I am getting ready to call Direct Tv in a few days to put in a order for 5 receivers (praying for H-24's) HD/Whole Home DVR (2 DVR's). Here is what I have done so far. House was built with RG-6 in walls of every room, I also ran all the cable to a central location in the garage with a hole pre-drilled in the wall for the Sat cable to come into the garage and meet up with existing cable. I ran a Cat 5E cable from my router through the basement to the garage with all the other cables. There is a electrical outlet in the garage to power DECA and for anything else that needs power. I have 2x2 piece of plywood that I plan to mount to the wall to organize all the cables after install. I should only need 1 RG-6 cable for every receiver, is this correct, anything I am missing?
