The 4 ft array has a 1.8° horizontal beam width and a 23° vertical beam width, and the antenna weight for the 4 ft model is 5.5 kg (12.2 lb). This is the antenna array only; the radar pedestal is not included.\u003c\/p\u003e\u003cp\u003eOn board, this is the piece that physically rotates on the pedestal and shapes the radar beam. Radar controls and setup are handled from the chartplotter on the network, so the main job here is fit and mounting: the correct array length, clean mechanical attachment, and enough clearance for rotation on a hardtop, mast, or radar arch.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e4 ft open-array antenna for GMR xHD3 Series open-array radar pedestals (array only; pedestal not included)\u003c\/li\u003e\n\u003cli\u003eAntenna length: 132.7 cm (4 ft 4 1\/4 in.)\u003c\/li\u003e\n\u003cli\u003eBeam width (4 ft antenna): 1.8° horizontal, 23° vertical\u003c\/li\u003e\n\u003cli\u003eAntenna gain (4 ft antenna): 27 dB\u003c\/li\u003e\n\u003cli\u003eWater rating: IPX6\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -25 to 55°C (5 to 131°F)\u003c\/li\u003e\n\u003cli\u003eAntenna type: end-fed slotted waveguide\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis antenna is intended for GMR xHD3 Series open-array radar systems that use a separate pedestal and a bolt-on array. It is not a standalone radar scanner and it does not function by itself without the matching xHD3 pedestal and a chartplotter to control the radar.\u003c\/p\u003e\u003cp\u003eBefore ordering, confirm your pedestal is an xHD3 open-array model that supports the 4 ft antenna size, and confirm you have the mounting space for a rotating open array. Give the array room to spin without hitting antennas, outriggers, lights, or canvas.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eInstallation is a mechanical swap onto the pedestal. Use the correct hardware and tighten the hex screws to 70 lbf-in (5.83 lbf-ft) so the array is secured without damaging the mounting points.\u003c\/p\u003e\u003cp\u003eAfter the array is installed and the radar system is powered up, set the antenna size in the chartplotter radar installation menu so the system matches the 4 ft array. If the scanner is not aligned perfectly with the bow, set the front-of-boat offset so bearings line up with what you see on the water.\u003c\/p\u003e\u003ch6\u003eOn-board use\u003c\/h6\u003e\u003cp\u003eThis is a good match for boats that already run an xHD3 open-array pedestal and need a 4 ft array length for their mounting location. The 1.8° horizontal beam width helps keep close targets from blending together when you are working traffic, shorelines, and weather edges.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRinse salt and grime off the array after runs and check fasteners as part of your regular electronics inspection, especially after trailering or rough passages. Keep the rotation path clear and avoid tying lines, covers, or antennas where they can snag the moving array.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269262635189,"sku":"QBP429204","price":899.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1299757_qbp429204.jpg?v=1771542909","url":"https:\/\/www.qualityboatparts.com\/products\/qbp429204","provider":"Quality Boat Parts","version":"1.0","type":"link"}
