Emissions attenuated more than 20 dB below the permissible value are not reported. 2. The field strength is calculated by adding the antenna factor, high pass filter loss(if used) and cable loss, and subtracting the amplifier gain(if any)from the measured reading. The basic equation calculation is as follows: Result = Reading + Corrected Factor Where Corrected Factor = Antenna Factor + Cable Loss + High Pass Filter Loss – Amplifier Gain 3.
