That's basically what I said. All that is needed for a vertical "dipole" is a quarter wavelength of wire and a common mode choke a quarter wavelength back down the shield. The outside of the coax shield will happily radiate, regardless of the insulation. But everyone seems to want to do more work than is necessary. :D

Michael,
You could put a clamp-on choke 1/4-wave down the coax, coil the coax up at that point as a choke, or just slide a 1/4-wave piece of copper tubing over the coax and solder the braid to it.

Thanks to all responding. I found the tool, a new GC brand on Ebay in Pennsylvania, not far away. A better understanding of what I was looking for helped much. As a side note, I¡¯ve decided to use RG-11 for this seamless feed-system/antenna (vertical polarized), after calculating the power handling capability of the Belden 8279 ¡ª pret-ty small.
Take care.
