Hi Phil

My antenna tuned perfectly until I added the 160 coil, then I had to
retune the whole thing and had lots of woes until I finally found that
sweet spot on each band where the SWR was down where it belonged.

It has been a long while and I don't remember, but I did have to make
a NEW feed coil in place of that enameled wire one that was more than
twice as many turns, same diameter, before anything came close to
tuning up right. I used the same gauge wire as the original, just
made it with twice as many turns, spacing was closer also. I did find
it's best to leave this new coil on a tube because it gets bumped
easily. What I did was cut the bottom out of a plastic cylinder about
14 inches in diameter and placed that around the antenna base. A
little round-up inside the container from time to time and a box of
salt kept the weeds out.
