With 100W power handling, a gain of 3 dB, and a VSWR of \u0026lt;1.5:1, it delivers solid omnidirectional performance straight out of the box with no tuning required. The GRP (fibreglass) outer shell provides excellent weather and UV resistance for long-term outdoor installation. Mast mounting brackets and radials are included. Mounts on masts of 30–62mm diameter and is rated to withstand wind velocities of 60 m\/s.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePre-tuned for 4-metre band (70–72 MHz) — no tuning required\u003c\/li\u003e\n\u003cli\u003e100W power handling\u003c\/li\u003e\n\u003cli\u003eGain: 3 dB\u003c\/li\u003e\n\u003cli\u003eVSWR: \u0026lt;1.5:1\u003c\/li\u003e\n\u003cli\u003e1\/2-wave design\u003c\/li\u003e\n\u003cli\u003eGRP (fibreglass) outer shell — fully weatherproofed\u003c\/li\u003e\n\u003cli\u003eSO-239 (UHF-Female) connector, 50Ω impedance\u003c\/li\u003e\n\u003cli\u003eMast mounting brackets \u0026amp; radials included\u003c\/li\u003e\n\u003cli\u003eMast diameter: 30–62mm\u003c\/li\u003e\n\u003cli\u003eRated wind velocity: 60 m\/s\u003c\/li\u003e\n\u003cli\u003eLength: 1.5m\u003c\/li\u003e\n\u003cli\u003eWeight: 0.7kg\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: 1\/2-wave fibreglass base antenna\u003c\/li\u003e\n\u003cli\u003eFrequency: 70–72 MHz (4-metre band)\u003c\/li\u003e\n\u003cli\u003eGain: 3 dB\u003c\/li\u003e\n\u003cli\u003eMax power: 100W\u003c\/li\u003e\n\u003cli\u003eImpedance: 50Ω\u003c\/li\u003e\n\u003cli\u003eVSWR: \u0026lt;1.5:1\u003c\/li\u003e\n\u003cli\u003eConnector: SO-239 (UHF-Female)\u003c\/li\u003e\n\u003cli\u003eMast diameter: 30–62mm\u003c\/li\u003e\n\u003cli\u003eWind rating: 60 m\/s\u003c\/li\u003e\n\u003cli\u003eLength: 1.5m\u003c\/li\u003e\n\u003cli\u003eWeight: 0.7kg\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MOONRAKER","offers":[{"title":"Default Title","offer_id":57373249077592,"sku":"MOON-11-226","price":49.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/sqbm412-2_1.jpg?v=1779788334","url":"https:\/\/kamsat.co.uk\/products\/sqbm412-70mhz","provider":"Kamsat","version":"1.0","type":"link"}
