A radio receiver operating at 477MHz with minimum sensitivity of -85dBm is connected to an antenna with gain +12dBi using a feeder cable with loss of -3dB.The transmitter is 40Km away and uses a parabolic antenna with gain of +23dBi. The transmitter feeds the antenna through a coaxial cable with -6dB loss. What is the minimum transmitter power required for reliable operation of the link assuming a fade margin of 10dB?
