It's funny how these things used to be on basically everyone's house. As a child I visited my granparents' farm and they had a massive monstrosity on top of their house that had a motor attached to it in order to rotate it in certain directions to better get some channels over others. This was in the 80's. Cable was something that not many people had and it definitely wouldn't have been available in rural farmland. I can only presume they are all on fiber-optic streaming services now. It's probably required.
