Piedestal radar Garmin GMR 434/436 xHD3

This pedestal is specifically designed to be the essential mount for Garmin GMR 434 and GMR 436 radar antennas from the xHD3 series.

The package includes:

The GMR 434/436 xHD3 radar pedestal.The complete mounting hardware, including threaded rods, washers, nuts, and screws.
The Petrolatum primer, used for application on the threaded rods during assembly.

The following tools are typically required for pedestal installation:

A #2 Phillips screwdriver.
A 5 mm hex key.
A drill with a 15.0 mm (19/32 in) bit for mounting holes.
A drill with a 32 mm (1 1/4 in) bit if you need to route cables through the mounting surface.
A 17 mm (21/32 in) wrench and a torque wrench.
12 AWG (3.31 mm²) copper wire for radar housing grounding.
Marine sealant for waterproofing.

When choosing the mounting location, consider the following points:

The radar must be mounted out of reach of people, with the vertical beam above head height, at a minimum safety distance. It must be mounted high above the vessel's keel line, with minimal obstructions to the radar beam. The mounting surface must be flat, sturdy, and parallel to the vessel's waterline. The location must allow for power, grounding, and network connections.

Avoid mounting the radar near heat sources (exhausts, lights) or other electronic equipment/cables (maintain a minimum distance of 2 m from the radar beam path, 1 m from transmitting equipment and radio cables, and 2 m from SSB radios). GPS antennas must be positioned above or below the radar beam path.

Yes, this pedestal is designed to ensure reliable integration and optimal compatibility with Garmin marine networks, including Garmin BlueNet™ and Garmin Marine Network.

This pedestal is specifically designed for Garmin GMR 434 and 436 antennas from the xHD3 series.

With the radar pedestal, you will receive the following items:

The pedestal itself.The complete mounting hardware, including threaded rods, washers, nuts, and screws.A petrolatum primer.A mounting template.

Yes, this pedestal is designed to integrate reliably with the Garmin BlueNet or Garmin Marine Network.

For installing the radar pedestal, you will need the following tools:

A Phillips screwdriver size #2.A 5 mm Allen wrench.A drill with a 15.0 mm (19/32 in) bit.A 17 mm (21/32 in) wrench and a torque wrench.12 AWG (3.31 mm²) copper wire for grounding the radar housing.Marine sealant.

For optimal performance and safety, the radar must be installed while respecting several considerations:

It must be out of reach of people, with the vertical beam width above head height. It must be mounted 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. Avoid mounting it near heat sources (exhausts, lights) or at the same level as spreaders and mast cross-trees. GPS antennas must be either above or below the radar beam path.

If you drill a hole to pass power and network cables through the mounting surface (up to 32 mm or 1 1/4 in diameter), you must apply marine sealant to the hole after the cables are installed to ensure a watertight seal. Optional decorative cable glands can be used, but they do not provide waterproofing and also require the application of marine sealant.

Yes, it is possible to extend the power cable if necessary. However, you must use a wire section suitable for the extension length to ensure sufficient power supply and avoid radar malfunction. It is recommended to connect the power cable directly to the battery.

Yes, the radar must be grounded. A grounding cable (not included) must be connected to a water-grounding point, not to the battery's negative terminal.

If your radar model was supplied with a voltage converter, you must install it for the radar to function correctly. It is important not to reuse old Garmin voltage converters or third-party converters, as this could damage the radar. The converter requires an input voltage of 10 to 32 V DC.

Important precautions must be observed:

The radar transmits electromagnetic energy; ensure the radar beam is clear of any person before transmitting. Do not look directly at the antenna at close range when the radar is transmitting. Do not remove the inline fuse from the power cable. Installation by a qualified marine installer is recommended. This device contains no user-serviceable parts and should only be opened by a Garmin-certified technician. Always wear safety glasses, hearing protection, and a dust mask when drilling, cutting, or sanding.

The limited warranty does not apply in the following cases:

Cosmetic damage (scratches, nicks, dents).Consumable parts (batteries), unless the damage is due to a defect in materials or manufacturing.Damage caused by an accident, abuse, misuse, water, flooding, fire, or other natural disasters.Service performed by a service provider not authorized by Garmin.Product modified or altered without Garmin's written authorization.Product connected to power and/or data cables not supplied by Garmin.Connecting the power cable without the appropriate fuse in place voids the product warranty.

It is not recommended to print the mounting template yourself. It is preferable to use the template provided in the product box. If you decide to print it, you must strictly follow the instructions to ensure the scaling is set to 100% to avoid incorrect cutting on your boat's mounting surface.

To achieve optimal performance and prevent potential damage to the device or your vessel, installation by a qualified marine technician is recommended.
