Bonus microwave tower photo: Western Union Tenleytown Tower, Washington, DC, 2020.
The first commercial terrestrial microwave network wasn't actually AT&T, but rather Western Union (the telegraph/telegram company).
A few remnants of the network survive. This hexagonal concrete tower, built in 1947 down an alley in Tenleytown, Washington, DC, was part of the first experimental link in the network. The cupola of the tower is actually a plexiglass radome concealing microwave antennas.
(Western Union today is mostly a retail money remitter and check cashing outlet for the unbanked, but back in the day was a significant part of US telecom infrastructure, providing data communications including telegraph, teletype, and telegram services).

@mattblaze I thought the only purpose of Western Union today is as a vehicle for scamming elderly seniors out of money. 🤔

@ai6yr Pretty much. Whatever was left of their original business model collapsed with the Internet.

@20002ist Neat. Will have to check it out. I love "Department of Terrestrial Magnetism". So specific.

@20002ist @mattblaze Ooh, and right near Rock Creek Park.

@mattblaze @20002ist That department is referenced several times in Rhodes' "The Making of the Atomic Bomb".
