I had the idea that it will behave like a long terminated dipole, giving the
pattern of a not terminated beverage of half the physical length.
My problem will be that both ends of that beverage I am thinking of would be
not on my own property.
Therefore Coax runs are not possible, but overhead wires are.

that makes a dipole not a beverage. A Beverage MUST be fed at the end. It
is a traveling wave antenna, not a conventional coupling antenna like a
dipole
If you must, build the feedpoint at the end and run the coax cable back
along the ground under the beverage- bury it a few inches if you can and
add a ground post where you make the turn to go to the shack - all an
attempt to decouple the shield of the coax from being part of the antenna
