Would a shipping container a good Faraday cage ?

[money-dog]

Was wondering if a shipping container (18 wheeler style minus the trailer frame) make a good Faraday cage ?

nope.

It might if you put it underground.

Why not? I was told that a good test is to place your cell phone inside your cage and try to call it. If it doesn't ring then you're good to go.

Why not? If it is metal on all sides and grounded?

At best it would make a very poor one. You would need to spend a good amount of time bonding all of the pieces together electrically and even then it would be marginal. You could build a conductive mesh cage inside of it and bond that all together.

An EMP, which is what is a Faraday cage protects against, will induce so much electro magnetic current into the air and ground in a very short time (milliseconds) .
The only way to ensure an EMP will not penetrate the area to be protected, is to cover the area with a copper mesh. Like a chain link fence of copper or something similar.
This open linked design redirects the energy and slows it down.

If we get hit by an EMP, keeping you cell phone working is not going to be a priority.
