@[email protected] Many years ago there was, I guess, some kind of microwave link atop a hill above San Rafael (Marin County, north of San Francisco). It wasn’t a concrete tower like this but was some kind of metal frame supporting four horn antennas pointing in the four cardinal directions. From a distance it looked like a conference table surrounded by four chairs. I’ve looked for a picture in vain. I think it’s gone now.
@[email protected] This video from the open space district that manages the area has a still photo showing the antenna atop the building:

It’s interesting that this antenna was exposed, whereas others, like the ones atop Mt Tamalpais in Marin (north of SF), had “golf ball” enclosures:
