Propagation Mode
-
The power transmitted from an antenna is spreaded ON a large area, along with the distance tge received power depends on wavelength and gain of transmitting antenna and receiving antenna but as soon as there is a matter between sender and receiver, the situation becomes More complex.There are three types of propagation modes transmitting the information from the air.
- Ground wave propagation (<2 MHz)
- Sky wave propagation (2 to 30 MHz)
- Line of sight propagation (> 30 MHz)
