Note
The AT-200ProII is a 250-watt automatic tuner. The AT-200ProII provides fully- and semi-automatic antenna tuning across the entire HF spectrum plus 6 meters, at power levels up to 250 watts (100W on 6m). 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 that of the built-in tuners on many transceivers.
While very similar, the "II" version introduced a few refinements:
– Improved LED Logic: The bar graphs were updated for better readability.
– Refined Algorithms: Faster and more accurate matching in difficult high-impedance scenarios.
– Firmware Tweaks: Better handling of the antenna switching logic via the front panel.
