It is available in 18 inch and 24 inch radome sizes and carries an IPX7 water rating.\u003c\/p\u003e\u003cp\u003eOn the screen, you can run split-screen dual range, overlay radar on your chart, and use features like scan averaging and target-size processing to keep returns readable when sea clutter and interference start to build. Rotation speeds up to 60 rpm help keep target updates moving fast, which matters when you are threading a busy channel or tracking a squall line.\u003c\/p\u003e\u003cp\u003eAnglers can use bird detection with Auto Bird Gain, and skippers who want tracking tools can use MARPA target tracking for up to 30 targets when a suitable heading sensor is on the system. This radar is a good match for boats already built around a Garmin networked helm and for crews who want one antenna to cover close-quarters work and longer-range awareness.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e4 kW transmit power with 48 nm maximum range and 20 m minimum range\u003c\/li\u003e\n\u003cli\u003e11 to 32 V DC input for 12 V and 24 V systems\u003c\/li\u003e\n\u003cli\u003eTypical power draw: 15 W standby and 40 W transmitting (normal mode)\u003c\/li\u003e\n\u003cli\u003eUp to 60 rpm antenna rotation for quicker target updates\u003c\/li\u003e\n\u003cli\u003eSplit-screen dual range plus radar overlay on compatible displays\u003c\/li\u003e\n\u003cli\u003eScan averaging, dynamic auto gain, and dynamic sea filter to manage clutter as conditions change\u003c\/li\u003e\n\u003cli\u003eTrue echo trails for motion history on targets\u003c\/li\u003e\n\u003cli\u003eAuto Bird Gain and bird detection for finding surface activity\u003c\/li\u003e\n\u003cli\u003eMARPA target tracking for up to 30 targets (requires an appropriate heading sensor)\u003c\/li\u003e\n\u003cli\u003eGuard zone alarms and range\/bearing cues for quick situational checks\u003c\/li\u003e\n\u003cli\u003eIPX7 water rating for incidental water exposure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis radar dome is offered in multiple configurations based on radome size.\u003c\/p\u003e\u003cp\u003eThe size option changes the physical footprint, antenna length, and horizontal beam width. Core electrical specs and feature set remain the same across the 18 inch and 24 inch versions, including 4 kW output, 48 nm maximum range, and 11 to 32 V DC power input.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e010-02841-00: Size 18\" (20\" x 9.8\", 7.0 kg, 17\" antenna length, 5.2° horizontal beam width).

The base should be flat and parallel to the vessel waterline, with structure underneath that can support the radar weight and vibration loads. On some hardtops, raising the radar helps keep the roof edge from shading the beam.\u003c\/p\u003e\u003cp\u003eKeep clear of magnetic compasses by maintaining at least 1.1 m separation for the 18 inch model and 0.95 m for the 24 inch model. Route cables with chafe protection, seal deck penetrations with marine sealant, and secure the run so it will not work loose over time.\u003c\/p\u003e\u003ch6\u003eElectrical and network integration\u003c\/h6\u003e\u003cp\u003ePower is 11 to 32 V DC, with a typical 7.5 A fuse requirement on the supply. Standby draw is 15 W, and typical transmitting draw in normal mode is 40 W, so the radar can stay available without heavily loading the house system.\u003c\/p\u003e\u003cp\u003eNetwork connection is through the Garmin Marine Network to a compatible chartplotter or MFD. Radar overlay and MARPA functions require appropriate sensors on the boat, and dual radar support allows redundancy when multiple radar sources are installed.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRinse the radome with fresh water after salt use and keep the outer surface free of heavy grime that can hold salt. Periodically check mounting fasteners, cable condition, and strain relief points, especially after rough-weather runs or long trailering days.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"18\"","offer_id":52270727921845,"sku":"QBP273350-V1","price":1999.99,"currency_code":"USD","in_stock":false},{"title":"24\"","offer_id":52270727954613,"sku":"QBP273350-V2","price":2799.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1303752_qbp273350.jpg?v=1771550659","url":"https:\/\/www.qualityboatparts.com\/products\/qbp273350","provider":"Quality Boat Parts","version":"1.0","type":"link"}
