SUMMARY
The Effective Isotropic Radiated Power (EIRP) of an antenna is calculated using the formula EIRP = Power + Gain (in dBm). Given an EIRP of 60 dBm and an antenna gain of 30 dB, the input power to the antenna can be determined. The correct answer to the multiple-choice question is (b) 2W, as the input power can be derived from the relationship between EIRP, power, and gain.
