Hi.
The one that I used was made out of copper tubing. There are a variety of
materials that you can use, and some of the parameters change a bit
depending upon the method of construction. I am not an expert on the
construction, but I have seen plans in the past for using 300 ohm ribbon
cable to make the J-pole. The copper tubing J-pole was nice because I
didn't have to worry about hanging it from anything--I just had to find a
way to secure it to the top of the TV mast that I had it mounted on, and it
was especially easy to turn it horizontal, since it was made of a rigid
material.
73, de Lou K2LKK
P.S. Mine was constructed by a fellow in the next town who used to make
them up and sell them at the Rochester hamfest.
