You need a DP21 for each tuner you want 5sats on (2 for a dual tuner, of course). Put your output of the DP44 into the DP21 Sat 1, then the 5th sat into the DP21 Sat 2. Then the out goes to your receiver. And as I said before, if you have a dual tuner receiver you'll need 2 DP21's as a DPP Separator WILL NOT work in this setup. So having two dual tuner receivers and a 211 you would not have enough ports on the DPP44 as you would need 2 separate lines for each 722 then another for the 211.
