Do a Google search on NW3Z. He has designed some monoband and dual band OWA
yagis. I am planning on putting up his 20M OWA which is 6 elements on a 48
foot boom. I used his element spacing and then optimized the yagi with YO
6.5 keeping the spacings fixed. It looks like it is going to be a really
good playing 20M antenna. BTW, he places the first director .06 wavelength
in front of the driven element.
