because contrary to what those male enhancement product adds tell you, size
doesn't matter.

for the word volume. Pertinent factors are wave length of frequency in
The problem here is that amateur radio is wellded to the yagi design
which is not one of equilibrium

WAIT JUST ONE GOSH DARN MINUTE! you have said in the past that the simple
half wave dipole WAS a prefect example of equilibrium! NOW it isn't???
have you had a new revelation while i had your old email address plonked??

David,
You admit to not understanding the term "equilibrium" so what do you
care what I say and in what content.
If you consider a half wave dipole as being in equilibrium you have to
consider the electrical circuit
consisting of a capacitance from the antenna to ground or the route
thru the center of of the radiator, both of thes circuits
can be considered as being in equilibrium. However, on this newsgroup
a fractional wavelength radiator is considered as an open circuit for
some reason and thus under those circumstances the half wave dipole is
not in equilibrium.
Now your views on radiation is all over the place so it is very hard
for me to determine the context of what you say.
Art

Long before we rode our dinosaurs to club meetings the bright lights
had completely agreed that the strength of radio signals at far off
places was a function of the integral of i·dl where dl is the bigness
of the aerial. Maybe it's in Sears and Zemansky. I dunno . . nor do I
really care.
