Unlike motorised ATAS antennas, the ATAS-25 uses a manual tuning system to resonate the radiating element for the lowest SWR — eliminating the need for expensive mono-band whip assemblies. It supports dual-frequency operation on HF or 50MHz combined with either 2m or 70cm (duplexer not supplied). Designed to mount directly onto a standard camera tripod, it's an excellent choice for portable, SOTA, POTA, or temporary field operation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManual tuning system — no mono-band whips required\u003c\/li\u003e\n\u003cli\u003eCovers 7, 14, 21, 28, 50, 144 \u0026amp; 430MHz bands\u003c\/li\u003e\n\u003cli\u003eDual-frequency operation: HF\/50MHz + 2m or 70cm (duplexer not supplied)\u003c\/li\u003e\n\u003cli\u003eMounts onto a standard camera tripod (not supplied) — ideal for portable use\u003c\/li\u003e\n\u003cli\u003eCompact for transport at just 0.6m, extends to 2.2m for operation\u003c\/li\u003e\n\u003cli\u003eSupplied with radiating elements, VHF\/UHF radial elements, radial wires, spare radial wire \u0026amp; Allen key\u003c\/li\u003e\n\u003cli\u003eNot recommended for permanent outdoor installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFrequency: 7 \/ 14 \/ 21 \/ 28 \/ 50 \/ 144 \/ 430MHz\u003c\/li\u003e\n\u003cli\u003eMax Input Power: 100W SSB\/CW, 50W AM\/FM (HF\/50MHz); 50W all modes (144\/430MHz)\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 50Ω\u003c\/li\u003e\n\u003cli\u003eMatched SWR: \u0026lt;2:1\u003c\/li\u003e\n\u003cli\u003eHeight: 2.2m (operational) \/ 0.6m (transport)\u003c\/li\u003e\n\u003cli\u003eWeight: 930g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YAESU","offers":[{"title":"Default Title","offer_id":57522840502616,"sku":"MOON-12-5501x","price":249.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/yaesu-atas-25-enl_pr4891_1.jpg?v=1781606174","url":"https:\/\/kamsat.co.uk\/products\/yaesu-atas-25-manual-active-tuning-antenna","provider":"Kamsat","version":"1.0","type":"link"}
