Radio Wave Propagation Illustrated

The following illustrations show the characteristics of ground-wave and sky-wave

propagation during day and night time. In each illustration the height of the

ionosphere above the ground is shown.

In both illustrations Station A communicates with Stations B, C and D. Propagation

from Station A to B is by ground-wave. The diagrams illustrate that the ground

wave is not affected by the time of day and the height of the ionosphere above the

ground.

Propagation from Station A to C and D, however, is by sky-wave and as the

diagrams illustrate the sky wave is significantly affected by the time of day and the

height of the ionosphere above the ground.

Under each diagram there are recommended working frequencies listed. Please

note that these will vary according to time of year and other factors. They are

intended only as a guide and are subject to change.

Day

The sun is higher, the ionosphere is higher, the best frequency to use is

higher

A to B - Possible optimum working frequency is 3 MHz

A to C - Possible optimum working frequency is between 7

– 9 MHz

A to D - Possible optimum working frequency is between 13 - 16 MHz
