I purchased my residence in 1987. It had a tower with three 10 foot sections, the bottom buried in the ground, and was also supported to the eave of the one storey house. It had a small VHF antenna and a rotor. My neighbour gave me an old controller with a rocker bar. I never did get the wiring 100%, but by moving two wires I could rotate the antenna.
In October 1995, the antenna was replaced VHF/UHF extreme distance, which is still in use today. The rotor was also replaced.
Devices that I’ve had, or still have, that were/are OTA antenna rotor friendly.
Meaning, I’m able to add new channels when the antenna is rotated, and previously located channels are kept.
NOTE: If I remember correctly, electing a brand new scan, not an add channel scan, would delete previously found channels with every device.

The first TV that I hooked up to the antenna was a 19 inch TV, which might have been a JVC.
I have 2 Legacy 4 tuners, 1 HDMI 2 tuner (which is hooked up to a Sony TV in the basement and is not used), 1 Gen Four 4 tuner.
When I bought the first Legacy 4 tuner, I couldn’t believe that the unit would not allow the ability to add new channels, and retain the previously found ones.
