A transmitter has an output power of 50 W. It is connected to its antenna by a feed line that is 25 m long and properly matched. The loss in the feedline is 5 dB/100m. The antenna has a gain of 8.5 dBi. a) How much power reaches the antenna? b) What is the EIRP in the direction of maximum antenna gain? c) What is the power density 1 km from the antenna, in the direction of maximum gain, assuming free-space propagation?
