Gary,
Just make sure that all of your receiver cables go out to the area, where you will have the dp34 placed.
I do a lot of high end custom installs. The easiest way to do this is to drill a one inch hole in the eave's ceiling right near the wall. At first, drill a 1/8" hole and feel for space with a coat hanger wire, so that you do not hit a rafter. A 1/8" hole is easy to repair, if you hit a rafter. Go to Home Depot and purchase a three piece Greenlee "fishing rod" set in the electrical department for about 30. Using the spear tip, push the rod into the hole, tilting it toward the deck of the roof into the attic. Go into the attic and strip the coax down to the center wire. Find the tip of the "fishing rod" and thread the coax center wire into the hole. Twist the wire into a loop. You can tape any other coax around the outer jacket of the first, while making a smooth transition with the tape. Go outside and pull all the cables out with the "fishing rod."
Don't count on the installer doing this for you. They will most likely cut a large hole in the ceiling of the eave.
