We are getting a new Direct system installed in the next few weeks. We are looking at 2 HD-DVR's and 2 HD receivers, Choice Ultimate package, and the Whole Home DVR service. After reading up on a few different threads, I am confused with the whole DECA thing. Is one DECA needed for the whole home on the main receiver, or does each receiver in the house need a deca installed? Also reading that the new SWiM system requires a higher voltage to operate and has to have a power inserter, where is the best place to have the PI installed? Also our home has recently had the RG6 wiring in the attic upgraded to carry HD signals and cable internet to the modem. When Direct comes to install the dish, with they use the existing wiring in the attic or run new lines on the exterior of the house. I know a bunch of y'all are going to laugh at these simple questions, but bare with us Direct noobs!
