Bill,
For a bi-directional Beverage, the termination resistor does not go at the
far end, regardless of whether you feed it with one coax or two. A
reflection transformer goes at the far end, and two other transformers go
at the feed end.
They can be put one above the other, but I would not do it at a 12" spacing
as it could cause unbalance and a degraded F/B ratio. We have an
explanation about that at
