Mine is very simple. Made entirely from 1/2 inch copper tubing. Plans are readily available on the internet. Just type in copper J-pole plans into a search engine. The base of mine is made long (2 feet extra) and I've got it clamped to my chimmy with a metal strap and
muffler clamps. I've used LMR400 feedline on mine because the 100 ft run created 12db loss using rg59.
For a copper j-pole, you'll need 6 ft of tube, 2 solder caps, 1 tee, 1 90 elbow. You'll also need a pl-259 connector and a hunk of conductor wire. minus the feedline, about $25 at home depot.

through the foam and into the shield, shorting it out. I'll be cutting it off at the kink, rechecking it, then putting a new connector on when time allows.
