Abstract: Leaky coaxial cables are coaxial cables with gaps in their shielding, which allows the center conductor to radiate. We will use a new technique for HEMP shielding effectiveness testing in which the cables function as antennas, not transmission lines, replacing the conventional method in which the normal transmitting antennas, which are loops and bi-logical arrays. This report presents the calibration data for the leaky coaxial cable as a transmitting antenna for HEMP shielding effectiveness testing for both low frequency band from 10 KHz to 20 MHz, and high frequency band from 20 MHz to 1 GHz with different orientations.
