Hi Randy

I've had a lot of luck in building the designs from this site.:

The designs are very simple to build and produces a good gain and pattern.
Above that there's a lot of yagis for both the 2m and the 70cm bands, there 
are some 50MHz, 70MHz (4m band in europe) designs and some designs for the 
low bands as well.
On the site is also some instructions on how to make the single polarized 
yagis into circular polarisation.

Hope you can use this for something :)

Martin, OZ1TMM
