I hate to admit it, but I think I've built them backwards over the

I think they suck?

Please pardon my ignorance. I understood that a J-Pole is a half wave
antenna connected to a quarter wave stub. The transmission line is
connected to a low impedance point (50 Ohms?) on the stub.

Yep, something like that.

In the literature, it is usually fed as an unbalanced antenna, but it is
not. Therefore, it should not matter which side has the center
conductor or shield - they are both wrong!

Well, if it really were a balanced feed, I guess(tm) there should be
no difference in the pattern, gain, VSWR, etc between the two
unbalanced methods of feeding the antenna. Yet the author of the
original article shows large differences in the antenna models. See
