   An 80-10 end-fed half-wave antenna can be a very good performing part of an HF station. But its performance depends heavily on a well-designed and carefully constructed 49:1 unun, which matches the long wire impedance to within tuning range of operation. But the perfor-mance of an end-fed antenna is also very dependent on height above ground.

   31 gru 2020 · My very basic tuner is working for its purpose, tuning EFHW cut to true half wave lengths and make them work when changing frequency between CW and SSB portion. I just introduced some minor features that I have not seen elsewhere in this design.
