I did some research and just want to confirm if this what I need to convert an existing AU9S (Slimline) connected to a 5 LNB (4 wire type) to a SWM (5 LNB or 3 LNB) setup? replace the existing lnb (4 wire type) to an SWM type LNB and re-align dish. add a 21V Power Inserter to the single cable line coming out of the new lnb. add a 4-way or 8 way SWM splitter after the power inserter so additional receivers can be hooked up later. Is that the way to go?
