Made an antenna guessing at the specs. Also did it do see how critical the angle of the dipoles were. Antenna pattern: http://web.archive.org/web/20130610164242/http://tradewhen.com/Log-Periodic-Pattern.pdf
The antenna did not work that well. So I went back and looked at the original picture and noticed the angle was quite different.
Oops, the original angle used was a bit wide. Hmm. S/B:
Now to test it. Tested average....
