I suppose soldering all the twists would fix it.


Probably would, but sounds damn tiresome.


Hardware cloth is already soldered.

Problem there Cecil is the windmill effect
on the rotor. Even tv antennas in the Midwest get a hammering
while power generastor windmills are sprouting all over the place
to harvest same. One of these huge windmills lost one of its blades a
short time ago

Hardware cloth, cheap, indestructible, easy, widely-available, etc. ...
don't under rate it!

Cecil
The antenna will be capable of use on ALL frequency so I will be able
to observe the ups and downs of the reflectors applicability when I
get it up.
7 inches of snow with two more clippers on the way has put a crimp in
my immediate plans
My thinking is that as the antenna is end fed the need for extra large
size reflecter goes out the windown
as the reflector may perform as a flux guide similar to a long
solenoid. This is new ground so I do not
want to nickel and dime it to death until I have more experience under
my belt. Present dish
education is heavily weighted to phase methods used in planar designs
or alternatively solely on VHF,
the later being slanted designs via pitch and other factors that do
not apply in my case. since my
design evolves around equilibrium . I would also point out that some
of Kraus's work is being thrashed
with respect to gain and may well extend to use of deductions instead
of observables which was heavily used
in empirical gains with respect to pitch angles. Bottom line at the
moment is that the antenna for top band
be light and small enough for me to handle on the towerand on the
ground without the need for me use my prop pitch rotor,
which by itself is a handfull or to call for additional help. If I
can't handle it alone then it defeats my original object with respect
to
small antennas without the normal compromises with respect to
electrical wavelength.
That ofcourse does not rule out diode action in the short run with
respect to poultry fence mesh as a reflector.

Hmmmmm, I don't seem to have that problem here in
East Texas. Y'all come on down.

We have heard rumors of that stuff here in California ... ;-)

It would seem to me, there are but two ways to couple to the ether,
either capacitively or inductively, if such is even possible (there
could be "something else", who knows?)

At a certain ratio of capacitance to inductance, in the design of an
antenna, that "magical/mystical value" of 477 ohms would be reached.

However, you emphasize the inductive coupling ... I see other antennas
emphasizing e and h fields and all sorts of stuff in between.

In all this mumbo-jumbo something may, indeed, exist ... to date, "I
just don't get it" ...

I don't emphasize inductive coupling, at least not with what I am
messing with now!
Inductive coupling infers planar antennas acting solely on
intercoupling of elements
while at the same time ignoring the edict of equilibrium that goes
with all laws of science
such that the effects of the "weak force" are ignored. With inter
coupling of elements
you only get approximations as the last element of any array
reradiates half of that
which it receives. Thus the array always needs another element
regardles of the number used
to obtain maximum radiation. In the case of array in equilibrium you
always reach finality
with respect to radiation. All very simple.
On the other hand this 477 ohms figure certainly is mystical to me,
what is the point you
are trying to make? Is it possible that the figure you are using is
bigger than you intended
by being larger than life itself

I will take a wild guess here and assume there is some connection to
the
aether which is eternally on your mind. Well John for equilibrium the
aether is contained
within an arbitrary border. That means that all forces add up to zero,
a simple concept of Newton
which also means that the contents are not nothing or a vacuum what
ever that is in celestial terms otherwise the border collapses.
You must also realize that what is within the border must be in a
state of spin as well as being in equilibrium
where spin requires the present of matter. So now you have a basis on
which one can define the Aether
which is something other than nothing or a vacuum. Knowing that
particles flow thu this that is surrounded
by an arbitrary border one could possibly state that for every
addition of a transient particle another particle must
leave and since particles atract or repel that which is in circulation
in spin form must in fact be cluster form of particles.
So John let your mind have a smidgeon of freedom accepting what is
known and put things together the best way you can
so that you have a datum line to build on or change as knoweledge
increases which allows the addition of logic by the removal
of past theoretical assemblies.
All the above is material that you can use in your determination if I
am of sane mind or not. But first you must set your mind free
accepting only that which you can personally derive from first
principles as something that can be built upon.

Brrrrr it is geting cold
