I'm in the process of building a new home. Will be getting either D* or E* service when we move in in a few months, depending on who is offering the better HDTV service at that time. My question is with prewiring. Will a multiswitch be able to combine the inputs from all LNBs and an OTA antennae onto one coax no matter what system I choose from either provider? I need it to handle an HDTV system and OTA since we likely will not have high def locals by satellite here for a while (small midwest community). I understand I will need two coax runs to any tv that will have a dual tuner receiver/dvr. Is there any need for more than two runs to any receivers available now or in the forseeable future?
