Will an antenna rotator like a Radio Shack or Channel Master work if

I know rotators are designed to handle a certain weight, but I can't
guess at what they'd do with a "negative" weight...

You've got a point about "negative" weight". Many rotators support
their load on the upper assy which, in turn, runs on a ball-bearing
loaded raceway. Probably a poor pratice to operate them upside down.

What you could look for is a rotator that permits the mast to run
clear through the whole works. These are often used in conjunction
with a separate load bearing supporting the weight of the mast below
the rotator. With a rotator such as this, you can mount the rotator
high in the rafters and run the mast _down_ from the _upright_ rotator.

It's a thought...
