I dont have EZNEC, But I will trust you if you care to model a 1/4wl
monopole and compare it to an 1/8wl monople operating against a
perfect counterpoise. Fine enginneer that Art is he should have no
trouble in calculating field intensity at a receiving antenna 1 mile
away. I have total respect for the integrity of your work as long as
you show your math.

No.

We are talking about a small antenna ~25% of full 1/4 wave length which
performs as well or outperforms its full length 1/4 wave version.

We are talking about a 1/2 wave antenna which is only 20-30% the length
of its full length 1/2 wave version which performs as well or even out
performs its' full 1/2 wave length ...

Show me an EZNEC model of what the Navy tested for Mr. Vincent--indeed,
show me where anyone before Mr. Vincent was able to demonstrate a
working model capable of the above characteristics?

Gentlemen,
Vincent did produce a shorter antenna than was known before
with a 50 ohm impedance feed which is a huge advantage for designers
that want to hide, encapsulate or what have you for a small antenna
in this wifi age and nobody can take that away from him even tho his
knoweledge of antennas is limited.
If he understood Gaussian law then he could have made the Gaussian
antenna
which requires an element in equilibrium which means a FULL
WAVELENGTH.
I know you dislike the meaning of the term equilibrium b ut here it
is
indispesable.
Even without the knoweledge of Gauss he came very close to Gauss
or the biggest discovery of the century
If one winds a half wave length in a clockwise direction starting
at the top going down and then repeating with another halfwave length
but winding it in a counterclockwise direction( preferably winding
both
wires at the same time) and then joining together the two wires at the
top
he would then have a copy of my Gaussian antenna.
Note that the errant current flow that Vincent has on the feed line
now has
a path to travel where it can radiate and still have a resistive match
at
the feed points. This by the way is bidirectional
Now one can again expand the Gaussian principle by making the antenna
height
less than the wound diameter to make a circular polarity radiating
antenna.
Also note that Gauss's work then leads to a maximum gain when the
antenna
is at right angles to the earth but knowing that a full summation of
all vectors
on the radiator is around 10 to 12 degrees from the radiator axis the
radiator
when tilted will maximise a particular polarity alone.
You can deride Vincents achievement as something useless but the
Gaussian antenna
is here,it is real and the mathematics regarding the extension of the
Gaussian
aproach gives an insight as to how radiation is really created which
has been
the goal of scientists for more than a hundred years.
And the experts on this newsgroup who were told of this first derided
it also.
Make a sample of a single wound antenna and then make a mirror immage
of same
and joining at the top. Then study it to determine if the windings of
an
inductor represents a portionof the resonant length...........
remember that augument, maybe you should revisit it! Yuri you can
provide
your normal account as to how antennas work in a contrary fashion.
And yes Roy you can repeat your phrase of "I don't understand it{"
As for others with computor programs you can alsomodel it for
yourselves
and then curse your computor.
