In logic there is the argument called Reductio Ad Absurdum. With the

man-made RF radiation, ALL such attempts have been preceded with a
resonant coil/capacitor combination. Think of the plate load of the
conventional RF transmitter in both amateur and professional
applications for the many decades that followed Hertz' work.

This small, resonant plate load, is quite specifically designed for RF
with low in resistive loss - and yet it is miserable as a propagator
of that same RF. The physical size compared to the wavelength size
dominates that efficiency with a fourth power law. Hertz' original
design was in the VHF where his "plate tank" (so to speak) was
physically large in relation to the wavelength he successfully
transmitted to a nearby physically large receiving tank.

A perfect example of an old man or woman not willing to accept change.
For the cost of a few dollars they would not have made such fools of
themselves over the years.
I have stated many times that adding a time varying current to a
Gaussian field of statics
represents Maxwells laws for radiation. The group many times over say
this is foolish and stupid. I know it is not stated or confirmed in
the books. When one accept that statement of mine the next deductions
become obvious.
A radiator can be any size, shape or elevation as long as it is in a
state of equilibrium and is in compliance with Maxwells equation for
radiation.
I have opreviously shown how static particles are part and parcel how
a Faraday shield works. I now have shown again how Maxwell and Gauss
also state that particles are part of radiation. In addition, the
particle is also part of a CRT mechanism as is the salvage sorting
system when sorting aluminum cans. I have also shown how the particle
achieves a straight line trajectory with spin unaffected by gravity
which is also essential to radio propagation.
Yet hams still hang on to the yagi and all its atributes as being the
cats whiskers.
Thus size has become everything and the volume it occupies instead of
distributed loads only as long as it is in equilibrium. The particle
responsible for radiation and light is very small and is the perfect
example of point radiation at its best.
All it takes is a few dollars and a few hours work to make such an
antenna, which allows you to stop making idiots of your selves, or a
modicum of physics. Instead, you are all so sure that you find no need
to get up from a couch.
As I have stated many times, all the group has done is the waving of
hands with no physics attached or any explanation why it is in total
conformance with antenna computer programs of the day in addition to
the points I have made. With groups such as this it is no small wonder
that radiation has not been fully understood for more than a century.

To extend this to Art's misinterpretation of Faraday Shields:

In the old days, breadboard design was exactly that - your rig was
built on (hammered to) a breadboard. It was open wiring with open
components. It radiated well with an antenna, and poorly without one.

However, as poorly as it radiated without an antenna, if you had a
separate receiver, you would hear yourself. This was sometimes useful
and gave us what is called "side tone."

The monitor was born.

Of course, with antennas connected, the receiver was bound to get more
than enough of that anyway and if the two were closely spaced,
feedback could drive all circuits into saturation. Not a good thing.
The Faraday shield for the transmitter was born.

It, as many can witness from simple observation, was composed of a
fine grid mesh of wire either tied to ground, or to a heavily AC/RF
filtered DC potential. As with all Faraday shields that came before
it (indeed since Faraday invented it), it completely encapsulated the
RF power source. The screen or mesh was simply a contrivance to allow
cool air to move in and hot air to move out. Modern implementations
use finned constructions and heat wicks - but this is topic drift.

With this added to the breadboard, other circuits also came to be
shielded, and generally so with the appearance of sheet metal chassis
with suitably wavelength small openings for access and heat transfer.
As the breadboard went into this RF impenetrable shell for both
receivers and transmitters (and with even more care for transceivers),
there arose a problem: What about the wires that go in and out?

Yes indeed. If those wires were not, in themselves, decoupled; then
they became radiators. The lesson to be learned was that those wires
had to be held at the same potential as the Faraday shield. This
could be accomplished by a simple connection, but with more than one
wire this leads to dead shorts between wires. Not a good thing.

The solution was to use AC/RF shorts (capacitors) to the shield from
the wire and the wire could only penetrate the shield through a very
small (in proportion to wavelength) opening. This was not always a
good thing.

A capacitor could be good, but it exhibits a roll-off of only 6dB per
octave, or 10dB per decade isolation. If your line going in and out
was a DC control line, and your principle frequency was 1MHz (talking
about the old days now); then you had 6 decades of separation between
1Hz and 1MHz - pretty good. If in the intervening years you pushed
the technology envelope and added voice modulation and that came
through the same wire; then your system shrunk to 3 decades of
separation between 10,000Hz and 1MHz. This might work, sometimes it
didn't.

As the years spun on, more wires penetrated that RF barrier, and they
needed to not only be isolated from the RF, but each other; and often
they contained very small signals that needed suitable signal to noise
ratio (noise being that soup of RF that was stewing inside the
shield).

Inline bypass filters were born.

The lines that penetrate a Faraday shield now appear to be more
multi-stage low pass filters with repeating sections of shunt
capacitors and series inductors. Their common (ground to the old
brass pounder) was the shield which was RF free (as it was decoupled
to a sanctioned earth ground). And lest we forget the principle
penetration of that old time Faraday shield:

The coaxial transmission line was born.

By all appearances, this line satisfies the convention of a small
opening through the Faraday shield. It's diameter is easily very
small in relation to the wavelength of the RF power it reaches into
the shield to tap. In a sense, it extends that hole in the shield to
some very remote area that is far from the operating position, and
then allows a wire(s) to emerge without regard for further shielding:

The antenna is born.

Funny thing, however, is that presumption of the shield of the coax
being inert, un-perturbing, quiescent, invisible, benign - for that
presumption is an illusion, a grand delusion. The line is very long
with respect to wavelength, it is in the field of excitation that has
been drawn out of the soup within the cage, and it is as much an
antenna as the wire that emerged from its end. Many familiar problems
rise from the ashes of this illusion. The exterior of the coaxial
cable appears to the field to be a very long, grounded radiator.
However, at any appreciable length (wavelength raises its familiar
visage with an ironic grin), this exterior surface ceases to be the
familiar DC grounding strap material, and becomes a full-fledge
radiator according to its physical length vs. wavelength relationship.
Not a very good thing, untill:

The transmission line choke is born.

To decouple the OUTSIDE of the coaxial line, the convention that has
been observed (to widespread validation) is to either wind some
sections of the line into Inductive chokes, or to add ferrites which
serve the same purpose. These chokes, to be fully useful to their
purpose, should be found at not only one point along the line, but at
several so as to suppress (wavelength based) couplings along the line,
by the line and by the field.

When the combination of all these methods are employed, then the
Faraday shield does what it has done for these several hundred years
while allowing the migration of RF power to a remote drive point, and
without allowing that RF power to re-intrude into the shield, nor
along the coaxial cable. Thus, the only evidence of RF from inside
the Faraday shield is that which arrives over-the-air from the remote
antenna.

Any other claim is a profanation of Faraday.

Further discussion about these wires allowing RF to slither through
what would ordinarily be impenetrable holes.

Those holes, whose circulating currents prohibit any coupling of
fields through them, as long as they are very small in relation to the
wavelength, can turn into free-flowing fountains of power with some
rather simple additions.

As mentioned, merely pass an insulated wire through the hole. If that
wire reaches into the interior where an RF field presents a very high
potential difference to the Faraday shield, then you have a capacitive
coupling to the exterior of the shield, through the hole, along that
wire. On the other hand, if you loop that interior wire back onto the
interior surface of the shield, AND that loop resides within the RF
field where it presents a very high magnetic component; then you have
an inductive coupling to the exterior of the shield, through the hole,
along that wire. Simply terminate the outside extension of that wire
to a suitable load, observing the conventions of matching, and remove
as much power as is practicable.

This is nothing more complex than the usual design conventions already
discussed under the coaxial transmission line considerations in the
post this derives from.

The point of this aside is to remark how easily (or difficulty) the
Faraday shield can be corrupted through indifference to first
principles.

So after a degree in literature you have taken to reading up on
science.
But you have only regurgutated what you have read in a physics book.
When I introduced this group to first principles every body on this
group were apaulled.
When I stated, and it was confirmed by Dr Davis, all started waving
the hands and insulted Davis and I." What" you said "you can mix up
statics with electromechanics"? "What foolishness is being stated
here." In your posting you never mentioned any thing of that!
You and nobody in the group has presented anything that refutes what I
have stated.
All this group have agreed on is that I am promoting a new fangled
science where all is already known. Now Avitar has never stated any
sort of physics that shows that he has studied in college other than
waving his hands. Ofcourse we have the ham who got kicked out of high
school so he couldn't graduate. Not his fault I might add, just some
mis understandings why he would not go to school, and it goes on. And
then we have Richard who says, why do we need new design antennas, we
have the yagi, what more can you want?
So the group is not going to rely on physics to disprove my comments
because they have found that deformation, insults and loud voices is
all they have to crush my claims, and it is just not working. Have
they made one? No. They know the true facts on radiation so they
continue to sit on the couch and wave their hands and yell

No you have not!
Every thing comes back to the initial finding that
by adding a time varying current to the arbitrary border of Gauss
which surrounds
a field of static particles provides the same conditions implied by
Maxwell's equations.
The group denies this fact possibly because the word equilibrium was
not of their understanding. Without understanding the connection
between Maxwell and Gauss
with respect to the addition of time makes to a static field ala a
dynamic field, it is impossible to procede with respect to radiation.
If one starts from the middle of the story where coupling of waves is
considered a basic physics understanding the debate leads no where.
Now I am not asking people to follow solely the path of mathematics
but of the concepts involved where the presence of particles is
present., To start from a small portion of the current flow and
thinking in terms of DC or the suggestion that time varying fields
cannot surround a static field is just ludicrous. The subject is
Classical Physics and one should keep on subject if one is to fully
understand radiation. Denial of select parts of classical physics
without supplying reason ans substituting insults instead is not going
to solve anything. And as you did not graduate from high school it is
perfectly understandable that you will find difficulties in parts of
the debate and yet you would like to contribute to the debate. But
insults will not get the job done.
Of course one can go back to the basics of mathematics way back in
Arabic times where
the mere presence of an equal sign denotes equilibrium or balance. The
equal sign is part of Maxwells equations so equilibrium is in effect.
This immediatly tells you that any radiator considered must be a
function of a full wavelength or a period with respect to a continuing
variable sign wave. Immediately one should note that a half wave has
no place in our calculations as the two areas under curve for a period
can never be the same because of overshoot phenomina, thus it is the
period that is repeatable and to be used. One can also deduce that a
radiator must be in equilibrium to be part of the same reasoning thus
resonance on its own is not part of the mathematics. There are plenty
of ways to see how current thinking on antennas is certainly not
inline with the equations of Maxwell, thus it is very important to
start from "first "principles and not just accept the books. And that
the importance of adding time to a static field enclosed by an
arbitrary boundary to ensure the correct metrics will be used at the
outset.

Give me a clue whether you are in junior high school or have a track

even given a clue that you have ever taken a physics course or for
that matter any engineering course in any of your postings.
It seems like you are awful young and not yet an adult to put some
scence or logic to any thing that you say! You talk of no "rational"
in my statements, but as yet have not presented
anything to back you up. I have read thru a lot of your postings but
as yet have not come across anything from which I can gauge some of
your knowledge and expertise with respect to antennas and radiation.
I have gathered that you have had some experience in installing
consumer dishes and I recall you stating that dishes can only be used
in the giga hertz range, without mention that it is the size of the
antenna determines whether a dish orreflecter is pertinant or not.
Very strange!
Because of lack of comment from others one can assume that they know
you better than I do and are content with a glance in the air with a
sigh and maybe I should follow like wise. I read your post again and
note that you want the math. If I gave you a starter with respect to
Gauss and Maxwell would you give me a hint with respect to your
present understandings with mathematics. Lets face it, you never
proved the mathematics wrong when it was presented to you by the good
doctor where every body also denied its correctness, so it is awfully
difficult to proceed when you deny the feasability of the initiating
statement. If it makes you feel good then continue with your insults
in leu of not knowing anything else to say.

I have, and on more than one occasion. But it goes through

They know the true facts on radiation so they
continue to sit on the couch and wave their hands and yell

I don't sit on a couch. I sit in an office style chair. And it
probably
should be replaced as it tends to molest my differential after a
while.
Needs more particuls between the frame and the top particul retaining
cover. Due to the weak force of my differential constantly being
supported by these particuls, they have achieved equilibrium and
no longer want to do any useful work.

No you have not!
Every thing comes back to the initial finding that
by adding a time varying current to the arbitrary border of Gauss
which surrounds
a field of static particles provides the same conditions implied by
Maxwell's equations.
The group denies this fact possibly because the word equilibrium was
not of their understanding. Without understanding the connection
between Maxwell and Gauss
with respect to the addition of time makes to a static field ala a
dynamic field, it is impossible to procede with respect to radiation.
If one starts from the middle of the story where coupling of waves is
considered a basic physics understanding the debate leads no where.
Now I am not asking people to follow solely the path of mathematics
but of the concepts involved where the presence of particles is
present., To start from a small portion of the current flow and
thinking in terms of DC or the suggestion that time varying fields
cannot surround a static field is just ludicrous. The subject is
Classical Physics and one should keep on subject if one is to fully
understand radiation. Denial of select parts of classical physics
without supplying reason ans substituting insults instead is not going
to solve anything. And as you did not graduate from high school it is
perfectly understandable that you will find difficulties in parts of
the debate and yet you would like to contribute to the debate. But
insults will not get the job done.
Of course one can go back to the basics of mathematics way back in
Arabic times where
the mere presence of an equal sign denotes equilibrium or balance. The
equal sign is part of Maxwells equations so equilibrium is in effect.
This immediatly tells you that any radiator considered must be a
function of a full wavelength or a period with respect to a continuing
variable sign wave. Immediately one should note that a half wave has
no place in our calculations as the two areas under curve for a period
can never be the same because of overshoot phenomina, thus it is the
period that is repeatable and to be used. One can also deduce that a
radiator must be in equilibrium to be part of the same reasoning thus
resonance on its own is not part of the mathematics. There are plenty
of ways to see how current thinking on antennas is certainly not
inline with the equations of Maxwell, thus it is very important to
start from "first "principles and not just accept the books. And that
the importance of adding time to a static field enclosed by an
arbitrary boundary to ensure the correct metrics will be used at the
outset.

Bla, bla, bla, bla.. We need to get you a new needle that doesn't skip
and play the same broken record over and over again. :/
You whine and moan about my education, which BTW, you have no
idea of knowing what I have learned in the 35 years since then, but
you
stun us with such proof of your all knowing knowledge by referring to
sine waves as "sign waves"..
Chortle..
Give me a break.. Your education in things RF is probably not much
greater than mine is being as you didn't take the relevant courses
in school. It might even be less being as I have a decent library
and I don't distrust everything I read without actually testing it
first.

And I actually build and test the antennas I talk about. On the air.
In front of real people. I've got nothing to hide. When was the last
time you actually compared one of your antennas to a known
benchmark?
At at a testing range. Or on the air.. In front of real people...

I'm afraid using mumbo jumbo pseudoscience theories are not going
to propel your obviously inefficient antenna designs to greatness.
I realize this must distress you greatly, but it's a situation that
can
be dealt with with the proper medications and therapy.
