{"product_id":"garmin-gmr-18-xhd3-radome-radar-marin","title":"GMR™ 18 xHD3 Radome","description":"\u003cp\u003e\n    The Garmin GMR 18 xHD3 radome represents a compact and high-performance radar solution designed for vessels requiring reliable radar detection and seamless integration with Garmin navigation systems. This model belongs to the xHD3 series, offering significant improvements over previous generations such as the GMR 18 HD3, particularly in signal processing for better target separation and clearer radar imagery.\n\u003c\/p\u003e\n\n\u003ch3\u003eRadar Technology and Performance\u003c\/h3\u003e\n\u003cp\u003e\n    The GMR 18 xHD3 stands out for its optimized electromagnetic energy emission. Its vertical beam width is 12.5 degrees above and 12.5 degrees below the radiating element, totaling 25 degrees, enabling effective coverage even in rough sea conditions. This performance is critical for detecting targets at short and medium ranges, making this radome ideal for coastal navigation, precipitation detection, and collision avoidance. Compared to the GMR 24 xHD3, the GMR 18 xHD3 offers a more compact 18-inch format, suitable for mid-sized boats where space is a critical factor, while retaining the advantages of xHD3 processing.\n\u003c\/p\u003e\n\n\u003ch3\u003eAdvanced Integration and Connectivity\u003c\/h3\u003e\n\u003cp\u003e\n    Integration is a major strength of the GMR 18 xHD3 thanks to Garmin BlueNet™ network technology. This radome is fully compatible with Garmin BlueNet and Garmin Marine Network devices. For optimal performance and future update support, it is recommended to connect it to a Garmin BlueNet chartplotter or a Garmin BlueNet 20 switch using the supplied Garmin BlueNet cable. For older systems equipped only with Garmin Marine Network devices, connection is possible via the Garmin Marine Network adapter cable (part number 010-12531-01), ensuring installation versatility. This integration capability positions it as a strategic component for expanding or modernizing an existing Garmin navigation system.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Considerations and Reliability\u003c\/h3\u003e\n\u003cp\u003e\n    Installing the GMR 18 xHD3 requires careful attention to ensure optimal performance and safety. The radome must be mounted at an appropriate height so that the radar beam clears the head height and minimizes obstructions. Specific safety distances must be respected relative to magnetic compasses, GPS antennas, and other transmitting equipment (more than 2 m from the beam path for electronics, more than 1 m for transmitting equipment and radio cables, more than 2 m for SSB radios). The mounting process uses four M8 x 1.25 x 60 threaded rods for surface thicknesses of 5 to 30 mm, with a recommended tightening torque of 13.7 to 18.6 N·m. The electrical connection requires a power cable with an integrated fuse holder, and precise recommendations on wire gauge are provided for cable extensions (e.g., 16 AWG for 2 m, 12 AWG for 6 m). These technical details highlight the robust engineering and reliability expected from marine equipment in this category, comparable to the quality standards of competing radomes such as Raymarine or Furuno in the compact radar segment with advanced digital processing.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"18 inches","offer_id":55860424442196,"sku":"010-02841-00","price":1457.41,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_e9bb5232-9215-4a18-87a4-b1c88e43bf69.jpg?v=1779193184","url":"https:\/\/skysat.fr\/en-gb\/products\/garmin-gmr-18-xhd3-radome-marine-radar","provider":"Skysat","version":"1.0","type":"link"}
