I'm running a second line into my Direct TV DVR receiver. Does it really matter what type of RG6 cable you run from Satellite outside and into your house? I just don't want to spend uneccesarily unless I have to. At the same time I don't want this to effect my picture quality as well. I need to know what type and where I need to buy my coaxial cable for running a line from the satellite outside and into my house. **I've noticed Ebay has coaxial RG6 the cheapest, but not sure if I can trust it. **Also, by the way I am not burying the cable, but just tucking it under my siding of my house from my Dish to the point of entry into the house (about 50 feet run before it enters the house).
