EZNEC when modeled properly as solenoid or loading stub. Yea, the "other"
zero size coils don't show that, EZNEC confirms that.

As a data point, the results of modeling a coil as a lumped
inductor Vs a helical coil are NOT the same in EZNEC. EZNEC
disagrees with itself.

I am much more inclined to trust the helically modeled inductance
than the lumped inductance.

As Dr. Corum says: "Distributed theory encompasses lumped circuits
and always applies." In other words, the Distrubuted network model
is a superset of the lumped circuit model.
