And for the second thing... I happen to have problems with
portraying a dummy load on a stick as the answer to all things
of a radiating nature.
I've seen his antenna, and I know how it was built.
It's a dummy load on a stick.
See for yourself. Don't just take my word for it.http://www.k8gu.com/webpost/unwin-antenna.jpg
Note that this antenna is for 160m use.
My MW receiving loop would likely out radiate that thing.
If I used my mobile antenna, it would get ugly.
All his antenna is, is a helical whip, with contra wound
windings to make it even more lossy than if it were wound
in a normal military manner.
The extra "coil" on top is basically useless, and only adds
a small bit more inductance to the antenna. Maybe enough
to scoot down the band a few kc's.. * :/
He says it needs no ground plane, but being it is a vertical,
it sure as heck does, if reducing ground loss is an issue.
Of course, if one is willing to ignore massive coil loss, it's
no large stretch to assume he has no problem ignoring
ground losses either.
What is hilarious to most, is that he uses bafflegab mumbo
jumbo to try to explain the workings of an antenna that is
not only prior art I'm sure, but also a very perverted version
at that. I compared his antenna to a MW loopstick used for
receive purposes only.
Look at the picture and tell me your analysis.
You can apply plain old known vertical antenna technology
and come up with a pretty accurate assessment of the
efficiency of his antenna.
Mumbo jumbo is not required for this task.
Fairy tales won't cut it either. Nor neutrinos, the weak
force, or the shoe size of Captain Kirk.
Maybe this will shed some light on my persistent
skepticism of his illustrious, but stinky design.
The antenna you are referring to is an antenna that does not transmit
but does receive. This being contrary to accepted amateur lore that
all antennas are reciprocal
It was given to a future doctorate from the University of Illinois a
University who as a whole actively disses any
ideas from outside the academic field So I gave him a antenna that he
expected to get.
Prior to this "gift" which I also related to this group in detail. I
found out that when you superimpose a helix over a helix in contra
wound form the
eddy current magnetic fields cancelled each other such that the
particles were not levitatedwhich is required for transmissionthe
latter which
From this I learned that a radiator can only be of a varied shape and
in equilibrium as long as there was no interference
to distributed loads. Removing this inter action from the radiator
allowed levitatiuon of the particles such that it CAN transmit as well
as recieve which is not determined by a levitation action. Try it for
your self and do not compare a resistance with out distributed
inductance and capacitance with multi windings of distributed
capacitance and inductance. I know that you never completed high
school but there is no reason to stop reading technical books
just because you were thrown out which is foolhardy not vengance. The
photo in question was displayed solely as a prop by those who wanted
to diss my theory which is exactly why I suspect that you are using it
now. and good enough reason for me to supply a antenna that I did.
areana. Now any antenna can apply an overlapping helix to any antenna
computor program including the very limited EZNEC program to determine
the results for themselves, it is not essential to have a optimizer so
there is no need to imitate a talking head in dissing what I am
sharing.
