Question

Why a signal transmitted from a TV tower cannot be received beyond a certain distance? Write the expression for the optimum separation between the receiving and the transmitting antenna.​

Answer 1

Explanation:

♥ The signal transmitted from a TV tower cannot be received beyond a certain distance because the surface of the earth is curved like sphere

♥ Expression for optimum separation between receiving and transmitting antenna is

d = √2hR

where

d = optimum separation

h = height of the antenna

R = Radius of curvature of earth

hope it helps u......❣️

Answer 2

The curvature of the earth limits the distance up to which a signal can be transmitted by a tower.

If the height of the transmitting antenna is h

and the radius of the earth is R

,then the optimum distance D

between the receiving and the transmitting antenna is given by:

D =√2Rh
