If you live in a state where you are being forced to install a cancer causing spying smart meter on you home you need to protect yourself. The first step is finding out how bad your exposure to microwaves are. I have links below to a company that I have personally dealt with and have found to be top notch. This is a German company and what is interesting is that the German's have hard wired their smart grid vs using microwaves systems because of concerns about the health effects of microwave exposure. Looks like they already know something we will unfortunately learn the hard way if we don't protect ourselves.
