Default Optimized wideband antenna OWA

LOL...A dummy load does great in the SWR dept.. Doesn't mean
I want to use one as a radiator of my precious RF... :/
As far as Art's matching design proposal, I can't see the '98 article
in question, so as usual, my cat has mittens.

All I can find on the web is the following.

Some mention is made of QST here, but they did not seem to
actually publish the article:

Frank, I saw that those same people were featured speakers
at Dayton last week on the subject of OWA antenna progresions.
Also Cebik is selling computor disks on the subject.
Shame Jimmie and others didn't attend Dayton to point
out to the amateur world the shortcommings of such blather
and nonsense with respect to antennas. If they did that
they could have placed themselves in a position to be high
lighted in next months QST. I am sure all at Dayton would
have been all ears to their antenna expertese with respect to
various antennas. You also could have asked them why
their patent request was rejected !
If you look back at the archives around 1995 Jimmie may
find it interesting. By the way Frank a short time ago
I was blasted for something inmy past based on more
than a single reflector. I find it interesting the FM
antenna on the net that described the reason for three
reflecters by the author of AO *( Brian Beasely) so you
can easily determine who knows what he is talking
about on this group despite the impressions they try to create.

Frank,
I have been al over the place on the net with respect to articles
on OWA antennas and the only claims made are only per ideas.
Ideas can come from any where which also can include variations
of known patents so I see no problem./ The important point that
was missed that the closeness of the two elements is certainly
not intended as to provide a thick element to provide a wider
band impedance around which Cebik has written many articles.
True my method can provide wide gaps between the elements as
well as very narrow spacings which is where I focussed.
Basically my feeding method was the opposite arrangement where the
feed side of the matching system and where the element was split
to form a radiating loop nprior to the transfer point
.. The transfer point from this loop depended on the frequency of
use just the same as one would do when finding the ideal
impedance connecting point for any radiator.
However, every thing I have read is inferring that the band spread
of the OWA is created by two elements acting as oneto provide a
thicker element which ofcourse affects band width, but not to
the extent that it truly worth while.
Unfortunately Cebik bought this line of thinking
and extrapolated everything he wrote from that stand point which is a
pity.
If the seed had not been planted in the first place he would have
found things that have escaped him this time around and hopefully
one day he will realise the wrong turn that he made and share his
ideas in a more fruitfull way. This ofcourse does not prevent
others from picking up the ball and getting personal benefit from it
as I let the patent die when my heart faultering problems suggested
the
patent may not be the first thing to die! At this point I would
add that the Gaussian aproach is a much better one by placing all
data curves constant and in sync with each other which has been
major in creating a narrow band array as well as providing constant
gain
like a band pass filter curve and not a curve where different best f/
r
and gain peak frequencies forces compromises. Either way my reading
enforces my opinion of Cebik who is performing a valuable service
to ham radio since he writes things as he sees them as opposed to
slanting
to what he would like to believe, a very valuable attribute.
Best regards
Art
