Reg, if you would learn the Smith Chart, you would know
that is not true. :-) At self-resonance, the inductive
reactance cancels the capacitive reactance leaving a
pure resistance usually of a few thousand ohms. But I
agree with you that a purely resistive self-resonant
choke is not a bad thing.

======================================

Cec, I don't need a Smith Chart, and neither does anybody else, to
work out the resistance at resonance.

I don't think you quite know what you are doing with elementary
circuit analysis. The Smith Chart is giving you the wrong answer. The
resistance of a choke at HF at self resonance is in the order of a
megohm or more, not just a few thousand ohms.

By the way, what is the diameter and winding length of a USA pop
bottle.
