Almost got it.  It all has to do with the frequency at which it operates.
Hz, KHz, MHz.  The EE's at USF were working on this stuff and trying to make
a some high speed microwave datalink that could operate even if trees grew
or other obstacles grew in front of it.

Hmm... probably the way a FM radio works in one. We had one of those
metal storage containers boats use for storage behind the Ford
dealership i worked at. When it rained or snowed we went inside it and
smoked, the maintenance man kept a radio in it and that worked fine
through the metal box with the door closed.
