Question

Differentiate between space wave and sky wave propagation

Answer 1

Sky waves:

This works for high frequency radio waves between 2 – 30 MHz.

Sky Waves are reflected off the ionosphere

They are used for amateur radio and long distance aircraft and ship communication.

Space waves:

This is for very high frequency waves (30 – 300 MHz).

Space Waves only travel in straight lines (line of sight). They are used for mobile phones, two-way radio and radar.
