A satellite transmitter, which is functioning at a frequency of 14 GHz and boasts an antenna gain of 55 dBi, is in operation. Situated at a distance of 25,000 kilometers from the transmitter, there is a receiver equipped with an antenna gain of 60 dBi. Given that the transmitter’s output power is 80 watts, one needs to determine the power delivered to the receiver.
