A transmitter has a power output of 10W at a carrier frequency of 250 MHz. It is connected by 10 m of a transmission line having a loss of 3 dB/100m to an antenna with a gain of 6 dBi. The receiving antenna is 20 km away and has a gain of 4 dBi. There is negligible loss in the receiver feedline, but the receiver is mismatched; the antenna and line are designed for a 50-2 impedance, but the receiver input is 75-2. assuming free-space propagation. А. Calculate the power delivered to the receiver, 204 nW В. 2040 nW С. 2.04 nW D. 20.4 nW
