    If you have a SWM8 yes, assuming all the lines go to the location of your SWM8. If you have a Slimline with a SWM LNB, you will also need a two way splitter to feed the two four way splitters plus a termination for the eighth (unused) port.

    3 DVRs & 1 HD sounds like "just" one 4-way would be needed.

    Right. I guess I had another senior moment (they seem to be coming more often) :D

    Just looking to re-confirm ... (others have in other thread).

    For a dual SWM-8 setup, the preferred method is to use single power-passing splitters from the dish to the SWM-8's?

    One SWM-8 on the power-passing side and one SWM-8 on the non-power passing side.

    I'm using PV23-402's between the dish and the SWM-8's.

    Appreciate any comment due to some recent issues.

    I would have said to use dual-port power passing, but from other discussion, it appears that the SWM8 and constantly supplies the necessary 18v/13v/22Khz combinations to the LNB's. In this case, only one port needs to pass power so this should work.

    Sometime back, Earl & I went over splitters with powered multi-switches & non-powered. He knew of problems using splitters with both legs power passing, so there does seem to be "something" that happens using both legs power passing. With both multi-switches non-powered, you must use splitters that will pass from either leg.
    Your link looks like it is close to this one: http://www.a1components.com/itemdisplayn.aspx?item=4349

    BUT: the Skywalker is "diode steered", which means either leg can be power passing.
    With two powered switches, I would think Skywalkers would be a better choice because: with a single leg splitter, only one drives the dish. Should this one lose power, the dish loses power, but with a diode steered, the "other" switch would then power the dish.

    Given that you already have your splitters, I would used them, if they're not damaged.

    Hmm. That's interesting. I am using the Skywalker splitters currently.

    Well, if I ever get rid of my legacy equipment entirely I can replace the WB68 in my own setup and see how it goes with two SWM8 modules. :)

    I have the following setup.

    HD23-600 - - - - - 5LNB
    HR21-100 - - - - - 5LNB
    SAT-A1 - - - - - -5LNB
    SAT-B1 - - - - - -5LNB

    The 5LNB was installed in July.

    I want to replace the legacy SAT-A1 and B1 with another HR21 or HR 22 and another H23.

    Can I just replace the old receivers with the new or do I need a SWM solution?

    Thanks,

    A DVR has two tuners so you'd need to connect two coax for each. If you can't do that, then the SWM is the means to have both tuners function with only one coax connected.
    So:
    H23-600 [1]
    HR21-100 [2]
    HR21/22 [2]
    H23 [1]
    equals 6 tuners/SWM channels

    So based on what you describe, is it correct you've only got one tuner working on your current HR21? If so, it seems to me the installer more or less ripped you off when they put in the 5 LNB dish. He should have connected a multiswitch and run two lines to your DVR. That would have allowed you flexibility to add more DVRs and only run additional lines.

    Now, as VOS points out, an SWM would be your best upgrade option since you don't have a switch anyway.

    We don't know if there is a WB68 or not.
    "It might" only take another cable coming from a WB68 to the new DVR.

    There is not a WB68.

    I understand I do not have the extra tuner option on the present DVR. The cabling to the two HD receivers is a "home run" from the dish location to the wall outlet in the rooms. This was done about 13 years ago when I wired the house. I did not have the foresight to run home runs from the dish location to the other possible locations. The other two connections are to receivers that have a connection in a 8 way splitter in the basement. This splitter was installed to send OTA signal to other outlets in the house. I would have never thought of having more than 2 receivers when the house was wired.

    If I go forward with a SWM LNB, then I have to do major work to get to the "home runs" and make connections.

    I guess my original question concerned just not worrying about the dual tuner issue, but to get HD satellite signal to the two new receivers.

    Thanks for the help.

    It sounds like a SWMLNB is just what you want then. You'll use one coax from the dish, change your splitter to a SAT splitter and be able to have your "home runs" off it to each location [or even split down stream if needed].
    With a single wire to each location, all of your tuners will be active [up to eight total].
    What type of coax did you use?

    RG-6

    I had not thought of that option. OK, where do I get the SWMLNB and does the dish have to be adjusted? Also, where do I get the SAT splitter? Which one?

    I like [and have had good luck with] Skywalker: http://www.a1components.com/itemdisplayn.aspx?item=4349
    They come in both 2-way & 4-way.

    If you have a Slimline dish, then you can "just swap" the LNB [+ Power inserter] and if you're careful no realignment is needed.

    Here seems to be a good place for them: http://www.solidsignal.com/satellite/directv_slimline_swm_dishes.asp

    I've been getting DirecTV 'stuff' from SoldSignal for years, and they have good service and reasonable prices on everything from cable to WB616 MS's to SWM's. Recently purchased my SWM-8 with PI and DirecTV 4-way splitter (yes, I now know it doesn't matter... but that logo looks good! :) ).

    They have the Skywalker splitters, also, but if you need a bunch, it's cheaper to get them from A1 Components. I just got the 10-pack of the 5-2300 MHz Skywalkers, and the price each comes to $2 (not counting shipping, which is variable, of course). (You may need that many splitters if you are splitting the inputs to a multiswitch, and diplexing/de-diplexing OTA.)

    For example, here's their 10 pack:

    Hi veryoldschool (and everybody):

    Thanks for your link. I was checking out your SolidSignal post for the SWM LNB's, I have been waiting for SS to start carrying the SWM LNB. I am about to purchase a SWM LNB setup. (I have the central media/cable box in the garage and want to enable the dual tuners on the HR20 downstairs and still feed an H20 updstairs all via the single cable line, so I think the SWM LNB will be my best bet.)

    Anyway, my question being. Should I buy the setup parts (SWM LNB + PI + Splitter) piece meal from Solid Signal or buy one of these "package deals" on Ebay? It seems cheaper buying from Ebay...but buying Solid Signal adds a bit of confidence.

    Also, I am now seeing SWM LNB 5 and SWM LNB 8 on ebay....aren't they the same thing, just mislabled? Shoudl I be using the SWS splitters that most feature?

    Thanks!

    [simply put] eBay is a crapshoot. "More than not" these items seem to have "fallen off the back of a truck" [aka an installer had "leftovers"].
    I've been using the Skywalker splitters, for over a year, with both the SWM8 & [now] SWMLine and had zero problems.
    I'm sure the "SWS" splitters work, but never used them.
