As to questions I've raised and some that might enter your mind WRT satellite systems on the Anthem, just spoke with one of their techs, learning the following:
1) No surprises with In Motion...responds as described earlier in this post, depending on DISH or Direct TV, as chosen.
2) If you choose to add a portable to your rig, for those heavily forested sites you might stay (to locate the portable in a more open view), can do. Use the port in the bay for on shore cable. Disconnect the cable box that connects to the bay coax connector, in the living room area, and connect the cable to your satellite receiver. At that point, internal wiring in the unit will distribute the signal to all TVs in the same way the In Motion system would.
And I wasn't the first to ask...evidently, if you're hard core, can't miss TV, this provides the path.
