{"product_id":"garmin-radar-gmr-xhd3-6","title":"Garmin GMR xHD3 6' radar antenna","description":"\u003cp\u003e\n    The Garmin GMR xHD3 6' radar antenna is an advanced solution for navigation and target detection. Part of the GMR xHD3 series, this open-array 6-foot antenna is designed for navigators requiring increased precision and optimized radar performance. It natively integrates with Garmin ecosystems via Garmin BlueNet or Garmin Marine Network, ensuring seamless compatibility and synergy with other Garmin instruments. Its design focuses on reliability and technical performance, making it a robust choice for vessels requiring detection range and clarity superior to compact radomes, without the bulk of larger open arrays.\n\u003c\/p\u003e\n\n\u003ch3\u003ePrecision and technical performance\u003c\/h3\u003e\n\u003cp\u003e\n    The GMR xHD3 6' offers notable target detection precision thanks to its open-array design. The vertical radar beam propagates with a width of 11.5° above and 11.5° below the radiating element, enabling extended coverage. For vessels with more pronounced bow angles at cruising speed, the installation angle can be adjusted to slightly orient the beam toward the waterline at rest, using shims if necessary. A high installation, above the vessel's keel line and with minimal obstacles, maximizes detection range and minimizes blind sectors or false echoes.\n\u003c\/p\u003e\n\n\u003ch3\u003eNetwork integration and installation\u003c\/h3\u003e\n\u003cp\u003e\n    This radar antenna requires a 10 to 32 VDC power supply, with the option for direct connection to the battery (11 to 32 VDC for some models without an included voltage converter). A 15 A inline fuse is integrated into the radar power cable, and an additional 30 A fuse is required between the voltage converter (if used) and the battery. Integration into the Garmin network is done via Garmin BlueNet or Garmin Marine Network. The installation process, recommended to be performed by a qualified professional, involves drilling 15 mm mounting holes and a 32 mm cable pass-through hole if necessary. The kit includes the mounting template, Petrolatum Primer primer, plastic shoulder washers, threaded studs, nuts, and washers for base mounting, as well as hex screws, spring washers, and flat washers for antenna attachment. Note that the ground cable is not provided and requires a 3.31 mm² (12 AWG) copper wire.\n\u003c\/p\u003e\n\n\u003ch3\u003ePhysical installation optimization\u003c\/h3\u003e\n\u003cp\u003e\n    For optimal performance and increased safety, installation of the GMR xHD3 6' must account for several factors. The radar must be mounted out of reach of people, with the vertical beam above head height, and at a minimum safety distance specified to avoid radiofrequency exposure. It must be kept away from heat sources (chimneys, lights) and positioned at a different level than horizontal spreaders. To avoid interference, the radar must be installed more than 2 m (6.5 ft) from other electronic equipment and cables, more than 1 m (40 in) from transmitters and radio cables (VHF), and more than 2 m (6.5 ft) from SSB radios. GPS antennas must be positioned either above or below the radar beam path. These considerations ensure optimal operation of the GMR xHD3 6' and safety on board.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"6 feet","offer_id":55860410188116,"sku":"010-02780-10","price":897.41,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_62b80c98-123a-4f6e-9c58-c07e648a7828.jpg?v=1779192941","url":"https:\/\/skysat.fr\/en-gb\/products\/garmin-gmr-xhd3-6-radar-antenna","provider":"Skysat","version":"1.0","type":"link"}
