    i had a retailer contact me about getting a commercial account up and running for him. The building has 16 rec. (311's). Initally, I installed 2 1000.2 dishnetwork dishes. Each dish is running to 2 SW44 switches that are cascaded. The power insterts are in line on the first ports of the 44 switch. Everything works fine during the daytime. During the night when ll the tenants in the apt power up the boxes, rec start to loose channels, freeze up. I tried throwing up 2 more dishes to run ech 44 switch and i hve the same problem. Can Anyone help please

    Why are you using two 1000.2 dishes? Are they connected to each other in any way?

    Never mind on my previous reply. I reread your question. It kind of sounds like a cable problem. This will happen with RG59 or poor quality RG6. I have also seen some strange things happen when there are grounding issues.

    Isn't the SW-44 for legacy LNBs? Wouldn't DP34's be better for this situation?

    You also mentioned cascading. The SW-44s I've found have satellite inputs and receiver outputs ... no outputs to feed another switch. It sounds like you were using them like normal cable splitters.

    I agree that SW-44's would not be ideal for the setup. The 2 dishes would be needed because you can only trunk 3 switches together (which is only 12 outputs, where 16 are needed). It does sound like a cabling issue, whether it be set up wrong, or possibly a bad power inserter. I think the best way to do this would be with DP34 switches, or DPP44 switches.

    Also, the SW44 only supports 2 satellite locations, are you sure that you're not using a DPP44?

    I really need to read the posts more carefully.:grin:

    You are correct about the SW-44 they are not cascade-able and they are for legacy. If it really is a SW44 and not a DP44 then there will be issues.

    I'm sorry I am using dpp44 switches not sw44. I just can't figure out why it only messes up at night

    Are you using the existing cable or did you run new RG6?

    Something has to be defective, ever replace the LNB's or any of the switches?

    The crazy thing is that there are two buildings that are completely separate and are having the same issues

    I would say the best thing to do from this point is replace everything until the problem is fixed.

    First issue: you aren't *supposed* to use a 1000.2 LNB to feed external switches. Yes, I know it often works in a residential setting where cable lengths tend to be short, but as cable length increases, things become less reliable. You should be using the 1000.2 "W-adapter" and 3 DP Duals. The other advantage of this method is that you can use a single dish, and use both ports on the DP Duals, one line to each switch, to run a max of 6 DPP44s.

    Second, where exactly are the power inserters? If they are in the apartments, you have big problems. Customers love to unplug those things.

    I've used this setup on hundreds of units and your last paragragh is exactly why I use DP34's. The OP's requirements would be a perfect candidate for a
    DP34 setup.

    This sounds like the most solid advice. Again I would test the existing RG6 if you are not the one who installed it.

    The night part doesn't bother me ... as you stated, that is when people come home and turn everything on. If I told you that my car has a rattle when I drive it but is fine when parked in my garage wouldn't that make sense?

    You mentioned grounding ... how is the building's electrical system? Everything on at night (including lights, TVs, the occasional microwave use, phones, computers and other electronics) might be causing a draw.

    I like the idea of using DP34s instead ... and that would be all you would need to feed 311s. Removing the DPP44s would remove the option of using dual tuner receivers in the future. Dallas locals are all on 110 ... are you feeding 129 for future HD?

    If you do use the DP34s then it would be very important to not use the the 1000.2 LNB. It is not compatible with any Dish Pro switches.
