Funny story: When I bought my first house in my early 20's, I was too poor to even consider cable. Heck, I didn't even have any fully-functional TV's, they were all hand-me-downs with various deficiencies. One without sound, another without UHF... you get the idea.
So, I head to Radio Shack to buy a reasonably good antenna, as my house was well-located near the top of a south-facing hill, about 40 miles north of Philly. Despite the distance, I figured I'd actually pull in a few stations clear enough to at least see the news. I was working full time + part time school + renovating the old Victorian house, so there wasn't much time for sitting and watching, anyway.
It just happened that Radio Shack was discontinuing several of the antennas at the time, since cable companies were stealing all of their antenna sales, and they had this absolute monster of an antenna on sale for the same price as the more modest one I had planned to buy. If I recall, the thing had a wing span of 16 feet, and an overall length around 30 feet. It looked like a damn ultralight aircraft.
So, I bring the monstrosity home, and set it up in the attic of my carriage barn. It literally
filled the whole attic, you had to crawl under and around it, just to get up there and access anything. Comically huge thing.
But... I found I was able to pull in channels from Baltimore up thru NYC! The Philly stations were so clear, they might as well have been on cable, whereas the Baltimore and NYC stations were a little grainy (like what I had expected for local channels). I had access to almost as many channels as if I'd paid for cable, but for free.
Eventually, the thing took a lightning strike, which blew out every connected device in the house and barn. After that I had no TV, until my wife moved in and signed us up for cable.
