Growing up in San Jose, it seemed like we had a lot of channels, even back in the 1970's. We could get channe 3, 10 and 13 out of Sacramento, sometimes Channel 6. Not perfectly, but enough to watch. All the stuff out of San Francisco, and some stuff out of Salinas, also.
Of course as kids, it was all channel 44 and channel 2 after school, that's where all the cartoons were.
Round about the early 80's, my brother built one of the bootleg HBO dishes. We had a neighbor that was an EMI/RFI engineer and helped my brother. They printed up the circuit board for the down coverter and used an old variable power supply for the tuning. Our neighbor had some guy up in Oakland that made woks and they just adjusted the machine to make parabolic reflectors. For a while we got HBO for free when it was transmitted over the air on microwave. Of course one day we got a letter telling us it was illegal and to stop doing it. We ignored it and finally they went scrambled or switched to the cable system.
We were pretty amazed by a neighbor who had cable TV. Back then it was Gil Cable. They had an A and a B feeder, so some channels were on the A feed and some on the B feed. You had to have a coax switch on top of the TV to select. I think there was something like 16 channels per feed.
I moved closer to Monterey, and I can get stuff out of San Jose sometimes, but a lot of digital channels down here. With the sub channels, there's a pretty good selection. We gave up our satellite TV years ago and just use the antenna up in the attic. Between that and internet, no need for anything else.
