I am hooking up my old atari, n64, and genesis, and the cables I have all use coax to the tv...as well as my cable of course, so that's 4 connections. When they are all wired together the picture quality gets pretty bad on everything so I'm looking for a switch that has 4-5 coax inputs. I know that I can get cables for the n64 and genesis with rca outputs, but I don't want to bother going that way. I searched quite a bit, and can't find anything decent with more that 3 ports...any ideas?
