Thanks mtv, yes, this topic would constitute a new thread on its own.
Those various Spauns you've been showing look like nice sturdy pieces of kit BTW.
OK, so when using that dual input V and H switch, coupled to a "twin" LNB (dual output, dual polarity), the switch itself then manages/fixes the voltages that are sent through the V and H ports respectively?
Because you have to somehow make it behave like it was connected to a dual-output V and H separate output LNB not so?
Two STBs can at some point for example send the same voltage (say both set to an H channel so sending 18V) up their cables, so this multiswitch makes them both then "connect" to the one input from the H port?
Long story short, I guess, does this multiswitch make a "twin" LNB behave like a separate-polarity output dual LNB?
And, it has something built into it preventing 26/36V DC accidentally running down only one of the input cables?
