ALUMINUM FOIL WRAPPED ENCLOSURE
Aluminum foil if carefully wrapped around a non-conductive plastic encased distress beacon
can be used to adequately shield the distress beacon to prevent inadvertent significant
radiation of the signal being tested. It is important to ensure all ends and edges are securely
and smoothly folded together, that there are no tears or rips in the foil, and that any
connection between the tester and the device or signal probe located inside the enclosure is
making a good contact with the aluminum foil used to shield the device.
STEP 1 TAKE A PIECE OF FOIL SLIGHTLY LONGER THAN THE LENGTH OF THE DEVICE
