The antenna rotator was a Magnavox unit purchased from Amazon for about 60 bucks. It looks very similar to the more expensive Radio Shack unit and looks identical to the AntennaCraft TDP2 rotator.

I painted it black to reduce its visibility from the road. In retrospect, flat black would have worked better. Reflections from the satin finish are obvious on sunny days, but it's not too bad as-is.
