbox or 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.

How to test the mounting location before permanently securing the antenna?

To test the mounting location:

Temporarily secure the antenna at the chosen location and verify its proper operation. If you encounter 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 permanently mount the antenna.
