I was able to run cables from the Sat dish to the receivers throught the attic. I then drilled a hole through the top plate in the walls that I needed to run cables through and cut a small hole approx. 1-1/2" x 2" in the wall where the cable needed to come out. This is easily covered with the cable receptical plate. I actually ran a phone line and extra cable run to each location. You can feed the cable down the wall through the hole you drilled and then find it with a coat hanger inside the wall from the hole cut at the bottom. This should work pretty well if you have access to the attic. It is much easier on interior walls as they most likely will not be insulated or have blocks part way down the wall between the studs. On the exterior walls you will have to deal with the insulation which is not too bad with the stiffness of the cable, but you may run into blocks between the studs in the wall that will not allow the cable to run all the way down. I ran into this and was able to measure how far down the block was down the wall by measuring the amount of cable I could feed down before it hit the block then I cut a small hole in the wall to drill a hole through the block to continue the cable run to the bottom of the wall. My walls were textured, so it was pretty easy to patch the wall with a little drywall compound. If you are running phone lines down the insulated walls as well, tape it to the coax cable and feed it through the hole in the attic with the coax cable. I suggest running more cables than you think you will need if you go to the trouble of taking on this task as it is not much more difficult to run two or three cables as it is to run one. Hope this helps.
