AT&T Long Lines Oak Hill Tower, San Jose, CA 2021.
This unusual Brutalist tower was part of the former AT&T terrestrial microwave network that once carried the bulk of US long distance telephone traffic. The (long since disconnected) horn antennas are too big and heavy to remove.

@mattblaze It occurs to me that I know very little about this tech.
The microwaves were basically direct-beam transmission to other stations?

@mark @mattblaze fun fact: amateur radio can also still use microwaves. https://www.arrl.org/microwave
The circuits are kinda funky because the wavelengths are so short.
