A.H. Systems Model EHA-51B Active Monopole and Loop Antenna
CALCULATIONS
EMISSIONS TESTING
Individual calibration data for the active loop antenna is supplied to comply
with various emissions test requirements. For emissions measurements, add
antenna factor plus cable loss to receiver reading in dBV to convert to field
strength in dBA/meter.
Field Strength(dBuA/m) = SA(dBuV) + MAF(dB/m) + cable loss (dB)
Fictitious electric field strength can be calculated by the following:

SA = Spectrum Analyzer or Receiver voltage reading
MAF = Magnetic Antenna Correction Factor
CL = Cable Loss in dB
dBV/m = dBA/m + 51.5
