I'm new here. Could someone help me out with this question ? I currently have a 18" Dual LNB with 2x4 (or 3x4 including antenna feed). I used up all 4 outputs with 2 IRDs and 1 Tivo. I would like to add another IRD and a friend of mine gave me an old 2x4 switch. I know I can't split the output feed to the IRD. The question is : Can I use a sat splitter and split the input feed from the dual LNB to feed to BOTH 2x4 multiswitches, since 2x4 locks odd and even on its 2 inputs. This is NOT cascading, because both 2x4 multiswitches would receive the same splitted signal simutaneously. Thanks.
