Default Shortwave Radio Listener (SWL) Antennas -versus- Amateur Radio Antennas

Actually, tuning it "electrically" *is* tuning the antenna
*system* to resonance. When I vary my ladder-line length
to achieve system resonance, I am using my feedline as a
series tuning section. When one achieves a Z0-match with a
tuner or by other means, one is tuning the antenna system
to resonance which, in a near-lossless system, results in
near-conjugate match and near-maximum power transfer in
either direction (assuming the receiver input impedance
equals the Z0-match impedance).


This ever so helpful to the OP receiving antenna problem.

This was precipitated by the news group clown RHF who changed the
subject from "Antenna for shortwave reception" to the current "
Shortwave Radio Listener (SWL) Antennas -versus- Amateur Radio Antennas"

Good job Trolling jackass RHF.
