Large loop antenna 9KHz–30MHz

A large loop antenna with three orthogonal loops as required by ISPR16-1-4 and CISPR 15 / EN 55015.

It is used to measure the current induced by the magnetic field emitted from the lighting fixture. Section 4.4 of EN 55015 specifies the test setup and measurement procedures. It consists of three vertical 2-meter diameter loop antennas on three orthogonal planes (X/Y/Z), installed on a lightweight hollow WPC frame with a total height of 2.5 meters. The lowest point of the loops is 0.5 meters above the ground, and each loop element receives magnetic field radiation that is perpendicular to the accommodating plane, generating a voltage signal at the output port of the RF transducer connected to the loop, proportional to the intensity of the H-field radiation. It is equipped with three TekBox TBCCP1-2K70 coaxial RF current monitoring probes with a flat transfer impedance of 0 dBΩ (1V/A) from 9 kHz to 30 MHz at a 50Ω load. The kit includes all necessary coaxial cables, ferrite clamps, a manual RF coaxial switch for selecting loops, and a TBTP3 tripod with a plastic DUT support plate.
