Palstar HF-Auto High Power HF and 6 Meter Automatic Antenna Tuner

摘要

The Palstar HF-Auto is a high-power automatic antenna tuner that covers a continuous frequency range from 1.8 to 54 MHz. This includes the 160 through 6 meter amateur bands, as well as Military Auxiliary Radio Service (MARS) and other frequencies outside the amateur bands. While most automatic tuners that we've seen adjust the tuning through the use of relay switched miniature fixed capacitors and inductors, the HF-Auto makes its adjustments through the use of a full-size rotary inductor and variable capacitor adjusted by precision stepper motors.
