Three posts here speak of the Faraday cage needing to be earth grounded. I searched and searched the net a few months back to prove the case that the cage had to be grounded to reject RFI. The only thing I could find was that it did not... Example, CDP, DVD players, TVs, and radios. Two wire cord and plug no equipment earth ground. CDP and DVD players just a floating metal enclosure, a Faraday cage.
