Dear Aaronia team
I found this in the documentation

Conversion factor: 1 (0 dB A/m is 0dBm)
Impedance: 50 Ohm

But, my spectrum analyzer need a Factor in dB (dB/Ωm) In order to read Volt from a value of field in dB(A/m)
Could you please provide me this value or the equation to get it ?

Thats simple:

MAGNETIC field:
dBµA/m = dBµV + AF
ELECTRIC field:
dBµV/m = dBµA/m + 51,5 (But please note that the MDF antennas have a large E-Field supression of about 25 to 50dB, see data sheet to get the values at a specific frequency)

Snip
