FIELD: physics, radio.
SUBSTANCE: invention refers to radio communications and aimed at backup for two and more (up to seven inclusive) single-object radio electronic facilities (REF) with crossed coverage paths and frequencies from working frequency range at uniform frequency spacing. Technical result is enabled by REF activation at frequencies (and appropriate channels), defined as provided various versions developed under formulas specified in method, which do not induce intermodulation products (IP) up to the seventh order inclusive both at transmission and receiving frequencies.
EFFECT: elimination of intermodulation products effect.
