I'm not sure why the bidirectional coaxial cable Beveridge doesn't get
more discussion. It is described in ON4UN's book, and seemed to work
fine when I built one at a prior QTH, although it does take two
feedlines from what would logically be the closest end to the shack.
Given the price of RG6 and surplus RG58/59 it is easier and potentially
cheaper than open wire feedline. Three transformers and no relays.
(page 7-88 5th edition and earlier editions as well)
Is there some reason that a pair of open wires are significantly better?

Have you ever thought of using a 2-wire bi-directional Beverage? They are
not complex at all. It only takes one more wire, two more simple
transformers, and one more run of coax. A remote relay and four extra parts
even lets you use just one run of coax for both directions.
If you run a single wire Beverage in the opposite direction, then you have
to put up twice as many supports (unless you have trees). But with a
two-wire Beverage, you can use the same supports for both directions.

Use RG-6 line in the future and run another Beverage in the opposite
direction - NW.
