6. A 10-GHz line-of-sight microwave communication link consists of two lossless parabolic dish antennas, each has 40 dB gain. If the receiver antenna requires 3 nW of receive power for good reception and the distance between the antennas is 35 km, how much power (in both mW and dBm) should be transmitted?

Two radio antennas separated by d = 294 m as shown in the figure below simultaneously broadcast identical signals at the same wavelength. A car travels due north along a straight line at position x = 1090 m from the center point between the antennas, and its radio receives the signals. Note: Do not use the small-angle approximation in this problem. (a) If the car is at the position of the second maximum after that at point O when it...
