Scaling shouldnt be an issue so start by looking at 1296MHz antennas.
You can always computer model them as well. Have a look at Mr Cebiks'
website. (http://www.cebik.com) I'd actually recommend you look at a
corner reflector. Nowhere as critical as a yagi and pretty easy to
build. Maybe even a 3D corner?

I've been wanting to try a Sterba curtain (on 900mHz) over a planar
reflector. That wouldnt be real critical either.

Exactly what i wanted to know, i may hold off on this one and search
for a different type high gain uhf antenna. Only problem is all
the design programs i have found on the web for yagi or log perodic
antennas are for 6-8 elements maximum, @ 900mhz i would like to have
as many elements as a boom would support. So my next question would be
where to look for a multi element beam using atleast a minimum of
twelve elements?

I thought it sounded familiar.

I have not kept in touch the last decade but Bill was a mentor to me.
He did a lot of antenna experimenting, especially on 432 mhz. He is
listed in QRZ.Com, you might send him a snail mail.

As I recall, the article was written during the building of the
antenna. Testing after the article was published did not support the
calculations. Unfortunately you cannot "un publish" a hard copy!

Most of us were still using slide rules & calculators to crunch number
then!

No Jerry its August 1977 - 73 magizine, im looking at it now & they
try and compare all other antennas to it and noe even come close. The
article was writen by Bill Parker W8dmr, anyway i think i will stay
with a yagi type or try ands build a 8 bay biquad like the Channel
Master uhf tv antenna.
