Height of antenna of transmitter and receiver is proportional to:

The physical sizes of the transmitter and receiver antenna in a communication system are:

(A) : Greater is the height of T.V. transmitting antenna, greater is its range. (R) : The range of T.V. transmitting antenna is proportional to square root of its height.

Greater the height of a T.V. transmitter antenna, greater is its coverage. Prove it.

The physical sizes of the transmitter and reciever antenna in a communication system are :

Draw the block diagram of working of a transmitter and a receiver.

If h_(T) and h_(R) are the height of the transmitting and receiving antennas above the earth's surface and R is the radius of earth, then distance between the transmitting and receiving antenna is
