I have six 520 ft Beverages at six different angles occupying
the same 5 acres or so.  They can be fed from either end.
Various ones cross over other ones. I haven't noticed any
performance problems.  There is about a foot of vertical
spacing where they cross over.

There are also 2 or 3 Beverages at each feed point.  I currently
have a single ground rod with separate transformers, and switch
the 50 ohm side.  Previously, I switched the 450 ohm side and used
a common transformer.  Some of the terminations use radials
instead of a ground rod.

I haven't noticed any obvious degradation compared to previous
isolated individual beverages.  My experience indicates that it
is fairly difficult to screw up a beverage, except by not using
the right transformer or putting the wire up too high.  They
seem to involve a lot of land, a lot of wire, a lot of coax,
and a lot of walking, but not much rocket science.
