SIMULATION OF ELECTROMAGNETIC PICKUP ON CCTV COAXIAL CABLE

Abstract

The utilization of computer-aided design FEKO for simulation of electromagnetic interference on coaxial cables of different types, such as those used in CCTV (RG59/U, RG11/U, RG179/U) is proposed. Item and parameters selection for this simulation rationale is given. The obtained results are described and analyzed. It was found that a cable RG179U is the most vulnerable to external electromagnetic radiation among of all coaxial cables used in the CCTV design. It was revealed that the electromagnetic interference levels on coaxial cable depends on this one length and takes maximum value when it is a multiple of the external electromagnetic radiation wavelength. A method for electromagnetic interference on the cable network CCTV reduction is proposed.
