Compatible with the FT-897, FT-857, FT-847, FT-100\/100D and FT-450, it automatically resonates the radiating element for the lowest SWR using control voltages sent via the coaxial cable — no manual tuning required. Covering 7 to 430MHz, it's an ideal all-in-one solution for mobile HF\/VHF\/UHF operation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAutomatic motorised tuning — resonates via coax control voltage from the transceiver\u003c\/li\u003e\n\u003cli\u003eCovers 7, 14, 21, 28, 50, 144 \u0026amp; 430MHz bands\u003c\/li\u003e\n\u003cli\u003e20% faster tuning speed than the ATAS-100\u003c\/li\u003e\n\u003cli\u003eSolid 'trombone' sliding sections for durability\u003c\/li\u003e\n\u003cli\u003eMounts directly onto a standard SO239 mobile antenna mount (not supplied)\u003c\/li\u003e\n\u003cli\u003eCompatible with FT-897, FT-857, FT-847, FT-100\/100D \u0026amp; FT-450\u003c\/li\u003e\n\u003cli\u003eOptional ATBK-100 VHF\/UHF antenna base kit available separately\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: 120W (A3J)\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 50Ω\u003c\/li\u003e\n\u003cli\u003eMatched SWR: \u0026lt;2.0:1 (with proper counterpoise)\u003c\/li\u003e\n\u003cli\u003eConnector: PL259 (for SO239 base)\u003c\/li\u003e\n\u003cli\u003eLength: 1.4–1.6m\u003c\/li\u003e\n\u003cli\u003eWeight: 900g\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The ATAS-120A is designed specifically for Yaesu transceivers with ATAS capability and is \u003cstrong\u003enot\u003c\/strong\u003e compatible with other transceiver brands or models.\u003c\/p\u003e","brand":"YAESU","offers":[{"title":"Default Title","offer_id":57522768150872,"sku":"MOON-12-550","price":269.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/12-550-4.jpg?v=1781605717","url":"https:\/\/kamsat.co.uk\/products\/yaesu-atas-120a-active-tuning-antenna-system","provider":"Kamsat","version":"1.0","type":"link"}
