I sliced the rudimentary mounting pin off the back of the antenna. I cut four "V" shaped support pieces from .015" sheet. Two were cemented to the back of the dish with a length of plastic rod between them for the pivot. Then the remaining supports were cemented to the outside of the pivot and to a disk cut to the same size as the mount on the top of the Falcon. I chucked a piece of sprue in my moto-tool and turned a truncated cone to fill the empty space inside the dish. A hole drilled in the center of the cone was filled with a small sphere made by mushrooming stretched sprue.
