It is possible for metal objects to reradiate RF. I have one of those
"zap checkers" that snif RF in a broadband sense. Many metal objects in
my home office reradiate PC hash.

Tikaboo Peak sits in a constant RF field of considerable strength. It
is probably the from the gear on Badger Mountain.

The zap checker comes in handy around Groom Lake. I can detect when
they fire up the radar on Bald Mountain. You get a ping every 12  or so
seconds. I keep meaning to turn on my radar detector at the same time
to see if it gets a hit.

Waiting around my dentist's office, I read what is probably the current
issue of Popular Science. There was an article inside that indicated
that those foil hats don't shield all that well. There was a claim that
the foil hat actually increased the signal level in the cell phone
frequency range (800 to 900 Mhz I presume).

Absolutely true, as demonstrated by a series of experiments at MIT:

Of course the CIA knew this many years ago and cleverly spread the
rumor that foil hats protect against mind rays, when the truth is just
the opposite.  That way, Seekers After Truth have been rendering
themselves more vulnerable to Government Manipulation.  Typically
fiendish, is it not?
