    I'm considering going back to DTV and getting their whole home network or whatever it's called. Anyway I'm trying to get an idea of what equipment is installed and how many RG6's are run from the dish? I'm trying to make sure everything is already wired and setup before the installation as my main tv wiring is custom do to a two story home. I've looked at other post but I'm a little confused on what is actually used.

    Thanks Mike

    How many DVRs and non DVRs do you want?

    As sigma posted, we need to know the number of receivers you will want in order to count the number of tuners in your system. Anything under 8 tuners they can do with a single RG6 from the dish. More than that requries a SWM16 and multiple lines running from the dish (I think 4).

    The way to calculate number of tuners is as follows:

    DVR & HDDVR Rcvrs = 2 tuners per device
    SD & HD Rcvrs = 1 tuner per device

    (EX. 2 HDDVR & 1 HD Rcvr = 5 tuners/ 3 HDDVR = 6 tuners, etc.)

    You see how what equipment is needed is all based on how many rcvrs you want.

    Ok, we'd be looking at two HD DVR's and one HD reciever more than likely. The only other option could be 3 HD DVR's. So that being said one RG6 would come in and go to ? I know it would have to be split to get the signal to the other recievers. If the equipment/splitter is small enough go behind my main TV center than the install would be easy.
    Thanks Mike

    Since you will a max of 6 tuners, you will most likely get a 3LNB with built in SWM. That will handle up to 8 tuners with one coax run from the sat dish.

    What you do want are the latest receivers, thats the HR24/H24 series. You can't request it from Directv but when the installer is on the way or they call earlier, ask them to bring the 24 series. Don't take older models.

    And with whole home be sure to order the Internet Connection Kit so you can have VOD and TVAPPs. Its an option to WHDVR service.

    JST,

    You would be looking at one coax coming from the dish into a 4 way splitter (technical term is multiswitch).

    One leg of this would go to a power inserter that sends DC current to the dish to power the lnb. (The PI can be located by itself, or can be placed behind one of your other receiver locations. The coax running into that room would then go to the PI first, then on to the receiver.) The other 3 legs would be used to connect to the 3 receivers you have in the house.

    If you don't mind all of the coax terminating behind your main tv then it's fine. Myself, and many others on here, have a space in a closet or basement that is out of the way that we have everything terminating at.

    Don't forget you will need a coax drop near your dsl/cable/satellite internet router if you are wanting to be able to run the internet apps/video on demand on your receivers. (This coax can be split to run both a receiver and the Internet DECA in the same location if needed.)

    Ok, can the single RG6 go to a dual splitter were one leg goes to the main tv and the other to the main splitter that the remainder of the house connects to? OR do all the cables need to connect at the original splitter ? That will determine what I need to do.

    Also there isn't a coax near my router. My house is wireless except the main computer.

    Thanks Mike

    Technically speaking you could do a 2 way splitter like you said, however I would not recommend it. When you start hanging splitters off of splitters you degrade the signal for the entire system. The best thing would have homeruns from each receiver location come back to a certain place where the coax from the dish resides.

    NO, you can do this without any issues "if you" keep in mind what you're doing.
    "Even if you exceed" the splitter & cabler loses, it "only effects" the end of this cable run and has NO AFFECT on the other runs off other splitter ports.
    There is a thread here: http://www.dbstalk.com/showthread.php?t=186663

    And perhaps more to the point is:

    These are close to the max lengths, so less than these should be NO PROBLEM!

    It woud be similar to the 2nd and 3rd diagram. The footage woud be less than 50 ft for any run. If they'll do this it would make things a snap.

    Thanks Mike

    "They should", but as you see above, there is some misunderstanding/lack of training, about how to deal with splitters.

    Understand most installers have had it beat into their heads that home runs to a switch is the only way and now some haven't completely made the switch to splitters. This tends to have them use an 8-way in place of the old switch figuring this is a "good thing". :nono:
