A microwave oven can also be used as a Faraday cage. Remove the power cord completely, place items inside and seal the vents and hole where the chord was with foil, mylar or metal mesh. Naturally, this is a microwave that is already dead as once you remove the chord it is no longer good for cooking.
A galvanized trash can or a large aluminum stock pot can also be used as a cage. You just need to be sure you have a good seal and there is metal touching metal all the way around the opening. As always your items being protected cannot come into contact with the metal.
Items to place in your cage may include, HAM radios, battery powdered radios, fuses, batteries, spare parts for tube radios, replacement components for your generator, and any other item which will be able to work separate from the electrical grid.
