Hi, Carl,

I repeat, a folded counterpoise is NO substitute for a dense and
uniform system, which is what you had in the end.

My question for you is if you had a 70 x 10 foot strip of that rocky
stuff to construct a counterpoise, and that was all the space you had,
period, and your neighbors hated your guts, what could you have done
in that 70 x10 foot space?   The FCP as a device is decidely NOT in
competition with any sturdy conceptual extension of the commercial
grade dense and uniform radial field.  To anyone, if you can do dense
and uniform, then do dense and uniform. You will love it. You will
work lots of good stuff like Carl.  You need not be concerned with any
of this thread.

But if you can't do dense and uniform, then get decoupled from the
dirt.  Absent dense and uniform, dirt (especially the rocky, sandy and
urban mishmash kind) is your enemy.

N3ND is in a small lot, it can ONLY go THERE, PERIOD, kind of
situation.  The only reason we haven't just totally disinherited him
and stripped him of his Master's degree in plotting and conniving for
backing himself into that kind of a corner (literally), is that it's a
wife's dream house kind of thing.  Very pretty, very lovely, gorgeous.

AND the FUN of it is, we've got him on 160 IN SPITE of that, without a
hint of going ugly  :>)

73, Guy.
