I settled for 40 some odd turns of no 14 enamelled wire on the core...as
many turns as I could get on it....swr reads the same as before but the
signal to noise level is a lot better.
this will do until I homebrew a matching network...remotely controlled
variable cap and tapped inductor in parallel at feedpoint...to use the
antenna on 20 thru 10 meters. Unless someone else has a better idea.
In the past, I attached 10 and 15 meter radiators and radials on the same
antenna and it did fairly well on 10 and 15, but I think the gain and
radiation pattern will be a tad better if I go the matching network route.

Hi all...
I have converted an old cb antenna to an elevated 1/4 wave ground plane
cut for 20 meters. I know I can use a 5 watt 100,000 ohm resistor to shut
static discharges to ground. How many turns of no 14 enamel wire around a
T200 core would it take to do the same job?
thanks in advance, de Denton WB7TDG
