One of us used to climb up on the roof of our two-story house and turn the antenna while another of us watched the effect on the screen and shouted updates to the one on the roof. Our parents probably were horrified at the danger, but as pre-teens and teenagers we didn't know any better.
Now I have an indoor antenna, a very thin circular gadget that hangs on the wall facing the transmitters on the hill across the valley. I can get all of the channels I want, perfectly clearly, and it was a one-time, low-cost expense.
