Why a signal transmitted from a TV tower can't be received beyond a certain distance? write the expression for the optimum separation between the receiving and the transmitting antenna.
A signal transmitted from a TV tower can't be received beyond a certain distance, because of the curvature of the earth.
The radius of the earth be . the height of the transmitting antenna be
.then the optimum seperation
between the receiving and the transmitting antenna will be given as:-
