I think you're using the word "real" where I would use "RMS" and
"complex" where I would use "reactive", but aside from that, ok.

Correct, in that specific hypothetical example, which the FCC couldn't
care less about. I was referring to the RMS E and I at the output of
the transmitter, which is what the FCC will be interested in. I'm
sure if you try to slip your hypothetical stuff by them, they will
slap on a 50 ohm load, retune to whatever your anode E and I meters
said beforehand, and quickly fill out your citation. When you go to
court, I'm sure the judge won't care any more than the FCC did.
