Does an antenna-tuner actually heat up?

Yada, just ignore whatever you don't like.


A tuner has a current flowing through it and it has a resistance so it
to heat up. But that's not the question. Resistive loss is independent
of the frequency.


The question is, .. are the other additional physics effects playing
here that will cause it to "ventilate" energy?
