that i built one myself, well me and my good freinds
here it is
using a single bi-quad we got gains of ~25dbi
with a double-eight we got gains of ~29dbi
it seems too directional for its own good
its very hard to keep a lock on anything with a person holding it
so we had to mount it and try....from the roof of a 12 story building!
im taking the pictures
