Testing the Effectiveness of your Faraday Cage

An example of a signal strength reading from a $25 SDR receiver and using free software on your PC.  Essential for testing your Faraday cage.

So you’ve built your Faraday cage, and are ready to fill it with the precious electronic spares you want (need!) to protect against an EMP.  Well done.

But there’s one thing you really should do before closing it up and moving on to your next project.  Even if you’ve built a simple small and apparently 100% compliant cage, don’t you think you should check and test its effectiveness?  You’re placing a huge amount of reliance on this cage and its ability to protect its contents from an EMP, so isn’t it worth spending a bit of time and maybe a few dollars to check that it works as expected.

The interesting thing is that a Faraday cage is not an ‘all or nothing’ thing.  It isn’t like putting heavy blackout curtains across your windows and blocking out all the light from outside.  It is more like pulling a medium weight curtain across, and then having a searchlight shine on your window from outside.  Some light will get through, the key issue is how much.

The same with a Faraday cage.  It will reduce the strength of the EMP (the technical term is ‘attenuate’) but it won’t block it out entirely.  So how much attenuation will it provide, how much do we need, and how do we measure it?

“…You guys (the left) really want to stop pushing quite so hard. The political pendulum has never, in the history of humanity, stayed on one side of a swing. The back lash from over reach has always been proportionate to how far off center it went before coming back. (Hint, that’s what started the whole prohibition thing, and it’s also what started the 60s, was backlashes) Well right now we’re staring at a whole hell of a lot of the country (about 80-90% of the land mass, as well as about 50% of the population) that is FED UP. You really don’t want those guys to decide that the only way to fix it is to burn it down and start over… REALLY! Most of these folks are vets, and the children of vets, they’ve had guns in their hands since middle school or before, or they’re still serving either…
