My father worked in defense. He shared lore about the genesis of tempest, the requirement to use faraday cages to protect secrets, gear, etc.
The story goes that some kind of red team set up shop down the road from some missile tests (or something) with some simple gear. Afterwards, they shared the launch codes used, shocking all the brass. Hence the need for shielded comms.
