A Radio Link Uses A Pair Of 2m Dish Antennas

A radio link uses a pair of 2m dish antennas with an efficiency of 60 percent each, as transmitting and receiving antennas. Other specifications of the link are:

Transmitted power = 1dBw

Carrier frequency = 4 GHz

Distance of the receiver from the transmitter = 150 in

Calculate

(a) The free-space loss,

(b) The power gain of each antenna, and

(c) The received power in dBW.
