Re: [TCML] Smoke Detector Issues / Faraday cage

["Peter Terren" <pterren@xxxxxxxxxxxx>]

Agreed. I've tried the phone in the microwave before (works).
A Faraday cage with coarse mesh won't stop RF but that is not a high 
intensity signal and is broadband.  It will give RF interference but not 
kill anything.
What the cage does is stop is capacitative pick up on adjacent objects like 
you and other electronic equipment. Also sparks to mains wiring - nasty.  It 
also solves the problem of an RF earth.
