Hi Yuri,

snipirst of all, I have not done experiments to compare single wire
Beverages vs.
dual wire, with the other wire being laid underneath the Beverage.
I had the problem with statement "the wire below the Beverage is the wire
couples to the lossy media below it so well it becomes very
lossy" as far as I know wire maintains it's conductivity regardless where
it is
laid.

Yuri
Wire conductivity may not be pertinent in this case as "coupling" can reduce
the applied current
I would be extremely surprised if Tom inferred that wire conductivity
changed.

Perhaps more accurate statement would be that wire laying on the ground
becomes less significant in its contribution to the performance of the
above
Beverage.
But because the "ground" wire is connected typically at the termination
point
and at the feedpoint to the Beverage system, I am not sure that it can be
"ignored". Some claim this forms the "open wire" parallel system and has
significant effect on the Beverage performance. There is dispute as far
signal
arrival angles are concerned, some signals get subjected to wave tilt due
to
poor ground, some signals have their own tilt due to propagation and
terrain
effects.
To find out the reality, the exact systems should be compared in various
situations. Modeling might not provide fool proof answers due to some
programs
having hard time to model reality, that can be confused by varying ground
characteristics along the Beverage.
