Don't know if this whole thing is a troll or just someone's idea of "fun"
but the definition of a resonant antenna is well known and not a subject
for speculation or debate.

An antenna is resonant at a specified frequency if its driving point
impedance is purely real.

I suggest that any further discussion in this area go private . . .
