    I presently have two DVR's (with two dish inputs each) but they don't
    run HD, just standard definition. I need to have my house re-roofed and
    my old non-HD oval dishes will be disconnected until the work is done.
    My son has an HD dish system on site with one unused outlet. Can I
    somehow use a splitter on that feed to run my two house receivers? What
    kind of splitter do I need? Thanks for any help!

    You misunderstood. I don't have nor want Dish Network. Both my and my
    son's systems are DirecTV but his is HD and mine is not. My question is
    if I can connect my receivers to his dish with some kind of splitter,
    and if so, what kind will work. I can't make any sense of the online
    info so I don't know what to buy. This will be a temporary hookup while
    my rooftop hardware is removed for a time during construction.

    I don't want HD. My question concerns what type of splitter will work to
    allow me to use my sons HD DTV dish for my own non-HD receivers. I just
    want to be able to run my non-HD DVRs from my sons HD system dish
    temporarily while my old DTV hardware is off the roof.

  4. Do you plan on both being used at the same time? This will not work,
    if so. If you are going to use an LNB that is not in use, this
    might work. Depends on your receiver.

    We've got DirecTV here, and have two receivers - one is HardDrive with
    memory and the other is a standard receiver.

    You HAVE a standard, non-memory/recording receiver, but NOT the antennas,
    so you want to share antennas with your son who has the HardDrive
    Receiver, Right?

    Our house is wired with coax going everywhere. In one room is the
    HardDrive receiver that connects to the antennas (we have two antennas,
    one is regular and the other is international) through a powered unit
    inside the Access Control Box [where telephone, coax, and burglar alarms
    wiring all come together]

    To use BOTH receivers I merely plug in to any coax outlet with the
    standard receiver. No splitter involved. Unused outlet coax's are NOT
    terminated. Doesn't seem right somehow, so need to check the Access
    Control Box again. Might have a splitter inside the Box.

    I know that from the Access Control Box out to the antennas REQUIRES a DC
    path to run the LNA's mounted on the antennas, and there are two separate
    cables for that. However, I'll have to check regarding splitters FROM that
    controller performing distribution out to all the coax outlets in the
    house. There's probably about six at least, maybe eight. I vaguely
    remember seeing a 1 to 6 splitter going from the powered unit inside the
    Access Control Box out to each coax outlet. I purposely don't power all
    the coax outlets in our home, so [from memory] some of the splitter
    outlets are terminated with 50 ohm caps.

    So, my conclusion, without going to the Box and opening it to find out, is
    that *if* you go to your son's control box and tap into an unused coax
    outlet, you'll be up and running with YOUR receiver. If there is no
    'extra' port, try inserting a DC coupled 1-2 splitter to replace one line.
    Again from memory, the installing technician said that may work for us in
    order to expand our coax outlets.

    And one caveat Be VERY careful if your houses are any distance apart, they
    will have different AC grounding points. You could end up with some
    distructive ground loops that can weld your cables. I say can, because if
    you're next door, probably not that bad. However, during any lightning
    storm all bets are off as to what may happen. If it were me, I'd put an AC
    current meter between your two house grounds and measure the current,
    hopefully VERY low. And, *IF* a storm appears physically disconnect your
    cable until storm passes, else you could lose PC's, appliances, even
    telephones inside house(s).
