Art -

The most important measure of an antenna is the amount of field
intensity
it
can produce at a given distance in a given direction, per watt of
applied
r-f power. So far you have written nothing specific about this for
the
"Unwin" antenna.

Note that a transmission line feeding a 20 dB series attenuator
attached
to
the input of a 100% efficient antenna will show very high return
loss
to
the
r-f source ( 40 dB plus the twice the cable loss). But that
antenna
system
will radiate little of the available EM energy, nonetheless.

Could you please comment on the measured or at least the calculated
RADIATION CHARACTERISTICS of your antenna, compared to a matched
1/2-wave
dipole at that frequency (or an isotropic radiator), and tell us
how
you
arrived at them?

If you can do that, and your results can be scientifically
duplicated
by
others, you will have removed the source of a lot of the skepticism
you
read
here and in your similar threads on eHam.net.

Otherwise it will be "more of the same," which (let us hope) is or
should
not be your goal.

RF

No.More of the same is not my goal nor is it to respond to every
request.
The mathematision or doctorrate type can do it solely by
mathematics.
The computor program is built on those mathematics. and a antenna
program
will ALWAYs produce radiators in equilibrium which means at an
angle.
Even without
a optimiser you can do it on Eznec but it would be laborious but it
can be done.
People are enamoured with the Yagi so thay always insert planar type
figures thus the
program which is designed around equilibrium. If the goal is small
efficient radiators then
equilibrium must be present starting with a full wavelength that can
then be placed in a small volume.
It is the smaller efficient radiators and arrays that I have pursued
since radiation per unit length is solely a measure
that correlates with resistivity and it is that where my conclusions
lie. Gain itself is a whole different matter
cannot show it's worth

in other words, he hasn't, he won't, and he doesn't care... therefore,
more
of the same handwaving and meaningless bafflegab. he doesn't have the
math
background to present his theory in any kind of a coherent form, nor
of
course could he ever measure his neutrino/carbon vortex crud because
it
doesn't exist, so he keeps going back to the same old crap... its not
even
funny any more, just sad.

David,
at this stage in life it would very difficult for me to go thru the
math from the start
in the exercise of adding a a radiator and a time varying field to a
Gaussian field
to show it is the same asMaxwell equation, very few of us are. But
when you come across a theorem
that makes sense to you it is gravy added when a mathematician comes
along to supply the mathematics
which you can follow in part. Then when antenna computor programs
supply the ingredients of such an analysis
which proves the same you have to get excited. When you then apply
what is revealed in such a trail and succeed in making a smaller
antenna that anybody has made you stop questioning what you have
found. As an aside, where do you view the atributes of an antenna with
near constant SWR reponse would find most use. I know most will jump
to dummy load but this I ask in serious form.

I already gave you the quote that shows that Gauss's Law is part of
Maxwell's equations already, you need no math for that. and since all
the
antenna design programs are based on Maxwell's equations they of course
comply with Gauss's law... nothing exciting there.

the only use for a constant swr is to keep modern transceivers, that
don't
have a tuner, happy. swr has no correlation to performance of an antenna
as
far as gain or f/b or takeoff angle, things that are important to antenna
design. i can take any antenna and give it a flat swr, there used to be
a
tuner on the market that did just that, until the league lab x-rayed it
and
found it was nothing but a dummy load potted in epoxy. the funny thing
is,
people liked it because it did exactly as it claimed, gave a perfect
match
across a wide frequency range... they didn't care that it turned a good
percentage of their power into heat. so air cooled dummy loads as
antennas
can work, as long as you don't have anything better to compare it to...
but
I do, so I don't want one.

David ,Gauss did a lot of work in his life time for which he is
recognised.
Are you saying that the "Gaussian law of static" was a prime mover of
Maxwells laws.
If this is so why does not Maxwells laws provide the role of particles
in radiation?
From my view point Gauss's contribution was supplied in other ways
that did not include the statics law but then I look forward to you
showing me where I am wrong

well, your point of view is wrong.

O.K. you sound like you have the facts in front of you so I have no
alternative to do some research on the matter.
You could have saved me a lot of work if you pointed to a book or
something but I will dig anyway.
I will be gone for a while to see if I can find what you are looking
at. But then you have a reputation for lying
so you may have nothing but bluster!
