New install question. Please give your .02
I scheduled directv to install this week. I am an electrician and have wired my home with cat5 on gigabit and rg6 quad in every room. I have cable now and am switching. I do not want the satellite on my roof instead I would like it on my wood shed. I ran 2 coax and two cat6 to my shed underground in pvc pipe approx 75 feet away. The shed has a 60 amp electrical panel as well. The two coax meet in a utility room where the rest of my house connects, all are home runs. My question, If I am getting a hd dvr, hd box and 2 sd boxes will 2 coax from the satellite dish be enough to feed 4 or possibly 5 boxes. Also does the hd dvr need 2 coax or will 1 suffice. Thanks

With a new HD install, you will be getting a SWM (single wire multiswitch) system, which requires 1 cable from the dish to a switching point, then 1 cable for each HDDVR, DVR, HD, or std receiver. If you have high speed internet connection, a coax would also need to be ran from it's location for a DECA (DirecTV Ethernet to Coax adapter) to bring the internet to each receiver via the coax satellite feed.
The system does need to be grounded via the common (house) ground, NEC rules (as I'm sure you are aware of). From the dish, a #17 ground wire attached to the coax (actaully molded into the insulating pvc jacket of the coax) or a #10 solid copper if unattached ran to within 20 ft of the house ground (electric meter). Water pipes, gas lines, A/C power supplies are not, in most DirecTV offices, acceptable grounds. Must be (in order of preference) #6 bare copper to ground rod, meter pan corner/side clamp, or stainless steel strap on weatherhead. From there, 1 cable ran into your utility room to connect to your other cables.
Your plan, of course, relies on your shed being a sturdy mount for the dish, as well as getting proper line of sight. The installer will determine this, as well as be able to run the proper cabling if what you have needs to be replaced or added to.

thanks for the response. I guess I will be canceling my directv order. Why does each box need internet access and why does it have to be over coax? What if I didnt have internet?

you completely misunderstood redneck_tech's post. your two coax from the shed is enough for now. actually only one will be used. the receivers connects via coaxial cable. since you already have cable vision in the house that should be no problem. as far as the internet, that is NOT needed, but is a plus to get the internet connected to the system to enjoy the free features that DTV has to offer to connected systems. now only ONE connection is necessary, for the entire system. this requires one coax from the router location to anywhere in the DTV's coax tree.. but you DON'T need to have this.
