1.	Why a signal transmitted from a TV tower cannot received beyound a certain distance ? Write the expression for the optimum separation separation between the receiving and the transmitting antenna.
Answer» A signal transmitted from a TV tower cannot be received beyound a centarin distance due to attenuation and curvature of earth. Every antenna has the range. Rahge is the distance between a source and a destination up to which a signal is received with sufficient strength. Optimum distance between the receiving and transmitting antenna. `d_(M)=sqrt(2Rh_(T))+sqrt(2Rh_(R))` ` "where R = Radius of earth "` `h_(T)="Height of transmitting antenna"` `h_(R)="Height of receiving antenna"`
