Electric Field Radiated by the RG-58 Coaxial Cable and Connectors Versus Cellflex Coaxial Cable and Connectors with Total Shielding

The main goal of this paper is to validate an experimental methodology and investigate the shield quality of RG-58 coaxial cables and connectors versus coaxial cable and connectors with total shielding for VHF/UHF band, from 100 MHz to 400 MHz. The experimental analysis reveals an important difference between the two sets of cables and connectors. A computational simulation was carried out with emphasis on validating the measurement of the resonance frequencies of the set used in the test. The electric field radiated by the RG-58 cable and connectors at 300 MHz, the ressonance frequency of the set, is 2.27 V/m. It can also be noticed that there is almost no electric field radiated by the CELLFLEX coaxial cable and connectors in this frequency, the level is 0,74 V/m which is close to the noise floor of the semi anechoic chamber.
