I have heard you can build a cage as EMP sheilding and have it grounded. So it doesn't have to be a solider metal box. I am wondering if one could do so with say, chainlink fencing on the inside of say, your garage or an out building, and then have that grounded. And have foam matting on the floor of the structure.
Or, maybe a metal building like the metal storage sheds or even a quanset hut, again with a ruberized floor in addition to the building being grounded and of course not having any of your eletrical components you want to save touching or even close to the walls or ceiling.
Just something I wondered about, as when it comes to electronics if it doesn't work past the "on" button then I am lost
