I have designed a lot of things with Faraday shields.

If you have the money [ uplinks for to satellites on AIR FORCE ONE, USAF jets, and USN submarines] you get MU-Metal

That can even sheild out low frequency. [important to the submarines]

If you are cheapskate [like one defibrillator in an injection moulded enclosure] you get conductive paint sprayed in the inside. The ground connection is touchy feely.


But mostly in the middle cost [F-16 radar warning, ect] you get a hogged out or investment cast Aluminum alloy enclosure.


For Halloween, you get an Aluminum foil hat.
