Clay, I have built many antennas using coaxial cable. The VSWR is less than 1.05 to 1.00. I'm using the same type of antenna for my comm radio.
I have written up a blurb on how to make one, install it, and tune it. If you will contact me directly with your e-mail address, I'll send it to you. Jim Vance va...@claflinwildcats.com
