A 37.4W transmitter at 86.7 MHz will be used to establish VHF communication. Determine the maximum distance at which LOS communication is possible if the transmitting and receiving antennas are 51.2 and 24.68 meters tall, respectively. Determine the receiving point's field strength. Earth's radius is 6353 kilometres.
The transmitter and receiver antennas used in a long range microwave communication system operating at 9 GHz are identical and separated by 10km from each other. The receiver power must be at least 10*10-6 W to meet the receiver's signal to noise ratio. Assuming that both antennas are aligned for maximum reception and are polarization compatible, what should be the gain of the transmit and receive antennas in dB when the input power of the transmitter antenna is 10W
