Tom, have you read what Dr. Corum had to say about that on
page 8 of http://www.ttr.com/corum/index.htm? Here's a partial
quote: "The problem has been that many experimenters working
self-resonant helices have pursued the concept of coil self-
capacitance without really understanding where the notion
comes from or why it was ever invoked by engineers."

Cecil,

You keep trying to drag something from a self-resonant helice into a
loading coil discussion.

The two are nearly at opposite extremes in behavior, but even at that
the self-resonant helice can be analyzed with standar L/C analysis.

It's just another way to analyze things, and it's just one way of doing
it.
