My thought would be to use a vertical shaft of either wood (dowel rod) or metal, add two wooden brackets to the back of the radio that would allow the rod to pass through. Then add a suitable knob of your choice at the top. Add a similar size pulley below and attach to another pulley on the rotating antenna assembly, couple them together with dial cord or other material of your choice so that as the top knob is turned, the antenna rotates below. The wood brackets, dowel rod etc. could be made just long enough to reach at the back top part of the set without showing from the front and still allow for fairly close placement against a wall.
