    For much of the 20th century, the backbone of the AT&T “Long Lines” long distance telephone network consisted primarily of terrestrial microwave links (rather than copper or fiber cables). Towers with distinctive KS-15676 “horn” antennas could be seen on hilltops and atop switching center buildings across the US; they were simply part of the American landscape.

    Most of the relay towers were simple steel structures. This brutalist concrete platform in San Jose was, I believe, of a unique design.

      The San Jose Oak Hill Tower is unique in a number of ways. This particular concrete brutalist design appears not to have been used anywhere else; it seems to have been site-specific. It sits atop an underground switching center (that was partly used for a military contract), which explains the relatively hardened design.

      Today the underground switch is still there, owned by AT&T, but the tower space is leased to land mobile and cellular providers. The old horn antennas at top are disconnected.

        I think there might be a similar tower in Norway, south of Stavanger - NATO building of some sort associated, IIRC. I never got a good view (other people were driving), so I am not certain.

        With a few exceptions (mostly towers atop downtown switching offices in populated areas), no one was trying to make any of this utilitarian communications infrastructure beautiful. It was form strictly following function, built to be reliable and rugged.

        But there was, I think, quite a bit of beauty to find in it. I wonder if we’ll look at our current neighborhood cellular towers, now often regarded as a visual blight, the same way decades after they’re (inevitably) also gone.
