- I bought this 1960's vintage Alliance Tenna-Rotor model U-100 on eBay from a guy who found it in a box in his father's attic. It had never been used. The plastic cover for the electrical connection board was missing, but I'll be making a 3D printed replacement for it. The Channel Master CM-5020 antenna and the Tenna-Rotor are mounted in my garage attic, where it does a great job of picking up both TV and FM radio stations. I bought the Tenna-Rotor rather than a new digital unit because I wanted to hear the ca-chunk of the solenoid in the control box like back in the old days in my parents' house (I was born in 1958).
My dad had installed one of those over our Akron-area home during the era of the ironclad rule for NFL home-game blackouts to watch Cleveland Browns' home games broadcast from Columbus or Steubenville. The tenna rotor was on a tower, that went high over a very large, 3 story home with a slate roof. It worked sometimes, the picture was snowy usually. At night during better atmospheric conditions, we could watch the "Woody Hayes Show" from Columbus. Before cable, satellite, and the internet, you might say we made our own fun.
It was fun to hear a tenna rotor again! We had one when I was a kid. I was always moving the antenna around trying to drag in far away (actually probably less than 100 miles 😊) stations. Many times I watched "I Love Lucy " reruns that I could just about see through the "snow" but I could hear it. Thanks for that little trip down Memory Lane!
Nice U100 & will last forever in attic👍👍
These systems are becoming impossible to find. Finding control boxes is easy because people find them in estate close outs, but nobody ever saves the rotators from the chimneys/rooftops. I'm experimenting with the vintage Channel Masters because the rotator and control boxes supposedly use the same motor inside both parts, so in theory you could harvest a motor out of a spare control box and then you just have to build some kind of rotator system to use the motor. To complicate things some of the CMs used a fuel sending unit gauge system to indicate position.
I'm looking for a model U 110 4 wire drive motor for the mast, l already have the compass dial controller box, anyone out there have one to sell???
What about coax cable connected to antenna, is it going to be twisted? Is there brake on the rotor?
Some of these systems have "stops" so you can't rotate them more than 360 degrees. When it hits the stop you can only reverse direction.
