The GPS antenna 24xd has a diameter of 91.6 mm and a height of 49.5 mm. Its weight is 201 grams, making it compact and lightweight for easy installation on any type of boat.

Yes, the GPS 24xd antenna uses the standard NMEA 2000 protocol. It is therefore compatible with any multifunction display, chartplotter, or instrument certified for NMEA 2000, regardless of brand.

You have two main options for installation:

Surface mounting: You can directly attach it to a flat surface on the deck or roof. Mast mounting: It can be screwed onto a standard 1-inch diameter mast bracket (14 threads per inch), which is not included.

Thanks to its multi-band GNSS technology, the Garmin GPS 24xd antenna delivers improved positioning accuracy, typically less than 1 meter. It uses multiple satellite constellations (GPS, GLONASS, Galileo, BeiDou) for enhanced reliability.

The GPS antenna 24xd provides a fast refresh rate of 10 Hz. This means your position, speed over ground (SOG), and course over ground (COG) are updated 10 times per second, delivering a very smooth display of your movements on your screen.

Yes, the antenna is designed for the marine environment. It is certified IPX6 and IPX7, ensuring full protection against powerful water jets and temporary immersion in water up to 1 meter deep for 30 minutes.

For optimal performance, install the antenna in a location with a clear, unobstructed view of the sky in all directions. Avoid mounting it near metal structures, radars, or other antennas that could block or interfere with the satellite signal.

The antenna comes with a 6-metre (19 ft 8 in) NMEA 2000 drop cable.

Yes, one of the major advantages of the GPS 24xd is that it provides heading data (Vessel Heading), in addition to position, speed, and COG. This allows for more stable display on your chartplotter, even at low speed or when stationary.

The antenna is powered directly by the NMEA 2000 network. It does not require a separate power connection. The accepted operating voltage is 9 to 32 Vdc, which is standard for NMEA 2000 networks.

The typical power consumption of the GPS 24xd antenna is 150 mA at 12 Vdc. On the NMEA 2000 network, this corresponds to a Load Equivalency Number (LEN) of 3.

Yes, the antenna comes with hardware for the two main mounting types: a surface-mount bracket and a mast-mount adapter, including the required fasteners. The mast itself is not included.

The white model of the GPS 24xd antenna is designed to operate within a temperature range of -30°C to 80°C (-22°F to 176°F), ensuring reliability in extreme weather conditions.

No, installation is generally plug-and-play. Once connected to the powered NMEA 2000 network, the antenna will be automatically detected by compatible displays and will start transmitting positioning data. No initial configuration is required for basic operation.

The antenna transmits several essential data via NMEA 2000, including the most important ones:

129025: Position (fast update)
129026: Course Over Ground & Speed Over Ground (COG & SOG, fast update)
129029: Detailed GNSS position data
127250: Vessel heading
127257: Attitude data (roll, pitch)

The safety distance from a magnetic compass is very small, only 12.7 mm (0.5 inch). You can therefore install it near a compass without fear of significant magnetic interference.

The GPS 24xd antenna is multi-constellation, meaning it can receive signals from multiple satellite systems simultaneously for improved accuracy and reliability. It is compatible with:

GPS GLONASS Galileo BeiDou

Yes, as with any NMEA 2000 device, you will need a free NMEA 2000 T-connector on your backbone to connect the antenna’s drop cable and integrate it into your network.

The housing is made of high-strength plastic alloy and is fully sealed with gaskets. This material is selected for its durability, resistance to UV, salt, and impacts, ensuring a long lifespan even in harsh marine conditions.

No, this antenna is designed exclusively for an NMEA 2000 network. To connect it to a computer, you would need an NMEA 2000 to USB or NMEA 0183 gateway, which is a separate device.

The Garmin GPS 24xd NMEA 2000 is an all-in-one sensor combining a multi-constellation GPS/GNSS receiver with an integrated magnetic compass. It does not only provide position data (latitude/longitude): it also transmits heading (PGN 127250) and attitude (PGN 127257) data over the NMEA 2000 network. This enhances the functionality of your autopilot, radar overlay, and boat route display.

The Garmin GPS 24xd antenna transmits a wide range of NMEA 2000 PGNs, including:

Position and heading: 127250 (Vessel heading), 127257 (Attitude data), 129025 (Position, rapid update), 129026 (COG and SOG, rapid update). GNSS: 129029 (GNSS position data), 129539 (GNSS DOPs), 129540 (GNSS sats in view). System: 126992 (System time), 126993 (Heartbeat), 126996 (Product information). Magnetic variation: 127258 (Magnetic variation).

Yes, this is possible, but only if your boat has a fiberglass deck. The white model of the antenna comes with a dedicated under-deck mounting kit. The chosen location must provide an unobstructed view of the sky through the fiberglass, as the GPS signal does not pass through metallic materials. Follow the provided mounting instructions for correct installation.

The Garmin GPS 24xd antenna has a diameter of 91.6 mm and a height of 49.5 mm. It weighs 201 grams (7.1 oz). Its housing is made of high-strength plastic alloy, fully sealed for optimal waterproofing.

The Garmin GPS 24xd antenna comes with a 6 m (19 ft 8 in) NMEA 2000 drop cable. This cable is designed to connect directly to an included NMEA 2000 T-connector for integration into your existing network.

Yes, the Garmin GPS 24xd antenna is designed to connect to any standard NMEA 2000 network. It uses a supplied NMEA 2000 T-connector to tap into the network backbone. It is compatible with Garmin chartplotters and other brands' devices supporting the NMEA 2000 protocol. For optimal compatibility, ensure your NMEA 2000 network is properly powered and terminated.

Yes, this is quite possible. The antenna transmits standardized data via the NMEA 2000 protocol, making it compatible with any device capable of reading the PGNs it emits (position, heading, etc.). However, for compass calibration, if you are not using a compatible Garmin chartplotter, you will need to perform a basic manual calibration (by turning in a circle) instead of the menu-assisted calibration.

Compass calibration can be done in two ways:

Via a compatible Garmin chartplotter: Access the device menu (Settings > Communications > NMEA 2000 Setup > Device List), select the antenna, then 'Compass Cal.' and follow the on-screen instructions.

Basic calibration: If you do not have a Garmin chartplotter, you must perform a manual calibration by making two slow, tight circles at a constant speed (at least 6.4 km/h) in a calm water area, after powering on the antenna.

The safe distance from the boat's compass (compass-safe distance) is 12.7 mm (0.5 inch). This means the antenna can be installed very close to the compass without risk of magnetic interference, making placement easier.

Yes, the antenna can be mounted on a standard mast or pole with an outer diameter of 1 inch (25.4 mm) and a thread pitch of 14 threads per inch. A pole mounting adapter is included. You can route the cable outside or inside the pole. Ensure the location has a clear view of the sky.

If you lose the signal, you can use the antenna's 'Auto Locate' function. This option allows you to clear existing satellite data and force the antenna to acquire new data. This option is only available when the antenna has no position lock. You can also perform a factory reset via the antenna's configuration menu.

Yes, the Garmin GPS 24xd antenna is a high-sensitivity GNSS (Global Navigation Satellite System) receiver. It can receive signals from multiple satellite constellations, including the US GPS, Russian GLONASS, and European Galileo, improving position accuracy and reliability even in challenging conditions.

For installation, you will need the following tools:

A drillA 3.2 mm (1/8 in) bit for pilot holesA 25 mm (1 in) hole saw for cable routing in surface mountingA 19 mm (3/4 in) bit for cable routing through a poleA countersink bit for fiberglass surfaces (recommended)A screwdriver suitable for the supplied screwsMarine sealant (optional)

Yes, if you cannot mount the antenna in an ideal location for the magnetic compass, you can disable the magnetic heading data. To do this, perform a factory reset via the antenna's configuration menu. The antenna will then continue to provide Course Over Ground (COG) data via GPS.

No, the antenna comes with a 6-meter NMEA 2000 drop cable. If you need additional length, you will need to add an extension to your NMEA 2000 network while respecting the maximum cable length and network termination guidelines. It is also possible to install a shorter drop cable if required.

Absolutely. The Garmin GPS 24xd antenna is perfectly suited for sailboats. Its ability to provide precise heading data via the integrated compass is particularly useful for autopilot tuning, especially at low speeds. Additionally, the under-deck mounting (on fiberglass) is a discreet and aesthetic option for sailboats. Just ensure it has a clear view of the sky.
