he AT-7000 provides automatic antenna tuning for your Icom IC-7000 (and some other Icom radios) across the entire HF range plus 6 meters. It will tune dipoles, verticals, Yagis or virtually any coax-fed antenna. It will match an amazing range of antennas and impedances, far greater than some other tuners you may have considered. The AT-7000 uses little power while tuning, and with its latching relays, uses essentially no power in standby.
