Wait until you build a new house, have RG-6 installed with barrel connectors in each room, include an A/V distribution panel with room for satelitte switches etc, and even a conduit to a roof location (32' up), no trees or other structures blocking.
Installer arrives, show him the location for the dish, conduit for the cable, and the A/V panel for him to make all his hook-ups with room for the switches. What do you get at the end? Cable that is not in the conduit, and lets make sure we cut all the RG-6 in the attack, then forget which one goes where, forget your tone device so you can't tone it out.
Took 3 visits for E* Installers to get it working. I discovered the cut RG-6 in the attack after they left the first time and my OTA wasn't working on any TV's, and my XM was dead. I ended up paying a private party to rerun the cable, and use the A/V panel as it was designed. I was also told that the dishes should have been grouded per code, to the grounding stud, but they were not. I guess showing them everything, and giving them written intructions and a drawing from the A/V installer to make sure it was done correctly was to much to ask. I will gladly pay someone who knows what they are doing, rather than have the installers come back. It was $200 fix to get it all back working right after they left the 3rd time. Now I might have to get the two dish 500's replaced by a 1000. I guess E* wants their installers to do it, I would rather pay mine than have to go through that again.
