Hello...

Will an antenna rotator like a Radio Shack or Channel Master work if
hung upside-down from a roof beam, or should I try to come up with a
way to secure it to the attic floor?

I know the closer you get to the roof, the smaller the permissible turning
radius, so maybe you need to cut through the attic floor and attach the
rotator to the side of a joist. There might be 6" more room that way.
