That 2nd picture you have helps a bunch. My bi-quad that doesnt work is exactly the same as your first one, seems that tonight I will have myself another project
I'll let you know how it turns out. Looks like that bazooka cantenna you made turned out pretty nice, aluminum foil sure looks better than my hacked together metal screen (i didnt have any aluminum foil at the time) Im sure if you made the conical section even larger, it would have an even higher gain. One thing I found out is that having a strong signal in netstumbler doesnt always mean a good connection.
So far on the satelite antenna, its been connected for a few days straight now, with only a few 10 - 20 second dropouts a day (maybe once every couple hours) but other than that, it seem to be a very fast link. I'll try and post some more pictures when I get my biquad completed.
