    I've done some searches for this topic but came across dated information, figure I ask in case things have changed.

    I would like to split a signal to a HD-DVR and HD box. Would this be possible?

    If so, can someone recommend me a good splitter.

    Thank you for any help.

    This "can" be done only if you have a SWiM based coax. The Single Wire Multiswitch (SWiM) technology is specifically designed for this use.

    This thread: http://www.dbstalk.com/showthread.php?t=148509 will give you more information about SWiM.

    Cheers,
    Tom

    Thank you Tom for the reply.

    Is there a way to find out of I have a SWiM based coax?

    what kind(S) of RCVRs do you have?

    how many cables come from the dish
    is there a switch between the satellite dish and where the cables go into the house

    The quickest is to hit the dash button on your remote. The pop up will tell if you are SWiM connected.

    Or if you already know you have two coax cables to the DVR, you do not. SWiM only uses on coax to the receiver.

    Great! SWiM is Connected. Last question. Would a 2 way splitter from Radio Shack work?

    BTW - Vikings all the way! No I'm kidding. :D

    Regarding the splitter... Well the answer is unfortunately complex. The best splitter would be a http://www.solidsignal.com/pview.as...itter-(2-2150-MHz)&c=Satellite Splitters&sku= or 4way. The "green label" DIRECTV certified splitters are best for the long-term uses including networking over the SWiM line.

    On the other hand, a good, wideband splitter from Lowes or Homedepot will likely work too. Be sure it is rated up to 2.1GHz and as low as possible. SWiM uses a communication channel in the 2MHz range and many splitters stop at 5MHz.

    Cheers,
    Tom

    All,

    Hoping for some more information. I am also trying to split a one line into two receivers. My DTV was installed roughly 10 years ago so I do not think I have a SWM system as this is relatively new I believe.

    I went out and purchased a DTV approved 4 way splitter

    I've hooked everything up and I do receive signal and full channel availability to both receivers, HOWEVER...

    When I change the channel on one receiver, I get the Error 771 on the other receiver for a few seconds (10-15) before it reappears. Sometimes I have to change the channel to get it to come back.

    Any idea why this happens or anyway to fix it?

    As mentioned above, you can't split a non-swm signal. You would have to convert your setup to a swm type.

    Splitting a non-swim line to feed two receives could lead to both getting the channel they want, one getting the channel they need and the other not or neither being able to get the channel they need depending on where the channel(s) come from.

    The stack plan below helps explain why.

    [​IMG]

    Your receiver requests one of the 4 blocks by sending a voltage and possibly tone to the LNB. The combination indicates which one to send. If both receivers happen to be looking for a channel from the same block then both will actually be able to receive the channel they want. If they don't match then you'll end up with the combination of what the 2 are requesting with 17v and tone winning out over 13v and no tone resulting in one or possibly neither getting the channel they want. You need to run a separate cable from your dish or switch to the new receiver for it to work correctly. A switch will require 2 or 4 cables going into it to give you more outputs.

    Just before you get your splitter, could you share info on your whole system? If you already have 8 tuners on your system you cannot add another one. While it sounds like you don't, it would be really nice to know all the receivers you have in your system to know if you can add one more.

    Thanks,
    Bob

    OP started thread in 2010.

    The new problem concerns VTT23 who has a legacy system.

    As previously mentioned, you can only "split" with a SWM system.

    If you give details as to what and where you are trying to accomplish we will be able to give you a better answer.

    It is notable that this would likely involve upgrading all receivers ($$$) as well as the dish.

    Absent more comprehensive information about what equipment the OP has, the simple answer is that adding additional receivers without their own cabling direct to a multiswitch output is NOT possible.

    Any solution that allows continued use of "legacy" receivers will NOT come through DIRECTV itself.

    It is true that without knowing which and how many receivers VTT23 has (the OP's problem was solved two years ago), it is not possible to give a definitive answer; however, it is not necessarily the case that VTT23 has receivers that are not SWiM compatible. For several years, I had an HR21, an H20, and an H23. All are SwiM compatible, but because I had only 4 tuners, I did not have a SWiM. When I decided to add another receiver, I added a SWiM 8.

    Also, the SWiM 8 can support one legacy receiver in addition to the SWiM compatible receivers. Do not jump to conclusions concerning the cost of the solution before you understand the situation.

    You're making the horrible flaw of assuming that DIRECTV will install an SWM8. They will not. DIRECTV installs either SWM LNBs or SWM16s (if the number of tuners merits).

    It is possible to go around DIRECTV (as you did), so that's why I said it the way I did.

    They do when there is a need for it. The World Direct dish requires it to combine with a Slimline.

    There is always the option of buying the SWiM-8 from a third party and installing it yourself.
