The RG-59 coaxial cable that was commonly used for regular television in many houses is a different grade than the RG-6 coaxial cable used to connect to DirecTV satellite dishes these days. I'm told that the RG-6 cable needs to be of a higher grade to carry power to the LNB of the dish itself, and that RG-59 will either not work or will melt through its insulation if you try.
