    Directv just installed a SWM 3 Dish/LNB, which goes to 8 Way Wide Band Splitter and all is working. My question is if I go over 8 tuners can that signal be split? I asked the installer and he said yes with an additional SWM 8. Is this correct, because the dish has its own multiswitch built in.

    No, you will need a legacy LNB and a SWM16 to exceed the 8 tuner limit.

    Or a legacy LNB with the four outputs split going to two SWM-8's.

    However, matt's suggestion is better as the SWM-16 would be much easier to setup and can bridge a DECA network as well.

    Yes, there are many possible combinations but the take home point is that there is no way you are going to get more than 8 tuners* out of a SWM LNB.

    *9 tuners if you want to be technical about it, which I'm sure you do. :D

    Correct, if you don't use the 3 legacy ports on a swm8....

    It's a dedicated guide data tuner. Look at your SWM strengths on the IRD's signal meters. ;)

    No, it's not really a tuner in the same sense as the other eight, which are in the receivers. It's a dedicated guide SWM CHANNEL. Every tuner connected to the SWM receives it.

    We're getting down to splitting hairs here, "but" each receiver has a network "tuner" that it a narrow band tuner for the guide data. The DVRs actually have three internal tuners, two for recording and one just for the guide data and other info in the stream.

    Agreed;

    "Splitting hairs" indeed ... :D

    But to engage in such "hair splitting" just once more. I guess the more accurate way of explaining it is that the basic SWiM module or LNB uses up to eight separate RF channels to distribute programming to as many as eight independent satellite tuners in aggregate (up to two for each DVR, 1 for a STB receiver).

    A ninth RF channel (~974 MHz) from the SWiM is common to all receivers and is used by a special narrowband "Network Tuner" aboard each of them.

    Correct. But for normal explanations (how many tuners can you drive per SWM LNB), it's accurate to say 8 tuners, not 2+1 per DVR and 1+1 per receiver which is correct from an electronics perspective. And certainly not 9..

    I'm not going to try to split this hair any finer.
    ALL SWiM outputs can handle eight tuners and no more.
    The SWiM-16 & SWiM-32 have multiple outputs, but are still limited to EIGHT tuners on each.

    Does DirecTV have a good solution to 9-tuner installs?

    For swim, they will throw a swim-16 at it. For legacy, it's just, "show up and figure it out."

    It's dicey to chain 6x8's off each other. It only gives you 12 outputs, and if the 6x8's are slightly bad, you will have errors.

    The proper solution, which is to install 4 power-passing splitters, means $12 in additional material costs, and it's not clear that DirecTV reimburses for this.

    So, what do you guys do on 9-tuner installs (aka upgrades)?

    SWiM-16 it. Legacy receivers get replaced with SWiM capable ones.

    Yeah? What if they have a bunch of D-11's?

    In a conversion to SWM, D11's would be replaced with D12s.
