Just my two cents, I'd run a minimum of two lines to each outlet (one for sat one for OTA or to use a scondary DVR line). I'd rung a minimum of six lines (seven or even eight might be better) from the dish mounting point to the junction under the stairs (four for the AT9 dish, one for the OTA and one or even two for future use or as a spare incase one line gets damaged along the route). Also add a ground wire to run from the dish to the junction and from the meter base to the junction so you will have a bonded ground for your system. Just remember, while running coax you might not need now may seem like an unneeded expense, if you wind up having to run it later via wallfishes (at anywhere between $30-$100 a wire) will cost you more. And make sure you rung a phone line to each outlet as well. The more stuff you can put in the walls the less holes the installer will have to drill in you nice new home. You know what kind of builder you have working for you, but you never know what kind of installer is going to show up, the less drilling he has to do the better off you will be.
