even if it was broadband to a reciever or broadbndmodem of a sort, it would still be coax coming out of that to your set or reciever, but that brings a question to my mind. can cat 5 handle digital data better than coax? if lnbs changed to have a cat 5 port and tv's alike, would it be a better picture?
Lightening seems to LOVE phone wire so I would not be surprised if it was the same with CAT 5.
