THE ABANDONED MICROWAVE TOWERS THAT ONCE LINKED THE US

Mods fix the title. OP don't post titles like this in all caps this is HN.

Fun fact: A lot of these towers are now used in HFT; they have even lower latency than fiber laid nearly as the crow flies.

One of these towers is near my house. The big microwave "horns" were removed about 5 years ago and it's used as a cellular phone tower now.

I can remember in the seventies you could put a small dish up on your roof and receive TV channels through microwave. It was a competitor just as our area was being wired for cable TV.

In the BBS days a few of us wondered if the then dormant network could be used for email and perhaps a nationwide BBS network.

Some of those towers are still out there in Michigan at least.
