Hi Robert,

50 years ago they said Electricity would be so easy to produce they
would pay us to use it. They ignored Hiroshima and discovered
Chernobyl.

40 years ago they said DNA and genetics would allow us to design our
own babies. They ignored Thalidomide and discovered Dolly the sheep
that died before her time.

30 years ago they invented modeling software that would allow us to
create the Gaussian dipole (or whatever) and discovered every dipole
that came before it performed better.

Nearly 20 years ago Johnny Carson retired and we are still getting
jokes.

Not nearly 10 years ago with the Dow at 11658 and a budget surplus at
230 billion, the Republicans promised prosperity was around the corner
and their voters are now living in cardboard boxes with the Dow at
12176 and the national debt up 50%.

Scaling of antennas is clearly
possible, despite of what the Chu-Harrington limit states ( or to be
fair, by applying them in a new way ).

But you don't know how, and have never seen one either.

Hi Richard,

I have a pair of computer speakers sitting on my desk that completely out
perform the so called ultimate hi-fi floor mounted tower system speakers I
bought 35 years ago for the equivalent of several thousand dollars in
today's money. The old speakers still work just fine but the audio experts
have learned how to squeeze that performance out of a speaker that old audio
theory predicted couldn't possibly work. Just how does a 3 inch speaker in a
cabinet the size of a couple of books manage to produce notes from 20 Hz -
20 kHz? To be fair, the small speakers can't fill a room with sound in the
same smooth way that a larger speaker cabinet can, but for everyday use in a
small modern house or apartment they are more than adequate for the majority
of people.

It seems to me that Art and others are pursuing a similar path at RF. The
aim being to produce an antenna that punches out a signal from a physically
small area. It may not perform quite as well as a full size half or full
wavelength antenna, but it will work well enough for most people with small
gardens or limited real estate for an antenna farm.

Clearly there are considerable differences in dealing with sound waves and
RF but I believe that a principle has been established that it is possible
to 'simulate' the performance of a larger system using physically small
components. Art may not be the first to get there, but he seems to be having
a damn good try and someone, somewhere will eventually succeed.

Mike,
I am already there. Regardless of the confidence I have in my own
findings
I have cinsented for a stanger in another state to test it in a way he
feels comfortable with.
I might also remind you that the antennas are Small full wave antennas
which vastly different
to electrically small antennas that is often written about by many
including Chu!
As far as equilibrium goes it is adviseable to go back a few hundred
years when
scientists observed a static bubble and wove a mathematical response
to their puzzle.
Most people on this thread do not have a thorough understanding of the
masters laws
which are derived around the term equilibrium. Many were agast at the
idea of adding a time variable
to Gaussian law since the correllation between a closed boundary and
equilibrium
was to complicated for them to understand. Then there were those who
disliked the idea of static particles
being electrons and wanted me to state it was a part of an electron
that passed in a straight line thru the atmosphere.
These people will go into a state of shock if I called partices by the
name of neutrinos no less.
All because of the stance they have taken that all is known about
radiation. It was the small step
that I took that scientists have been looking for for years when they
began
to lose faith in classical physics snd the laws of Newton and turned
to address numourous new sciences
for answers.Now they may retreat and bind themselves more firmly to
the classical science and the pursuit of a universal law
which Einstein seached so hard for.
As far as 'all is known' older people hate change with a vengence and
will fight to the death against it with
the short time they have left on this earth . Fortunately the younger
generation always comes along with an
inquisitiveness that cannot be suppressed and are willing to rebuild
where past structures disappear below the sands.
Small FULL WAVE radiators are here now where a single element can
supply the same gain as a planar array.
Single elements that can be made with two degrees of freedom that can
also be stacked to add an extra
degree of freedom for the smallest WiFi device. I now await the
standard comments that comes along after each of my patents,
I new that already! It is really not all that special! It was me who
gave you the idea in the first place.
Anybody can get a patent ! That was already known and invented before.
It is not my fault that people didn't make it earlier!
What use is it? We already have good antennas!
Yup. Small full wave antennas are now here that can cover all
frequencies, not just all bands!
Moxon was just a tad to late to see the new antennas for small gardens
in the U.K.
