Question

Difference between sky and space wave propagation

Answer 1

 waves have the ability topropagate through atmosphere, from transmitter antenna to receiver antenna. These waves can travel directly or can travel after reflecting from earth's surface to the troposphere surface of earth. ... Onlyspace wave propagation is left which can handle frequency waves of higher frequencies.

Answer 2

Distinguish between. Distinguish between "sky waves' and 'space waves' modes of propagation in communication system. ... Sky wave propagation takes place up to frequency of about 40 MHz. A space wave travels in a straight line from transmitting antenna to the receiving antenna.
