FIELD: physics.
SUBSTANCE: invention relates to protection of confidential information. Essence of the invention is increase of efficiency of protection of confidential information from leak through connection lines of internal arrangement, which are part of the distributed random antenna. Method of information protection of a distributed random antenna element in the form of a cable connecting line of internal arrangement by means of a magnetic shield, which reduces intensity of an electromagnetic field created in an external medium by a signal circulating in a distributed random antenna, is characterized by the fact that the magnetic screen is in the form of a spiral tape of amorphous cobalt alloy 71CNR and is placed on the outer surface of the coating of the cable connecting line, which is part of the distributed random antenna.
EFFECT: invention can be used for protection of radio systems integrated by the distributed random antennae term.
