I am pretty new to this industry so this question will probably be easy for most to answer. What exactly is a SWM signal and how is it different from the signal a conventional multiswitch uses and outputs? If not already answered from your description above, why can one use a splitter after a SWM but not use a splitter after a conventional multiswitch? I was told that it does not even have to be a SWM splitter. From my basic knowledge I was told that the different voltages that receivers send to the LNB would "interfere" with eachother after passing through the splitter on its way to the LNB. Does this "interference" occur only when the voltages are different or does it occur even if they are the same? Why is this "interference" not an issue with a SWM? Is it because each line from this multiswitch can carry up to 8 tuners? Thanks.
