True, but your discussion above is not making clear to Gdsmith07 what all he has and what he needs to get that H3 working. (At least I am unclear!) If that separator ever worked for a two-tuner Dish receiver, then that means his LNB is not just DishPro (bandstacked) but DishPro Plus (dual tuner over single cable). So, if he has a DIshPro Plus LNB/switch assembly, then what would he need to connect up that H3 and some Joeys? Will a DPH42 (which he has) be all that he needs?
And what about his LNB? He calls it a "dual", which is only good for one satellite location, and he admitted he probably needs to upgrade it to something, but does not know "to what". The pictures do indeed look like a dual LNB and not a twin. But in that case, a separator would not give you even two independent tuners.
He said in one post above that "it’s a single connection with two [outputs and] one eye cover". I have no clue what a DPH42 would do if connected up to only one DP dual (one satellite location).
