J pole question

Are you sure, Owen? I read it as the bottom part of the j-pole. I made a
j-pole once, the top was copper, and the support was thick walled PVC.
Obviously that wasn't an active part. The "u" shaped portion was all
above the support leg.
The antenna matched up well with moving the clips back and forth. Still
works okay. I don't look at them as any better or worse thatn a 1/4 wave
gp, or vertical dipole, both of which I had before. Did not measure for
feedline radiation, but I have people at home who let me know of such
problems.
