    I want to setup two SWM16s as i have 10 HR24s. Do i need a polarity locker as well and i read that i need two DECA's so i can do MRV across all the receivers. Exactly which DECA piece would that be? is is deca broadband router that i need two of?

    Thanks!

    2 CCKs [broadband DECA] with one on each SWiM.

    Unless the coax to the LNB are very long, or you're not using splitters that are dual power passing, you shouldn't need a locker, since each SWiM will power the LNB.

    Ok, here is a question VOS.....


    I am going to be doing a setup the similar as this for a family member 10 HR24 and 2 HR25.. they ordered 2 SWM-16 units but, forgot to order splitters that are dual passing.:bang

    The only chance that i have to get this done is Thursday so, my question is will it work to use a WB68 instead of the dual passing splitters?

    Will it? yes, but I'd look at this as a "temp fix" and replace with splitters later.

    I'm curious what you find wrong with it. Is it just because it would be more unsupported, or do you see a technical problem with it?

    Six years ago, Zinwell used to have a pdf showing a WB68 feeding two WB616s, so it isn't a case of a "technical" problem.

    It simply comes down to a chip can fail long before a stripline on a PCB will, so there is significantly less chance of ever having a problem with a splitter.

    Thanks, that's what i was looking for... yes it will be a temp fix.. in fact i think i may have him sell the swm 16's and put in a swm 32

    Curious as to why?
    The -32 has no provisions for DECA networking.

    Simply just to only have to worry about one SWM... I did not know it didn't have provisions for DECA networking. I guess two SWM16's is the way to go then...

    I'm still trying to see the need for 12 receivers in there home... there's only 8 people there:confused:

    Yeah, sometimes it's hard to figure, "but" I need at least 2 DVRs for myself. Add another TV and there's another receiver.

    Not sure of the ages of the 8 people, but if they're all recording different shows, 12 might just be needed to "keep the peace".

    I can only imagine what the U-Who commercial would look like with only being able to record 4. :nono: :lol:

    A little off topic; I was speaking with a tech a few weeks back and he started spouting some "garbage" -- said that he was installing SWM32's in residences for folks. I asked him how whole home was working out over the SWM32; he said "fantastic, the SWM32 is much faster for remote trickplay than the SWM16." :lol:

    As you might guess, he was not only a liar, but also a horrible tech... :nono2:

    Might not want to call him a "tech", as installer might be even too high a praise.

    Curious though;

    As done with diplexers on the combined four outputs of 2 parallel SWM-16s making their internal DECA crossover networks unneeded, http://www.dbstalk.com/showthread.php?t=207005

    Why can't you couple the four outputs of a SWM-32 through diplexers in the same manner for WH connectivity?

    Other than linking to the wrong diagram, but knowing my own work, a SWM-32, two SWM-16s, & 4 SWM8s can be combined that way, but the PHY loss increases 5 dB over using the internal crossover in the SWM-16.

    Huh? :confused:

    The loss "increases 5 dB" over using the internal crossover of the SWM-16?

    I thought you wrote the opposite?

    From the PDF document posted on the SolidSignal discussion board:

    I don't work for SolidSignal, nor did I write/create the pdf.

    My testing has shown:

    1. The -16 internal crossover has 6-7 dB loss.
    2. Bridging [with a short coax] two NAS diplexers together has 5 dB less loss.
    3. Adding a 4-way green labeled splitter to combine more than two diplexers adds 10 dB.
    4. The "net increase" of loss is 5 dB more, over using the internal crossover.

    Do the issues with the SWM-32 and whole home networking still exist?

    I had a technician (or an installer) come by last week and try to fix a signal issue. (Dropouts on 101 and 103). After moving the dish and than swapping it out; he told me that my current setup needed to be adjusted.

    (I have 2 SWM-16s with two Decas and the whole home network has been very solid with 4 HR-24, 3-HR-22, 5 H24s)

    He said he was ordering a SWM-32 and he is coming back this week.

    I don't want to lose Network features so should i not let him install the SWM-32?

    Any input is much appreciated

    Swm32 will never work for whole-home, because it isn't designed to. There are some workarounds but they are unsupported.

    A CCK on each leg would be ok and supported as this is how it would get setup in an MDU situation using BS filters to stop from going to other units if applicable.

    With that said using a SWM 32 in a residential sitaution is unsupported so your statement there is correct.

    I don't like that image as it has a 4 way splitter for just 1 receiver.
