FIELD: protection of goods. SUBSTANCE: signalling element is part of signalling system; it is used to receive variable magnetic field at frequency F radiated by transmitter; proposed element may be used for reradiation of variable magnetic field with no addition of energy; this reradiation is received and detected by receiver. Signalling element has circuit including coil, capacitive diode and resistor connected in series in closed circuit and capacitor connected in parallel with resistor; coil and diode capacitor form resonance circuit possessing resonance at frequency F when voltage at diode is equal to zero. EFFECT: simplified construction; economical efficiency; easy detection and avoidance of false operation. 8 cl, 4 dwg
