Topband: Another non-traditional antenna working.

You sort of lost me a day or so Guy as the posts were getting way too long
and boring (-; that I deleted after the first page.
It appears that the FCP sort of took over the radial discussion somewhere
along the way when I was sleeping and the subject line changed..
How about we leave the FCP to those who live in a mobile home or a place
where the wife rules. I cant even fathom being stuck with a 10x70 yard!
And then concentrate on the average suburban ham with maybe a 100x100 or
200x200 or so back yard to play in as that seems to be more the norm on
here. At that prior QTH all I had was 100X200' to work with and the tower
was about 30' from the side street (which happened to be due East and yet I
had no problem in that direction after the mesh was installed), pure sand
and stone for a ground, and no place to tie off an L top wire. Instead of
endless discussions on copper wire radials of every length imaginable Im
trying to get the point across that an in close and dense layer of plastic
dipped fencing blows it all away and for little effort and money along with
good longevity. Any radials added to the ends is pure gravy. That is far
from a commercial quality installation as it wasnt uniform, length was about
.09 wave, and the density was only partial since the fencing was put down as
spokes. Lots of trees, brush, shed, and garage in the way. Not even close to
ideal by any stretch.
