I really don't have a preference to running analog cables or using a RF modulator as long as the quality is equal to what I'm getting now, it sounds like you're saying either should work. The upstairs tv the signal is going to is a top of the line 20" Panasonic maybe 5 years old.

If I go the RF modulator route and use the CE Labs 1001ST it has selectable channels UHF 14-69; Cable 65-94, 100-125, do I just pick any channel to set it on and then set the tv to the same channel?

I suppose if I decide to run analog cables I won't actually know how well it will work until after I've already bought and ran the cables. I guess that could also apply to the RF modulator.
