I'm building a Gu-81 tesla coil and i want to build a faraday cage around it, but any time i search on google for a anything related to a faraday cages i just get a bunch of conspiracy nuts making "tutorials" of them wrapping their phones in foil because they think their phone is mind controlling them or something. So where can i find good info on faraday cages and just RF stuff in general that isn't a bunch of conspiracy misinformation?
