Tin foil hat radio with a metal bucket. The AM radio is completely inside a metal enclosure. This leads to a noticeable reduction in signal strength received by the AM radio. The efficiency of a metal enclosure in blocking electromagnetic radiation depends on the thickness of the foil, as dictated by the "skin depth" of the conductor for a particular wave frequency range of the radiation. For half-millimetre-thick aluminum foil, radiation above about 20 kHz (i.e., including both AM and FM bands) would be partially blocked, although aluminum foil is not sold in this thickness, so numerous layers of foil would be required
Tin Man Is Down 219 differs from the 250+ bodies, laid out in rows in a large hall, in the final minutes of "The Choice". This is the first episode of the series not to feature Damian Lewis as Nicholas Brody or David Harewood as David Estes due to the former character now being a fugitive from justice and the latter's death in the previous season's finale. Scheduled head-to-head against the "Breaking Bad" series finale, the original broadcast of "Tin Man Is Down" had 1.88 million viewers, showing an increase over the previous season's premiere episode.
