Default Current through coils

You're expecting me to believe what you thought up in your head

What they saw with their own eyes is a mistake that you apparently
would never make. Roy tried to measure the delay through a loading
coil using the phase of a standing wave. As I understand what you
and Gene have said, that is impossible since the standing wave phase
doesn't contain any useful phase information.

This whole thing
boils down to an engineering question, anyway, which is, is it possible
to engineer a loading coil to be small enough at the lower end of the
HF spectrum so that it can be modeled using network analysis? Tom says
he can do it, and he's posted the results of his research efforts on
the web.


False, Tom has refused to use network analysis. That's the whole
problem. His lumped-circuit model assumes faster than light
propagation through every coil. His 3 nS through a 100 uH coil
is getting very close to faster than light speed.

Just today, Tom made a posting that indicates he still believes
that Func(kz)*Fun(wt) is the same thing as Func(kz +/- wt). My
measurements are the same as Tom's. Only one of the dozen or
so measurements made by everyone had the currents equal
at both ends.

Please look at Figure 3 at:

And please explain again how 1 amp is equal to 0.65 amps.
