The Faraday cages I used to use in a lab testing RF devices, used copper screen.

This is actually really nice.

Even if human rf sensitivity were real, tin foil would work.

You're sharing actual faraday cage material.

Real EE stuff. Probably better than the cage material that I know that lines MRI rooms.

Yeah, it was some crazy stuff. We used to do mobile handsets, GPS, WiFi and other consumer electronics testing.

We've be locked in cages like - https://engineering.ssl.berkeley.edu/faraday-cage/

Tinfoil works quite well, after aluminium has pretty good conductivity. The problem is not leaving any gaps that are too big in any direction, or you just build a slit antenna by accident.

This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.
