Hey all, I have been losing digital channels and having poor signal quality. The cable guy came out and says I need different cable the kind I have is not very good for digital signals. what is the best kind of cable to run from the outside cable box on the side of the house through my basement to my HDTV Comcast box? I keep seeing RG6 but I wanted to make sure and do you recommend the quad shilded? Can I do the terminal ends myslef or do you recommend Comcast do the ends? thanks for you help.
