Rotatable couplings?

One of the problems with beams is the cable winding around
the mast if you try to turn too far in one way or another.
These difficulties have long been solved in the world of radar,
so, has anyone conceived of an infinitely rotatable 50 ohm
coupling for our beam antennae?
Sounds like a $200 solution to a $0.75 problem, i.e. an extra foot or
two of coax to allow slack for turning.
I think the issue is that you have to manage the turning so you don't go
too far in either direction before reversing.
