Electrical Field Strength Conversion Table

In the far field, Zo = 120π (377Ω)

                                 Field Strength Calculation:
The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain from the measured reading. The basic equation is as follows:

FS = RA + AF + CF - AG
Where:
FS = Field Strength
RA = Receiver Amplitude
AF = Antenna Factor
CF = Cable Attenuation Factor
AG = Amplifier Gain

1 Gauss = 100 microTesla = 80 Amps/meter
