{"product_id":"garmin-antenne-radar-gmr-xhd3-4-pieds","title":"Garmin GMR xHD3 4' radar antenna","description":"\u003cp\u003e\n    Designed for offshore sailing and fishing, the Garmin GMR xHD3 4' radar antenna (ref. 010-02780-00) is the 4-foot open-array antenna used in advanced radar systems of the GMR xHD3 series, such as the GMR 434 xHD3. Part of this series, it incorporates Garmin’s latest platform technologies to deliver high-resolution imaging and accurate detection capabilities. This antenna model, integrated into GMR xHD3 systems, succeeds previous generations of GMR radars, offering improvements in image clarity and target discrimination, and natively integrates with Garmin BlueNet™ and Garmin Marine Network for seamless compatibility within the Garmin ecosystem.\n\u003c\/p\u003e\n\n\u003ch3\u003ePerformance and Technical Specifications\u003c\/h3\u003e\n\u003cp\u003e\n    The GMR 434 xHD3 radar system, equipped with this 1.22-meter (4-foot) antenna, delivers a transmission power of 4 kW and provides detection ranges from 20 meters to 72 nautical miles. With a horizontal beam width of 1.8 degrees and vertical beam width of 23 degrees, combined with rotation speeds of 24 or 48 RPM, it enables rapid and detailed target acquisition. The system is designed to operate in wind conditions up to 80 knots, with an increased capacity of 100 knots if an optional voltage converter is used. The GMR 434 xHD3 is rated IPX6 for water resistance and requires a 11–32 V DC power supply, consuming 18 W in standby mode and 55 W during normal transmission. The complete assembly (antenna and pedestal) weighs 27.6 kg.\n\u003c\/p\u003e\n\n\u003ch3\u003eAdvanced Marine Detection Features\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003ca href=\"\/en-ae\/garmin-antenne-radar-gmr-xHD3-4-pieds\"\u003eGarmin GMR 434 xHD3 radar\u003c\/a\u003e integrates key technologies for enhanced marine environment interpretation. Scan Averaging technology filters sea clutter and interference, improving target detection. True Echo Trails display historical boat movements, facilitating collision threat identification. Dual Range with overlay allows simultaneous display of two independent detection ranges on a compatible screen, with the option to overlay them on a chart. Specific modes such as Auto Bird Gain and Bird Mode Preset assist in locating surface birds, potential indicators of fish schools. Target size angular adjustment optimizes displayed object shapes, while Dynamic Auto Gain adapts gain levels to varying environments (harbor, coastal, offshore). The Dynamic Sea Filter automatically adjusts gain to manage sea clutter based on conditions. The system also supports MARPA target tracking (up to 30 targets with additional sensors) and features a configurable guard zone for intrusion alerts. Its silent open-array drive motor ensures discreet operation.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and Connectivity Considerations\u003c\/h3\u003e\n\u003cp\u003e\n    Integration of the \u003ca href=\"\/en-ae\/garmin-antenne-radar-gmr-xHD3-4-pieds\"\u003eGMR 434 xHD3\u003c\/a\u003e is via Garmin BlueNet™ or Garmin Marine Network. The system requires a 11–32 Vdc power supply. A 15 A inline fuse is mandatory, and a 30 A fuse is required if an optional voltage converter is used between the converter and the battery. Proper grounding to the marine ground is essential. For optimal performance and RF safety, the radar must be mounted above the vessel’s waterline, with the beam height above head level, and at a minimum specified safety distance to avoid radiofrequency exposure. Installation should be performed by a qualified marine technician to ensure compliance with mounting directives, prevent interference with navigation instruments such as magnetic compasses or GPS antennas, and ensure adequate watertight cable penetrations with marine sealant. Power and network cables must not be routed parallel to other cables to avoid interference.","brand":"Garmin","offers":[{"title":"","offer_id":55860408484180,"sku":"010-02780-00","price":614.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_0595bde4-6614-4351-b3a2-bbd943f09483.jpg?v=1779192919","url":"https:\/\/skysat.fr\/en-ae\/products\/garmin-gmr-xhd3-4-radar-antenna","provider":"Skysat","version":"1.0","type":"link"}
