Tom, W8ji apparently is an expert with antennas having lectured
at Dayton and has authored many technical articles around antennas,
states that radiators must be straight for maximum efficiency,
apparently
It would assist us if you would cut and paste the quote from Tom' site.
As I said before, the only place I ever saw this was with reference to
Beverages- the statement is true and obvious to everyone except perhaps you
Art.
The onus *is upon you to prove that a Beverage in any other deployment
except straight would be better. I don't want to hear about your theories
that only you embrace- a simple EZNEC model will be sufficient.

Dale I am happy with the responses of the group. Seems like they are
united against the idea that radiators must be straight for maximum
efficiency. I never mentioned anything about Beverages, that was
somebody else. As far as Eznec is concerned I am not familiar with it
as I use a program equiped with an optimiser that tries to bring your
inputs in line with Maxwells equations. For instance, Eznec is only a
calculator devised to provide answers to that supplied with additions
to handle planar forms that are not in compliance. When you have an
optimiser and your input is not pre guided ,such as a planar input,
the optimiser will respond with a non planar design that includes
the
Coriolis force such that Maxwells equations are enforced , and that
requires equilibrium.
That also means the programs costs more but all antenna design
companies use them as they recognise the true value of adherence to
Maxwell's laws.
The above justifies my position on radiators unless you want to
declare "garbage in garbage out". I have a simple sample printed of a
computerized array that shows the above in the patent request that is
presently due for extinction. The military uses tipped radiators in
many places to gain coverage of the donut hole as I have shown, but
you will not see printed matter on the subject except from me. The WWW
changes a lot of things regarding secrecy. Remember, when Tesla died
he was working on a cheap energy system. The FBI raided his lab and
took every thing which even now has not seen the light of day!
I know. YOU now want me to provide a copy of the statement to you but
then,. you can choose to believe or not to believe and use free speech
to demand any thing. But I am not in your employ.
