Hello, I have a vertical antenna that is tuned via taps on a coil at
the base. As I was moving the tap the other day I had the idea...why
not replace the tapped coil with a roller inductor? This would
certainly make tuning easier and as long as the roller is protected
from the elements should work as good as a fixed coil. Is there any
reason why this wouldnt' work? Has anybody else modified or built an
antenna using such a system? (For the record, the antenna is a Hy-Gain
AV18VS. I used to use it only on the low bands and as such rarely had
to move the tap, but now that I have an amp and this is the only
antenna I have that can handle power, I've been using it more often and
on more bands).
