 What shall we do? I'm thinking in terms of real no-kidding copper screen. The old plaster and lath. You know how hard it is if you're in an old house that was built in the teens, the 20s, the 30s, the 40s? Pretty much started going away except the really expensive ones in the 50s. But before that, plaster and lath. Got a metal screen. Heavy. And it's also grounded. Grounded.
