I don`t know enough about Art`s antenna to deny it. I do know that
resonance depends on the reciprocal of the sq. rt. of the product of LC,
not its quotient.

Explosive results from an inductor were introduced by Kettering, I
believe, through interruption of battery current through an inductor to
generate a very high voltage spark to ignite the fuel air mixture within
the cylinder of an internal combustion engine for automobiles. Just as I
doubt the inclusion of a pendulum in Art`s antenna, I also doubt the
presence of an interruptor to discharge either the capacitance or
inductance in the resonant antenna.

If Art`s antenna is novel, useful, and not completely obvious from prior
knowlege, he may profit from it. I wish him all the best.

Hi Richard,

Heinrich Hertz might have something to discuss with you about his
experiments. Having said that (and undoubtedly upsetting an Arthurian
apple cart in the process) you are too kind to wish:

I think Sarnoff's QSO with HMS Titanic search ships may have eclipsed
the novel use and fulfilled the prior art part of this. [AKA all
things are known and/or have been done already.]

Anyone should be so honored! Heinrich Rudolph Hertz (1857-1894) was a
pioneer experimental investigator of electromagnetic (EM or radio)
waves, according to B. Whitfield Griffith in "Radio-Electronic
Transmission Fundamentals'. Hertz in 1887, eight years after the death
of J.C. Maxwell (the predictor of EM waves) proved Maxwell correct.
Hertz did so by generating the first man-made EM waves in his
laboratory.

I believe the Hertz antennas consisted of loops which did not depend on
presence of ground for operation. Hertz was able to create a severe
electrical disturbance in one loop and across a gap in the second loop a
spark would jump.

Hertzian radio waves are said to lie between 10 kHz and 30,000 GHz, and
probably include the range of Art`s antenna.

A Hertz antenna is said to have its resonant frequency determined by its
distributed capacitance which varies according to its physical length.

Yes it does. But it is only half of the story since it basically is
missing half of the circuit which the spark was looking for .
As you know a requirement is to keep the LC ratio, so basically he
had a tesla coil which is the opposite and was looking for the
capacitor
When you have both of these THEN you have the "circulating" current
which creats full radiation.This circulating current is ofcourse
in the form of pulses at twice per period where the spark is one of
them that is uncontrolled with respect to the frequency of the circuit
It is indicative of the time constant involved which is also a
requirement
of radiation
Close but no cigar.

I would argue with that based on the LC ratio for present day
radiators
but for Hertz it would be correct since his radiator did not have the
inductive storage of energy which was dissipated in a spark and not
returned to the capacitor.

Hi Arthur,

You really should read some history before re-writing it. Hertz'
antenna was a single turn of wire (as was the receiver's).

If you cannot figure out how Hertz' antenna resonance was achieved
(let me drop the shoe here, and say "in the conventional way"), then
you are more than 120 years behind in the game.

It really has all been done before. Books have been written about it,
several movies too, and perhaps a segment on the Discovery Channel.

For more than a year you have stated "it" has been done before and
none
of us know what "it" is. Thus your posts have no meaning to anybody
and is why they are seen as not worth while persueing. You are so
cryptic
that you fool yourself as well as wasting other peoples time.

Richard,
You just have to familierise yourself with what ia termed a TANK
circuit
When you do this all becomes clear.Since it is used in transmitters
it may well be included in ARRL publications. On the other hand
"Google"
the circuit. My guess is that it in the older books of Terman where if
you
see a chapter on spark transmitters it will appear in there.
Another good place to look would be Bailey's book with
reference to a flyback transformer. This is a very important area
to hone your antenna skills. Side note. I am not interested in profit.
Regards
Art

Conglomerate I worked for acquired Newport News Shipbuilding and Drydock
Company. They had their mission statement on a sign in front of their
headquarters. It read something like: "Our goal is to build fine ships,
for a profit if possible." That sign had to go immediately. Our company
was in business for profit which we expected as a consequence of
product, price, and service, even when building nuclear submarines for
the U.S. Navy.

Profit is good. Profit makes the world turn sanely.
