A communication system has two identical antennas operated at 6 GHz and aligned for maximum reception to each other. To allow the receiver antenna to detect the transmitted signal of 25 W over a distance of 40 km, the receivied signal power must be greater than or equal to -25 dBm. Calculate the required receiving antenna gain to detect the signal efficintly.
