I was reading up on the above antenna which is a take off
of an antenna I patented ,( Constant Impedance
Matching System) and written up in QST March, 1998
I also described this system in earlier postings on this
newsgroup.-------------

What page? Can't seem to find the reference in March '98 QST.

Thought about past times so I looked up
comments on the OWA antenna on the net
and got the reference to QST from there.
By the way this newsgroup laughed at this
and ridiculed me when I explained it a
few years before the article was written,
the same way they ridiculed with the
Gaussian antenna. A lot of people were
pointed to this patent by the patent
office with respect to their claims.
Note Cebik did some follow up writing
on that antenna.I applied for another
patent along the same lines at the same
time but let it go when my health went
down hill!

Googled OWA and checked out he design of the antenna, Isnt this is pretty
much what you get when you let a program likeYagi Optimiser tweak the
antenna for max bandwidth vs SWR? Seems like back in the 70s I remember some
truck stop special CB antennas built like this that made great claims for
their SWR. No doubt the claim is correct but what is the tradeoff in gain,
cost, ruggedness.....

Jimmie, If the cb antenna is the same as what I disclosed in my patent
I should not have obtained the patent! I do know that a few patent
requests
were referred to my patent after I disclosed it on this newsgroup so
it seems odd that I and others were not referred to the CB antenna as
being the prior art. As far as gain trade off there is none. The
constant impedance allows for continuation of gain at band edges when
the gain striven for is to high for the bandwidth in question. But
then this is just a patent, and I have always found that people would
always say I already knew that or it has already been invented. Odd
how some people react to the new or change. It will be the same for
the Gaussian antenna
as already one has stated it has already been invented but does not
give particulars. On the impedance antenna I had numourous requests to
go to San Francisco with all expences paid just to discus the basics
and future
but health problems of the heart told me to forget about the whole
thing as well as the sarcastic comments from the resident experts of
this group
which continues to this day. I don't need money so I am glad the idea
is still alive ala Cebik who has written extensively about it. Really
you should refer your questions to him rather than entrap me into
another augument.
