Correct answer: antenna cable loss.
Why this is the answer
EIRP (Effective Isotropic Radiated Power) is a measure of the power radiated by an antenna in a specific direction. It's calculated by taking the transmitter's output power, adding the antenna's gain, and subtracting any losses in the cable connecting the transmitter to the antenna. Therefore, antenna cable loss is subtracted from the transmitter power (and then antenna gain is added) to arrive at the EIRP. Transmitter power is the starting point, not a parameter to subtract. Antenna gain is added, not subtracted. Signal-to-noise ratio (SNR) is a measure of signal quality, not a component of EIRP calculation.
