In this multi-part article, I am sharing a better solution for protecting sensitive electronics stored in metal military surplus ammunition cans. There are many references for making a Faraday Cage on SurvivalBlog. Some references go back as far as 2005. One solution was proposed in 2006 that required the removal of the rubber gasket on ammo cans and replacing the seals with a conductive material (stainless steel or steel wool). Other articles suggested the use of a galvanized garbage can that is sealed up with conductive metallic tape, or an open head steel drum, or using an old microwave oven and a metal cabinet. I have read and researched many great comments and feedback on the effectiveness of these EMP protection measures.
Previous Proposals
All of the proposed solutions are more or less effective. Some have been tested using some sophisticated test equipment that gives you some confidence that different approaches will be effective. But unless your solution is tested, then it’s still unclear if or how effective your solution will be when needed in the future.
The problem with many of these solutions is that each didn’t make it convenient to access. Perhaps it required the metal container to be resealed, while other solutions were sometimes big and bulky, or untested and may not be reliable in the worst-case scenarios.
