Now you guys got me thinking. I Know it was DirecTV themselves that did the install. I am not sure of the quality of the cable used. It does run from the back of the house to the upper level where I live, a total of about 60-70 ft. And i am currently running SD, not HD(am looking to soon upgrade) and am very didapointed with picture, sometimes pixelated especially on cartoons.
I love technology! I just need to figure out how to use it. Keeping up with it's growing rate is hard enough!
