Default I have question about R L Mathematics

Not sure where we have disagreement, do you disbelieve the 3,350ohms at

Yep. I am a heretic. You stated:
"I have measured the R at 3.85MHz, It is 3,350 ohms"
From where to where did you measure 3.35K, presumably with an ordinary
ohms-guesser?

If I short one end shield to center pin, and measure the other end
would that double impedance?
I'm going to find out.


It's like winding two turns on a toroid in opposite directions. The
inductances cancel and you get zero inductance. Replace the coax
cable with a single loop length of wire and see if it makes more
sense. Only turns that go AROUND the toroid in the same direction
provide useful inductances.
