FIELD: radio engineering.
SUBSTANCE: device for countering unauthorized transmission of control information by unauthorized devices contains a waveguide, an inductor as a source of electromagnetic pulses (EMP), a mechanical device for adjustable axial displacement of the inductor, a generator of short electrical pulses (EP), a control device. The waveguide is made in the form of a letter U.
EFFECT: increase in the probability of guaranteed radio suppression at the same energy density of the interference signal in the protected range, simplification of the device and increase in its reliability.
