A while ago, there was a coax cable connected to a power AC ( as an example online) in one of the small rooms (closest one to the main coax cable to the satellite dish and before its splitter in the attic) for the previous owners' Dish TV service. Is this a preamp? This was removed, so maybe this is why OTA does poorly in the rooms since this premap was removed? I wonder if we should put it back (not sure if it is compatible with OTA?), and it will work better?
