Briefly explain space wave propagation.

Explanation

When the radiowaves from the transmitting antenna reach the receiving antenna either directly or after reflection from the ground or in troposphere, the wave propagation is called space wave propagation. In space wave propagation, the reception is possible only if the receiving antenna directly intercept the message signal, as the space waves travels in straight line from transmitting antenna to the receiving antenna. Therefore, the space waves are used for the line of sight communication rude as microwave link, satellite communication and television broadcast.
