There was a time when C band satellite shared spectrum with terrestrial microwave. In a town I grew up near, they had a hard time with their first HBO TVRO installation due to a Pacific Northwest Bell radio a few blocks away.

You could put a very wide range of frequencies through them and with the correct feed, you can have many radios and many different bands on all at the same time.

The ones closer to major metro areas have more tenants and more value to their new owners. The Long Lines sites that were built solely as a means to get a PTP relay over a major mountain range are amazing. Built with massive diesel tanks and ventilation intakes 18' off the ground due to snow pack. These ones have the original horn antennas and not much else, maybe some VHF/UHF omni radio repeaters for forestry/national parks.

It was also one of the ground sites for the Air Force 1 secure communications network, I don’t know if that’s still operational, I think maybe it is. Last I heard DeKalb, IL is still an active fiber POP. Tower is not used, but they won’t least space or sell it. It’s right in town and not a very well kept secret.
