Here are the specs on the
2 meter dish and here's the
model.
The finco p-5 and p-7 had a folded dipole driven three element yagi
(the p-7 had more directors I think) much like what john described
in his now mutilated post. Next I'll post a page on the p-5.
Then I'll try replacing the biquad on this model with the feed from a p-5.
I was actually hoping for more gain from this large of an antenna. I've seen
8bay whisker antennas that do almost this good with less wind area.
