BB Hello...

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

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

BB The antenna I'm looking to rotate is a Channel Master 8-bay bowtie.

I think it might work because rotators are rated for a large wind load
and hanging upside down doesn't even seem to come close to that.
However, I'd call the mfr first to ask for their recommendation
before doing it. I doubt any gears in the rotator depend on gravity to
stay in place. OTOH do you think fix mounting the rotator shaft and
having the antenna hanging off the mast fixture instead might work?

A*s*i*m*o*v
