******A 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.


The coil will evenly dissipate heat that would otherwise be radiated as RF power
from 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.

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.


"Power capacitance"? Is that the newest entry in the "Amp Junkie's Dictionary of
RF Mythology"?


*****A 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".


You are once again demonstrating your ignorance of radio fundamentals. The
efficiency, or 'Q', of a coil has absolutely nothing to do with how well it
radiates because the purpose of a coil is to provide an inductance, not to
radiate a signal. In fact, coils with very high Q are very poor radiators.

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


The only contradiction here is between your ignorant misconceptions.
