Microwaves Link à Microwaves  are the E. M. Waves of ν = 1GHz to 3 GHz. This is the ν more than that of T.V. signals . These waves have good directional properties due to which tey can be directed as abeam in a particular direction .Thesse waves do not bend arund the corners of the obstacle . The microwave link  on the surface of earth is possible if transmitting and receiving antenna are in line of sight so microwave propagation is also known as  Line of Sight Propagation.  The range of Microwave propagation is limited due to …

1. Curvature of Earth
2. High Frequency

The range of microwave propagation can be increased by using repeaters.
