In addition, I seem to recall that the primary coupling into a system under test below 80 MHz was determined to be cables in that system due to the wavelength below 80 MHz That threat would then be covered by the RF Common Mode tests in 61000-4-6 at freqs below 80 MHz [freq range / level depends upon Product Standard]. These tests use capacitive clamps / CDNs / etc to coupling interferes onto the system cables. Has been awhile since I did any of that testing though! Best regards, Mac Elliott

Consider both antenna and absorber performance in this frequency range, and at higher field intensities, required amplifier power.
