Pray tell me then why I am incorrect. You can salvage the
answer from your own mind or even from a book.

When the air breaks down around an antenna it is because the antenna
is not in a state of equilibrium.

Define equilibrium as it pertains to an antenna. Until you do, it's
fairly hard to comment on the first statement.
If you have corona discharge from an antenna, it's usually due
to sharp points when using wire or a whip with a pointed tip.
Thats why they stick round balls on whips, flagpoles, etc..

When a dipole is replaced by a quad ala
a series circuit is replaced by a tank circuit it clearly shows that
the latter is more efficient.

What clearly shows this?
This is the statement which drew my comment.
The efficiency of a 1/2 WL dipole and a 1 WL loop are so close as
to be almost unmeasurable in the real world.
But you can take this even farther. Almost *any* size dipole
or loop will radiate most all of what is fed to it.
A 1/10 WL whip radiates almost all of the power applied to
it, same as a 1/4 WL, 1/2 WL, or whatever you want to try.
This not not conjecture. This is pretty much written in stone
after many years of testing.
Why you continue to ignore this simple fact boggles my mind.
So your statement is so far from reality I would be amiss
in my "talking head" duties if I did not comment.
Don't take my word for it. Ask anyone you can think of
that has a clue. They will tell you the same thing.

What it going to spoil your "full size performance from a
dinky radiator" picnic is not the radiator and it's abilities to be
an efficient radiator.
It's going to be actually feeding the power to such a small
radiator and not turning a large amount of RF to heat in the
process. No cheating letting the feed line be the antenna..
Look at "small" HF transmitting loops. Do you see any
using 22 gauge wire? I doubt it.
They will be using the fattest or widest strip of material
they can get their hands on.
There are other issues involved also in feeding such an
antenna. Never do these small loops equal the performance
of a full size antenna. They radiate enough to maybe let
you operate, and thats about it.



This was firmly proven in Quito.Maximum radiation
efficiency requires equilibrium. Period

Again, the change to quad loops at HCJB was to
avoid the sharp points of the dipoles, yagi's, or
whatever they were using. In the high alitudes of
Quito, HV breakdown at the tips was a serious problem.
The change had absolutely nothing to do with antenna
efficiency.
Not to mention that the whole idea of a loop being
more efficient than a dipole is totally wrong.
And I don't see how equilibrium has anything to
do with it, whatever you might mean by that silly "E"
word.
Anything else you are curious about?
BTW, no grabbing of books were needed to form
this response.
