{"product_id":"garmin-antenne-radar-gmr-chirp-2104","title":"GMR CHIRP 2104 radar antenna, upper part","description":"\u003cp\u003e\n    The \u003cstrong\u003eGMR CHIRP 2104 radar antenna\u003c\/strong\u003e from Garmin, identified by SKU 010-01365-00, is the essential upper component of the \u003cstrong\u003eGMR Fantom™ Open Array Series\u003c\/strong\u003e open-array radar systems. Specifically designed for these platforms, it serves as the primary transmitter\/receiver element, integrating CHIRP technology for improved target detection and higher resolution. This component is critical for owners looking to replace an existing antenna or maintain optimal performance of their Fantom radar system, thereby extending the lifespan and efficiency of their high-end marine installation.\n\u003c\/p\u003e\n\n\u003ch3\u003eCHIRP Technology and Detection Precision\u003c\/h3\u003e\n\u003cp\u003e\n    The CHIRP (Compressed High-Intensity Radiated Pulse) technology embedded in the GMR CHIRP 2104 antenna broadcasts pulses across a range of frequencies, delivering a sharper radar image and better target separation compared to traditional pulse radars. This antenna is the core of the Fantom radar’s detection capability, ensuring resilience and precision essential for navigation. The radar beam has a vertical spread of 11.5° above and 11.5° below the radiating element, enabling effective coverage even on vessels with high bow angles at cruising speed. To optimize performance, the installation angle can be adjusted to direct the beam slightly toward the waterline at rest.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and Specific Installation\u003c\/h3\u003e\n\u003cp\u003e\n    The GMR CHIRP 2104 antenna is designed to integrate seamlessly with the GMR Fantom series pedestal. It requires precise alignment of the waveguide and tightening of captive hex bolts to a specified torque of 7.9 N·m (6 lbf·ft) to ensure secure attachment and system integrity. Garmin recommends installation by a qualified professional to guarantee optimal performance and safety. The pedestal must be mounted on a flat, sturdy surface, parallel to the vessel’s waterline, and at a sufficient height to minimize obstructions and avoid human exposure to the radar beam. Location considerations are critical, including keeping it away from heat sources (exhausts, lights), magnetic compasses (respect safety distance), and other transmitting equipment (minimum 1 m from VHF radios and antennas, 2 m from SSB radios).\n\u003c\/p\u003e\n\n\u003ch3\u003ePower Supply, Grounding, and Safety\u003c\/h3\u003e\n\u003cp\u003e\n    The GMR Fantom radar system to which this antenna connects requires a 10–32 Vdc power supply. Depending on the model, a voltage converter may be required or optional for better wind resistance. The power supply must include an inline 15 A fuse (integrated into the radar power cable) and, if a converter is used, a 30 A fuse between the converter and the battery. Proper grounding of the radar and converter (if applicable) using a 3.31 mm² (12 AWG) copper wire to a water ground is mandatory for safety and proper operation. It is critical to follow all safety instructions, including avoiding direct eye exposure to the antenna while it is transmitting and maintaining the minimum safety distance specified in the product’s technical specifications to prevent radiofrequency (RF) exposure. The device is intended as a navigation aid and contains no user-serviceable parts; servicing must be performed by a Garmin-certified technician, underscoring the importance of professional installation and maintenance.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":55859048677716,"sku":"010-01365-00","price":647.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01.jpg?v=1779189968","url":"https:\/\/skysat.fr\/en-us\/products\/garmin-gmr-chirp-2104-radar-antenna","provider":"Skysat","version":"1.0","type":"link"}
