I have done quite a lot of testing in AO on dual band and single band quads
for 10 and 15 meters. I've done my optimizing on PII 350Mhz system that
moves very fast in AO. To date, I can not make a quad work as well in the
computer as a comparable boom length yagi. Now maybe it's just because you
can do better designs in YO. The dual band quad is a real trick on 10 and
15 meters. No matter what, the 15m quad screws up the 10 meter. You just
have to do your best and live with it. At my station, I had enough
property and resources that I didn't have to compromise with a dual band
quad. I still have the spreaders and the boom. Maybe some day I'll put it
up.
At any rate... I *** HIGHLY *** recommend you purchasing AO for your work.
It will save you a lot of time.
