We didn't have a TV until the early '60s. My father bought a maybe 19" "Metal Cabinet" portable B/W TV from a guy that was remodeling a motel. It was well used, but still worked. He put up an antenna outside (after the next paycheck or so) and we picked up 1 channel, until the weather got bad and we could pick up stations from over 100 miles away. Didn't last long and back to one channel.
We had one of those on wheels. Back then the cords weren’t polarized, case could give you a hell of a thrill if you were grounded.
