Default Current across the antenna loading coil - from scratch

Roy Lewallen wrote:
Agreed, it's not quite stated as such. Here are some statements which
were made:

From your web page http://www.k3bu.us/loadingcoils.htm, in bold type:

"In summary:
The current in a typical loading coil in the shortened antennas drops
across the coil roughly corresponding to the segment of the radiator it
replaces."

By Cecil, on March 5, on this newsgroup:
The coil occupies roughly the same number
of degrees of the antenna as the wire it replaces.


Roy, maybe you need to learn the definition of "roughly".
It is certainly not "exactly" as you are clutching at straws
to imply. Why you need to change the definitions of words
is obvious from your flawed arguments. Exactly what is
it about "roughly" that you don't understand?

It's getting muddier and muddier just what you mean by "replace".


That meaning has never been in doubt. "Replace" has always
meant bringing the necessary signals back into phase so the
feedpoint impedance is purely resistive. You know perfectly
well that it has never been about physical length or radiation.
Those are just another two of your straw men. Your attempt
to muddy those waters has been going on for years including
your attempt to discredit the distributed network model in
favor of the lumped circuit model. Hint: The distributed
network model is a superset of the lumped circuit model.
If you succeed in discrediting the distributed network
model, you have automatically succeeded in discrediting
the lumped circuit model. It's a lose-lose proposition
for you.
