More astonishing than that, Until the "gurus" put their finger on the coil,
or aquarium thermometer, or RF ammeter, or infrared scope and see that the
loading coil (in a typical quarter wave resonant whip) is heating up at the
bottom, being the reality that defies their "scientwific theories why it
shouldn't" - they will keep committing the same mental blunders over and
over.

What's next? There is less current in a wire (coil) where wire (coil) gets
hotter?
Let the games begin!

Thermometers don't lie, meters don't lie, even EZNEC shows it! So wasaaaaap?


If you're looking for an argument, you're looking in the wrong place.

Nobody denies the raw evidence, like the fact that some loading coils
get hotter at the bottom than at the top... and the fact that some other
coils don't (or nowhere near as much).

There are good explanations for everything you see. But the only valid
explanations are the ones that account for *all* the facts about *all*
types of loading coils.

The argument is specifically about Cecil's attempts to explain the
evidence, using his own particular ideas about "standing wave antennas".
He makes it kinda work for the cases he wants to think about, but in
other cases it gets things fundamentally wrong - and that isn't good
enough.
