    I've viewed all the KA/KU installation videos and it's not clear to me how many RG6 feeds you need from the dish to the home for a typical single receiver system (ex: HR22) HD/DVR installation?

    I currently have a single LNB std. Direct TV self installation consisting of 100' of underground RG6. Do I need a second underground feed? I assume the second Sat In on the receiver is for DVR. Will I simply sacrifice DVR funtionality if I stick with one feed from dish to home?

    Unless you install an SWM, which only needs 1 cable coming into your home, you will need 2 cables connected to your HR22 to enable the ability to tune to two different channels.

    Your HR22 will work with your current set up, but it will only be able to show and/or record one channel at a time.

    It will work, but he will also miss out on a lot of the HD channels since it is an old single lnb dish. To get the most out of your HR22 you will need a newer dish to get all of the programming for your HR22

    I suggest that you have all four lines run from the dish for future expansion.
    Unless, of course you get an SWM install.

    You need a slimline dish. There are 2 different types of LNB technology you can put on that dish. One is SWM (Single Wire Multiswitch), in which case your existing single coax should be sufficient. The other, legacy technology, will require four coax, and those should be solid copper center conductor (which you most likely do not have on your single run).

    Even with the legacy LNB technology, you would still have DVR capability on your DVR with only one input. The only thing you would lose is the ability to watch one channel live while recording a second, or to record two shows at once.
