Find out the field strength at 1 on away from an isotopic station of 1 kW power.

Expert Solution
Step 1

Unlike directive transmitting stations which transmit in a specific direction, an isotropic station radiates equally in all directions. The electric field strength (rms value) at a distant point from the isotropic station is given by

узОР
E,
V/m –--> (1)
rms
P, = Transmitted power by the isotropic station
r = Distance of the distant point from the station
Step 2

In this case, the values of the power transmitted by the isotropic antenna and the distance of the distant point from the station are given as

P, = 1 kW = 1000 W
r =1 km = 1000 m
