(c) A TV broadcast antenna transmits power of 3 kW at frequency of 200 MHz. The transmitter antenna has pattern solid angle of 1.3 sr, radiation resistance R = 45 W and dissipative resistance R 15 W. A home television antenna with a gain of 25 dB and pattern solid angle of 1.5 sr is located at a distance of 60 km from the TV broadcast transmitter. Calculate the following antennas fundamental parameters: (i) The transmitter antenna directivity. (ii) The transmitter antenna efficiency and maximum gain. (iii) The receiver antenna effective area. (iv) The power received at the home television antenna.
