U20148 Used Palstar AT-Auto 1500W Automatic Antenna Tuner

The Palstar AT-Auto is a premium, high-power automatic antenna tuner engineered for amateur radio operators running legal-limit setups. Unlike relay-switched autotuners, the AT-Auto uses a continuously variable roller inductor and differential capacitor driven by precision stepper motors to achieve an accurate match across HF and 6 meters. With an integrated cross-needle meter, high-contrast digital display, and robust internal components, it provides effortless automatic tuning alongside classic Palstar durability.
