Electronic Security

I have been lurking for a while, trying to learn. Someone asked about electromagnetic shielding. I remembered an article in Popular Science. It was July 1989 on p. 87. It described a _fabric_ which provided 100 dB of shielding. I have not used it, but thought I would pass on the reference. It is called Saf'n'Shielded and is produced by International Paper. Hope this helps. -- {---------------------------------------------------------} J. C. Allen Ass't.
