I don't think that is the main reason at all Mike. Yes, it has been said that the 42 switch would allow 2 H3s but there could be other uses for it. Just the terminology DPH-42 tells me that the switch, itself, has the hybrid function built in to it. The H3 needs that hybrid function to get 16 tuners down the pipe to the hub. So that, today, means that the Hybrid LNB is required. That hinders many dish configurations required for various subscriber needs. With the hybrid function built in to the switch you can have any dish configuration needed using standard LNBs.
