The height of antenna used in communication is

The sum of the heights of transmitting and receiving antenae in the sight of communication is h. Prove that the range is maximum if the two antennae have a height of h/2 each.

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

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

Modulation helps to reduce the antenna size in wireless communication-Explain.

If the sum of the heights of transmitting and receiving antennae in line of sight of communication is fixed at h , the range is maximum when the two antennae have a height
