Default Current through coils

Food for thought.

At this moment in time it seems Cecil is claiming an inductor acts like
so many electrical degrees, but of course at any moment another waffle
might pops out of the Texas toaster and change everything.

Let's assume we have a mobile antenna that is 25 electrical degrees
tall. Now following the logic a loading coil acts like a transmission
line, we have a 65-degree loading coil.

Following the same twisted logic, since the loading inductor is
65-degrees long, we should be able the move it anywhere in the antenna
without changing antenna tuning.

Our 75 meter antenna should also work on 25 meters as a 3/4 wave
antenna, and on 37.5 meters as a half-wave.

Of course we all know it doesn't behave anything close to this way.

Wouldn't it be nice if Cecil could show us all how to predict the
resoances of an antenna based on his idea that loading inductor acts
like a transmission line? Where are the design equations we can all
use?
