Hi Art,

Simply using EZNEC's freely available yagi design, I can come up with
a 11.4 dBi figure at 10 degrees. Can you say we have another antenna
with a single feed that has a TOA of 10 degrees with more gain that
this?

I don't think there would be a problem in beating that!
I would expect many could come up with one better than that at a feed
point height
of 1 wave length. Isn't the max gain theoretical obtainable just short of
16dbi ?
Allow for 0.5 db max losses seems like 15.5 dbi is obtainable.
( using perfect flat terrain ofcourse with a 60 foot boom 'big' yagi)
With all the experts that reside on this group plus a zillion of antenna
reference books
I expect many to come up with antennas better than that.
Isn';t all now known about antennas and placed in print? (Grin)
It just needs is a bit of research or an expert to share his knowledge
with civility.

Hi Art,

Thanx, I just needed you to confirm that you, in fact, did not have
such a design.

Do you really think that I wasn't wise to the games you play ?
You was gearing up for an augument so I gave you nothing you
could argue about. Check mate !

Now THAT sounds like playing games, when I ask for a technical
specification in a technical newsgroup.

Check mate !


as does that.

Hi Art,

It remains extremely difficult to separate these obscure postings
which defy distinction between your work and your fantasies, Art.
This recent introduction of TOA appears to have been fantasy.
