Faraday Cage: How to Make on the Cheap

I wasn’t intending to contradict you - sorry if I came off that way - this is just what traceable open-sources say - and thought you’d be interested. In engineering terms 30 vs 50 (just a few dB among friends!) isn’t that significant, and doesn’t alter the remediation requirement or methods if you are concerned with the threat.

You didn’t come off as abrasive at all - I took it more along the lines of - Great - someone actually confirming what I remember. You also explained the results of a story I heard in Engineering school 30+ years ago!

That was about the only thing I remember from AC Machines class!

Would you then suggest unplugging the microwave, thereby making sure you aren’t connected to the house’s ground circuit? Serious question.

It does not matter if the Faraday cage is grounded or not. If you are doing a double-wall shield, then grounding the outer one stops static charges, but the inner one floats.

I’m not sure that an unpowered device small enough to fit in a microwave would be impacted by an EMP pulse, unless it had a long antenna on it.

Would you recommend taking the battery out of the devices before placing them in the microwave, or does this also act to protect the battery as well?

I take the battery out of anything I sore for a while. I disliked paying $30 for a fancy flashlight then finding a mess of battery corrosion inside.

I’m not sure if the lithiums and NiMH batteries can do that, but if I had a $60 FRS radio to store I’d pull the battery.

EMP will have no impact on a battery.
