Re: [PSES] Small loop antenna

2020-07-13 Thread Ken Javor 
You didn¹t cite frequency range specifically and I¹m not familiar with
frequency range of the specificaiton citation.  A standard for 30 Hz to 100
kHz is a 13.3 cm diameter model with 36 turns of wire.  Developed iaw
MIL-STD-462. Another covering the same range developed later for the same
spec is even smaller in diameter.  As John Woodgate noted, there are some
magnetic field probes made by ETS Lindgren and others developed as
troubleshooting probes.  These have various smaller diameters and varying
number of turns, and the calibration factor is simply calculated based on
the area and number of turns (Faraday Law calculation).

Does anyone know of a commercially-available small loop antenna (4.3.2 of
CISPR 16-1-4) that isn't a 60 cm diameter circle?
