Designed to work \u003cstrong\u003ewithout a ground plane\u003c\/strong\u003e, it's ideal for GRP (fibreglass) and wooden hulls where a ground plane is not available. Covering 154–162.5 MHz at SWR ≤2:1 with a bandwidth of 8.6 MHz, it delivers 100W power handling and a gain of 0 dBd (2.15 dBi) with a 360° omnidirectional radiation pattern. The transformer DC-ground feed system provides inherent lightning protection. Supplied with a 5.5m white RG-58 C\/U coaxial cable directly connected, and featuring a 180° adjustable whip for flexible positioning. The high-quality white fibreglass conic whip with stainless steel hardware blends seamlessly with any vessel.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e100W power handling\u003c\/li\u003e\n\u003cli\u003eFrequency range: 154–162.5 MHz @ SWR ≤2:1\u003c\/li\u003e\n\u003cli\u003eBandwidth: 8.6 MHz @ SWR ≤2:1\u003c\/li\u003e\n\u003cli\u003eGain: 0 dBd \/ 2.15 dBi\u003c\/li\u003e\n\u003cli\u003eNo ground plane required — ideal for GRP \u0026amp; wooden hulls\u003c\/li\u003e\n\u003cli\u003eTransformer DC-ground feed — inherent lightning protection\u003c\/li\u003e\n\u003cli\u003e360° omnidirectional radiation pattern\u003c\/li\u003e\n\u003cli\u003eLinear vertical polarisation\u003c\/li\u003e\n\u003cli\u003e1\/2-wave base-loaded design\u003c\/li\u003e\n\u003cli\u003e180° inclination adjustable whip\u003c\/li\u003e\n\u003cli\u003eSupplied with 5.5m white RG-58 C\/U coax cable (directly connected)\u003c\/li\u003e\n\u003cli\u003eHigh-quality white fibreglass conic whip\u003c\/li\u003e\n\u003cli\u003eStainless steel hardware\u003c\/li\u003e\n\u003cli\u003eHeight: 1100mm\u003c\/li\u003e\n\u003cli\u003eWeight: 680g\u003c\/li\u003e\n\u003cli\u003eMade by Sirio\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: 1\/2-wave base-loaded marine VHF antenna\u003c\/li\u003e\n\u003cli\u003eFrequency range: 154–162.5 MHz @ SWR ≤2:1\u003c\/li\u003e\n\u003cli\u003eImpedance: 50Ω unbalanced\u003c\/li\u003e\n\u003cli\u003eRadiation (H-plane): 360° omnidirectional\u003c\/li\u003e\n\u003cli\u003eRadiation (E-plane): beamwidth at -3 dB = 60°\u003c\/li\u003e\n\u003cli\u003eRadiation angle: 23°\u003c\/li\u003e\n\u003cli\u003ePolarisation: Vertical\u003c\/li\u003e\n\u003cli\u003eGain: 0 dBd \/ 2.15 dBi\u003c\/li\u003e\n\u003cli\u003eBandwidth: 8.6 MHz @ SWR ≤2:1\u003c\/li\u003e\n\u003cli\u003eSWR at resonant frequency: ≤1.3:1\u003c\/li\u003e\n\u003cli\u003eMax power: 100W\u003c\/li\u003e\n\u003cli\u003eFeed system: Transformer DC-ground \/ base\u003c\/li\u003e\n\u003cli\u003eCable: 5.5m white RG-58 C\/U (directly connected)\u003c\/li\u003e\n\u003cli\u003eHeight: 1100mm\u003c\/li\u003e\n\u003cli\u003eWeight: 680g\u003c\/li\u003e\n\u003cli\u003eMaterials: Nylon, fibreglass, chromed brass\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIRIO","offers":[{"title":"Default Title","offer_id":57335685382488,"sku":"MOON-56-682","price":59.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/cruiser_vhf.png?v=1779283377","url":"https:\/\/kamsat.co.uk\/products\/sirio-cruiser","provider":"Kamsat","version":"1.0","type":"link"}
