one more item for you to consider, every building regardless of material used has built up corners, like 3 2x4s or whatever, if you have a lise of sight from any corner , go to lowes and buy 6 hex head self tapping bolts with rubber grommets buy the appropiate bit. when the tech shows up tell him you will sign off on his work order that he is not being held responsible for the mounting method. dont worry it WILL hold up. then go to radio shack and get a 50 foot piece of rg6/2250 coax and run it from the dish location to the splitter. then call the install co for an install date and tell the tech to get to work, the tivo line is his problem, tell him to do it the way that will be free. good luck
