Antena radar Garmin GMR xHD3 6"

Yes, installation of the Garmin GMR xHD3 6' radar antenna by a qualified marine installer is highly recommended. This is essential to ensure the best possible performance, avoid potential damage to the device or the vessel, and maintain safety. The process involves important safety considerations and precise technical steps.

The Garmin GMR xHD3 6' radar antenna is designed to integrate with the Garmin BlueNet™ network or the Garmin Marine Network, ensuring seamless communication with other compatible devices in your navigation system.

The GMR xHD3 6' radar antenna requires a 10 to 32 V DC power supply. Depending on the model, a voltage converter may be included and must be used for correct operation. Ensure the appropriate fuses (a 15 A fuse in the radar power cable and a 30 A fuse if a voltage converter is used) are installed to prevent damage or fire risk.

When choosing the mounting location for the radar antenna, several factors must be considered:

The radar must be mounted out of reach of people, with the vertical beam width above head height. It must be installed high above the vessel's keel line, with minimal obstruction to the radar beam. The mounting surface must be flat, parallel to the vessel's waterline, and sufficiently robust to support the radar's weight. Avoid mounting it near heat sources (exhausts, lights) or at the same height as horizontal spreaders. It must be kept away from other electronic equipment and cables (more than 2 m from the beam path for electronics, more than 1 m for transmission equipment, and more than 2 m from HF radios). GPS antennas must be positioned either above or below the radar beam path.

No, the device contains no user-serviceable parts. The unit must only be opened by a Garmin authorized service technician. Opening the unit by anyone other than a Garmin authorized technician will void the product warranty.

No, the ground cable is not included with the GMR xHD3 6' radar antenna. You will need to obtain a 3.31 mm² (12 AWG) copper wire for this connection. It is essential to connect the radar housing (and the voltage converter, if applicable) to a water ground, not to the battery's negative terminal.

The Garmin GMR xHD3 6' radar antenna must be used solely as a navigation aid. It is not designed for applications requiring precise measurements, directions, distances, locations, or topographies.

The Garmin GMR xHD3 6' open-array radar antenna is a radar system from the GMR xHD3 series. It is designed to provide precise navigation and advanced target detection at sea, thereby optimizing the safety and efficiency of your movements.

The GMR xHD3 6' radar antenna offers several advantages for marine navigation:

Accurate detection: It enables clear and reliable target identification, even in challenging conditions.Network integration: It integrates seamlessly with Garmin BlueNet or Garmin Marine Network for a smooth user experience.Advanced performance: Designed for optimized navigation and improved awareness of the marine environment.

The product includes the following items to facilitate the mounting of the base and antenna:

Mounting template. Primer (Petrolatum Primer). Plastic shoulder washers. Threaded rods. Nuts. Flat washers and lock washers. Hex head screws for antenna attachment.

The ground cable is not included with the GMR xHD3 6' radar antenna. You will need to purchase a 3.31 mm² (12 AWG) copper wire for grounding the radar housing.

Yes, installation of the GMR xHD3 6' radar antenna by a qualified marine installer is strongly recommended. Incorrect installation can result in injury, damage to the vessel or the device, or poor product performance. Furthermore, opening the device by anyone other than a Garmin-authorized service technician will void the warranty.

For installing the GMR xHD3 6' radar antenna, you will need the following tools:

A Phillips screwdriver size #2.
A 5 mm and a 6 mm Allen key.
A drill with 15.0 mm (19/32 in) and 32 mm (1 1/4 in) drill bits.
A 17 mm (21/32 in) wrench and a torque wrench.
A 3.31 mm² (12 AWG) copper wire for grounding.
Marine sealant.

When choosing the mounting location, it is essential to consider the following points:

The radar must be mounted out of reach of people, with the vertical beam width above head height. It must be installed high above the vessel's keel line, with minimal obstruction of the radar beam. The mounting surface must be flat, sturdy, and parallel to the vessel's waterline. The radar must be kept away from heat sources, magnetic compasses (respect the compass safety distance), and other electronic equipment or cables (at least 2 m from the radar beam path). GPS antennas must be located above or below the radar beam path. Avoid mounting the radar within 1 m (40 in) of any transmitting equipment or cables carrying radio signals (VHF), and within 2 m (6.5 ft) of SSB radios.

The radar housing must be grounded. The ground cable is not included and must be connected to a dedicated underwater grounding point, not to the battery's negative terminal. A 3.31 mm² (12 AWG) copper wire is recommended for this connection.

During wiring, it is critical to follow these precautions:

Apply marine sealant around every cable pass-through hole to ensure perfect watertightness. Use appropriate cable ties, fastenings, and sealant to secure cables along their route. Avoid running cables near moving objects, high-heat sources, or through doors and bilge areas. Do not run network and power cables parallel to other cables (radio antenna lines or power lines) to prevent interference. If unavoidable, cables must be shielded with a metal conduit or EMI shielding. Install the power cable as close as possible to the battery source.

The GMR xHD3 6' radar antenna requires an input voltage of 10 to 32 VDC. If a voltage converter is used, it also requires an input voltage of 10 to 32 VDC.

If your model was delivered with a voltage converter, you must install it for the radar to function correctly. It is important to use only the converter included with the radar or a compatible converter purchased from Garmin or an authorized dealer, as using another converter may damage the radar. Even if some radar models do not require a voltage converter, using one with these models allows them to withstand stronger winds.

The GMR xHD3 6' radar antenna is designed to integrate seamlessly with Garmin BlueNet™ and Garmin Marine Network marine networks. This ensures smooth communication with other compatible devices in your Garmin navigation system.

Several actions may void the warranty of your GMR xHD3 6' radar antenna:

Opening the device by anyone other than a technician authorized by Garmin.Connecting the power cable without the appropriate fuse in place, as specified in the product documentation.Using a voltage converter other than the one included with the radar or a correct converter purchased from Garmin or an authorized dealer.
