8 Common Faraday Cage Myths
by michael Major

Faraday cages have gained a lot of popularity for preppers and survivalists who want to make sure that their electronics remain intact in the event of an EMP or CME.

The problem is that the popularity of Faraday cages has also generated a lot of myths and misinformation that anyone wanting to build one must sift through.

What to Place Inside of a Faraday Cage?

8 Common Faraday Cage MythsThink about any complex electronic devices you would like to have available to you in a grid-down situation.

For example, hand-crank radios, amateur radios, solar generators, computers, battery packs, flashlights, etc., all could be rendered useless after an EMP.

Placing these inside of a Faraday cage will shield them from the devastating effects of the pulse and result in you having more tools to increase your survivability post-collapse.
Myths and Misinformation

Since we have thankfully never had to live through an EMP attack, there is no accurate first-hand information on shield electronics from an EMP.

However, there is a lot of research and experiments that have been done on the subject that we can base our Faraday cage designs off.

The lack of real-world examples of people designing and building Faraday cages and successfully using them to shield electronics during an EMP attack leads to myths and misinformation.

While there are dozens of Faraday cage myths, I have collected these five that I see brought up repeatedly.

All You Need Is a Metal Box

8 Common Faraday Cage MythsI have seen a few posts online that suggest that all you need is a metal box or trash can to place electronics inside.

While this is a good start, fabricating a practical Faraday cage requires a little more work. The critical factor is that the exterior must have no gaps in its conductivity.

This means that the lid and the container’s body must be connected electrically. Where the lid and body meet, there must be a bridge for the electrical energy to pass along.

Bare metal may be enough in some cases, but using conductive tape to seal the joint is better.

The equipment inside also must be insulated from the shell of the cage. This can be as simple as a cardboard, rubber, or wood layer.

The key is that whatever you place in the box will be electrically insulated from the cage’s metal.

Faraday Cages Need Grounding

8 Common Faraday Cage MythsWhether a Faraday Cage requires grounding or not is a topic of hot debate in prepper and survivalist circles.

The truth is that it does not need grounding to be effective.

Still, you should consider grounding a Faraday cage anyway.

The advantage of grounding it is ...
