FWIW

=A0=A0=A0=A0=A0=A0A coil will always lower the power handling
ability of an antenna.

Balderdash. The coil will evenly distribute heat that would otherwise
fry a lesser, non-coiled antenna.

Large coils lower it less than small coils, but

both large or small coils lower the antenna's

power rating. That's because of the resistance
of the coil. A fact of life, get used to it, it won't

change.
=A0

The resisitance of the "coil"?
I don't know what type antennas you have failed with in the past, but
you ought attend a keydown so you can se firsthand how your theory is
bunk in referring to those antennas specifically designed for power
capacitance.

=A0=A0=A0=A0=A0A coil's efficiency is directly related to it's

size. Big coils are more efficient than smaller

coils. A coil's efficiency

has nothing to do with how well it 'radiates',

unless the coil is an appreciable fraction of a

wave length, it radiates no better

than a length of wire of the same length.

Longer coils radiate better than shorter coils,

You're greatly cornfused, Paul. First, you claim:

A coil's efficiency has nothing to do with

how well it radiaites.

Then you self-contradict and claim

Longer coils radiate better than shorter coils.

Now, your words mean that the longer coil is more efficient (than
shorter), a direct contradiction to your claim that "the coil's
efficiency" has nothing to do with how it radiates. If a longer coil
radiates "better" than shorter coils, it is,,,,,taa daa...more
"efficient".

No sense taking it further with you until you rectify your
contradictions. Both claims can not be true.
