TV Antenna???

I have no idea what most of this conversation means. All I know, is my house had a "BIG" antenna, on a tower, with a rotator, when we bought it 30 years ago. When the cable company raised my TV/Internet fees to over $125 per month, I cancelled. Did some work on a friends car in exchange for him hooking up the antenna. He installed a preamp on the antenna, ran a new cable, and a new controller for the rotator. We did have to add a additional amp, in the cable to feed the tv in the detatched garage. I get anywhere from 62 channels to about 50 channels. I don't know if some stations shut down at times, or if it is due to conditions.
PS: the cable company got me back as a customer for internet, by giving me their slowest speed (whatever that is) for $19 per month.
PPS: I have cell phone for $15 per month unlimited voice, no text or data.
That's all I need, so why pay more.
