Looking for answers before installer comes. I have an existing dish with a DPP+ lnb which fed three wallys originally. I have ordered a hopper3 and one joey. Additionally I would like to add a wally which I own. I'm thinking that a DPH42 switch could be added with port one going to the power inserter and the wally and port two going to a hybrid solo hub and the hopper/joey combo. Of course keeping the DPP+ lnb. What do you think guys. Will it work that way?
