One way to do it with a single piece of stiff coax is to place a standoff about a foot long above and below the rotor. Then form the coax into a spiral of several turns between the standoffs. Rotation will just tighten or loosen the spiral and not stress the coax at all. The standoffs also take the weight of the coax.
