I think we may be assuming this overload is caused by the EUT. But this is just as likely to be caused by something else. Medium Wave and Long Wave broadcasting produces powerful fields at some distance from an antenna. This has a fix.
If you place a narrowly resonant loop antenna, with feed point shorted, in close proximity to the wideband loop used for measurements, it will reduce pickup at the resonant frequency to a small fraction of the normal amount, and you will be able to at least SEE signals front-end overload may have prevented you from being able to notice. At frequencies far from the secondary loop's resonance, the measuring loop antenna factor will not be much affected, and you will even be able to get a useful idea of the fields you are seeing from the EUT. If you wish, you can have your loop recalibrated with the resonant loop permanently attached, which will restore the ability to make acceptable measurements.
