I had a Hopper and Joey set up yesterday. They ran new cable on the outside of my house. This was OK, as we were able to enter the house with the air conditioner piping hole and everything was hidden well. But to get to my upstairs rooms, where I may want to add some joeys, I would have to have cables draped around my home. That isn't going to happen.
Currently I have some old RG6 cable that spiders from my attic to the various rooms in my upstairs. Would it be possible to run a line of new cable from the dish to my attic, and then connect to the old cable where it drops into the room below, so that there is just 5 or 6 feet of the old stuff? Or would it be better for me to learn to run my own line down inside the wall? From other locations in my house, it seems that the builders tacked the cables to the struts, so I don't think I can simply use the old lines to pull new ones through.
