What I need is hdtv so I assume an eliptical triple lnb dish. I need to distribute sat (not all hd) to 9 or more tvs. I know I need a multi switch. However DirectTV told me that I need a switch with 6 inputs. I can only find switches with 4 direct tv and 1 antenna. Is four all I need to use. Also how would I go about hooking the lnb's to the multi switch I am not sure what the conncection side of the lnbs look like. Thanks for your help.
