METHOD OF DECREASING LEVEL OF VOLTAGES INDUCED ON MATCHED LOADS OF COAXIAL CABLE BY NARROWBAND RADIO FREQUENCY INTERFERENCE

FIELD: radio engineering.SUBSTANCE: invention relates to electromagnetic compatibility of radioelectronic equipment, namely, to increasing resistance to external electromagnetic fields of connections made on the basis of a coaxial cable. Method of decreasing the level of voltages induced on matched loads of a coaxial cable by a narrowband radio frequency interference is based on formation of a single loop on the coaxial cable, thereby achieving misphasing of the interference inducing field and already induced voltage in the cable and involves determination of frequency f*, on which there is the minimum of the voltage induced at the ends of the coaxial cable when connecting to matched voltage loads as per the formula, where X is the length of the cable in meters, α is the wavelength shortening coefficient in the cable, c=3⋅10 m/sec is the speed of light in free space, it is compared with the known narrowband interference frequency f, if f
