Back in the 7Øs, I had a steerable vertical array for 4ØM like that of which
you speak .. I read, re-read, studied, and decided the "way to go" was EACH
vertical have its own isolated set of radials. It worky worky swell. But,
this was the days before computer optimizing, and I have since read "proof",
as I recall, that an inclusive system works best. As the one I installed,
using coax and switches for phasing, worked so well, I never changed it, and
never had a chance to run A-B tests. All I know is that it sure performed,
each vertical independent of the others as to radials. I still had the
coaxial cable grounds offering a common connection, as my switches were not
double-pole. I am about ready to try that again, in my quite small downtown
lot. I have collected about enough aluminum for 3 32' sticks... HIHI

Hi All
I have 3 phased verticals for 40 and an inverted "L" for 160. At the base
of each of these, I have a pretty extensive radial system.
I run a wire from the radials at the base of each antenna to the radial
system on each of the other 3 antennas. What I was wondering was:
1. It helps
2. It hinders
3. Makes no difference.
