The obvious issue is not what the radio sees... It's what can happen on the
other side of the transform.  Voltages and currents that no one seems to
care about as long as their radio sees 50 ohms.

Subject: [Elecraft] Matching resonant antennas

"A correspondent asked me why I needed to tune a resonant antenna."

Perhaps the question should have been "why may you need to match the
impedance of a resonant antenna".   The answer may be that not all resonant
antennas are 50 ohm.   Resonance only means that inductive and capacitive
reactance are equal magnitude. Resonance says nothing about the value of R.
