It's a true dipole, each leg is 1/4 wavelength and the overall length is 1/2 wavelength. This was from technician class!!! ;-) Your J-pole is a 1/2 wavelength monopole with a 1/4 wavelength matching stub. Conceptually different types of antennas, although the principles remain. Nothing wrong with any of them, experimentation IS amateur radio. I stopped at Home Depot on the way home tonight and picked up a few bits. It occurred to me that the 3/4-1/2 part I need does come in brass, so I got a couple of them and was going to see how it might solder (doubtful). It might work, though, to drive the brass screws through the reducing bushing, which still accomplishes my goal of making the mating surface the electrical contact, too.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
