Actually, I never saw that bicircle page. I just used circles based on
a post from Jeff Lieberman. I followed the Martysbug website as close
as possible except I used loops instead of squares. The wire length is
the same. Note the two wire feed used on that bicircle page is
considered to be the wrong way to do the feed. My feed is coaxial.
Instead of the pipe and coax shoving, I just hacked up a N to N
adapter.
