My parents are switching to D* from uverse. Everything they have now is hooked up via Cat5e cable. I know that won't be able to be used to carry the sst signal. There is a Rg-6 jack in each room though. My question is, is that enough for each room. Because after looking at the receivers I think they will be getting a HR24 and 3 H24. I have also read about the SWM technology. Kinda clueless here as I'm a E* guy. Thank you for shedding some light as I'm sure this has been asked before!
