Did you model this antenna with the coax in the model?

I'm not saying the antenna didn't "work" and make contacts,
but it is extremely difficult to get a feedline off an
antenna like that without greatly affecting pattern. A
simple balun at the feedpoint generally won't cut it if you
want a true clean Bobtail pattern.
