FIELD: radio engineering and communication.
SUBSTANCE: invention relates to radio engineering and is intended for use on radio communication lines to improve electromagnetic compatibility and protection against unauthorized correspondents. Diversity transmission method includes preset frequency setting for operation of radio line, in accordance with selected frequency pilot signal is generated, each antenna channel is assigned its antenna, forming a system of N antennae located on one line so that the distance between them is equal to half the wavelength defined by a given frequency, orienting the antenna system in the direction towards an illegitimate correspondent for antiphase reception.
EFFECT: technical result consists in reduction of level of information signal in direction to illegitimate correspondent due to orientation of antenna system, providing implementation of antiphase reception.
