What's the best HD antenna for an apt with no roof access? Weak signal!
They really screwed over a lot of people when they closed the analog spectrum for TV. Like my friend who lives in a second floor apartment in a medium-sized city, not far from 2 TV stations, who still can't get a signal with a portable antenna. I can get a weak signal at ceiling level (she's on the 2nd floor) but not good enough.
