...a coax to each TV location should stay, so I called DirecTV and ordered two RF remotes and mounts for their boxes....
This project should be a commercial install, not a residential install, and some commercial equipment is different from resi equipment. Whenever you go RF control with a commercial DirecTV box, remember to verify whether the receiver has a built-in antenna for the RF remote. Not all of them do and that's an irritating thing to discover on site!
