Is there any performance advantage for RG6 over the old 59 coax cable, for either digital cable including HD channels or for using with a cable modem? I know that RG6 is shielded better, but other than that, does it have some kind of higher bandwith or data rate for digital data or video? I just bought and connected a new Sony 50A10 TV. The initial coax cable that is connected to the wall outlet is the old 59 cable. It runs to a Monster splitter I just bought. Then, one side goes to the cable modem, and the other side goes to the TV, which looks great.
