Hello all, couple of questions regarding my install. I had Comcast and currently have Rg6 cable entering the house in the attic, it all connects to a junction in the attic and then splits off to every room. I have already fished everything through the walls that I want. I have heard horror stories that the installer will not go into the attic without an extra charge, is this true? I personally think it would be easier then running cable along the outside of the house. Has anyone had experience with this. I am not asking them to fish any wire through walls, just mount the dish, enter the dish feed through the attic and use all existing lines that are there
