Well, this looks like it was even easier to fix than I thought it would be.

I already had a Monster Cable Power strip down there, and it has a Cable/Sat Coax in and out.

I connected the tv cable to that, and bingo!! no more hum, at all.

I'm gonna experiment, I think I would rather put that in the attic ahead of my signal boosters, to be certain I do not degrade my signal any.

I'll let you know, I have not rechecked my signal, but I suspect it is fine now.
