Old over the air "cable" tv system in Saginaw

[EC-7]

I'm trying to find out info on an old over-the-air, multi channel "cable" tv system that was in place years ago in Saginaw County. I believe it was broadcast from the towers near the mall.
I think they used around the 2.4Ghz band. They used Pacific Monolithics antennas and down-converters.

Im looking for info on what freq they were on or the down-converter freqs.
Or does anyone know what company it was? I know a lot of people had them, but its been out of service for years, as I've been told.

Here are the antennas they used.

Multichannel Multipoint Distribution Service - Wikipedia, the free encyclopedia

2.5-2.7GHz.

You can also look up FCC part 27, which covers this. Other than mention that each "channel" is 6MHz wide, I didn't see anything in my quick look that spec'd out exact channel specs.

Was it I" It Selectvision" or "On TV"?

My parents had It TV and I think it went away around 1985. There was a box with an A/B switch ( your two movie channels) and a descrambler box which I think had a 4 digit scramble code that changed monthly and you had to turn the dials to the proper code.

But I was only about 8 at the time but that's what I remember.
