heck, you can have more than one receiver on at a time even with a single
items needed
-high frequency splitters (up to 2GHZ, not the 900MHZ crap)
-DC block
-cable
hook the high frequency splitter to the LNB output (they make 2 & 4 outputs)
Sopme splitters ahve a "power pass" on one side. If it does, then the DC block is not needed. If its "all power pass", then the DC block is needed
Hook everything up. The receiver that doesnt get the DC block is the main one. It will work great for G10 or T5, that MOSTLY use one polarity. The main controls the polarity. I ran my Pansat and Viacast off one single LNB for a while doing this
crude drawing attached...the "D" is the DC block
