    I know there are a couple of other threads asking for help with DECA, but I didn't want to hijack them. I thought I understood, but now I'm a little confused with this BS filter. I'm basically just looking for what goes where.
    I'm going to be majorly consolidating my system down. This is what it will look like before I deal with DECA or anything:
    SWM LNB to 4 way splitter (Outside). This will feed 2 H24s, and then feed another 4 way splitter. That splitter will feed 2 HR24s and a DECA adapter for internet access. Where in the line does this BS filter fit in? And do I need anything else?

    The Band Stop Filter always goes between the SWM (in this case, the LNB) and the first splitter. The purpose of the filter is to protect the SWM from the relatively high-level 500-600 MHz DECA signals that it wasn't designed for.

    I'm not sure cascading 2 4-way splitters is 'supported' (that's a 16-way split), if it doesn't work, you'll have to change your configuration.

    The filter?

    Yes.

    Any difference where it goes? Better closer to to the dish, or closer to the first splitter?

    Sure, with the right connectors and drip loops depending on location.

    It shouldn't matter... I'd put it adjacent to the first splitter. Note that all splitters aren't created equal... the original SWS-2, SWS-4 and SWS-8 splitters didn't have rubber 'boots' on the F-sockets, so might be less desirable to use outside. The 'green sticker' MRV-rated splitters do, as do Zinwell Split_-Z splitters currently available.

    P.S. Don't forget grounding. I'm not sure the configuration you describe (unless the first 4-way splitter is within earshot of the electrical service entrance) meets NEC.

    Put it in the LNB arm if it will fit.

    If he has a green label SWM LNB then the BS filter is not required. So in his setup he wouldn't need any BS filters as he doesn't list any receivers that are not MRV compatible.

    The DECA converter that connects to my router-what power supply do I need for that?

    The same model as the one that powers my SWM LNB?

    Given the costs why not just order it from DirecTV?
