Hi all,
Good to see the reflectors back up.
One of my TH7s developed some problems recently, and I wonder
if anyone has ideas where to look for trouble.
I purchased this TH7 used about 2 years ago. I was told it was just
a few years old and appeared to be in excellent condition. I am
using a Palomar BA-2000 balun with it.
Recently, the antenna has developed a higher than usual SWR on
15 and 20 meters, running between 2:1 and 2.5:1. It is just about
flat across both bands. 10m seems to be fine. Has anyone else
had similar problems? Is the most likely source the traps on one of
the driven elements? Comments appreciated.
73,
Barry
