The PC-controlled AT-200PC provides fully automatic, any mode antenna tuning across the entire HF range plus 6 meters at power levels to 250 watts. 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. There are no controls or indicators on the tuner itself -- all functions are controlled by software via a serial or USB connection from a PC.
