HF RADIO TRANSMISSION

ENVOY™ TRANSCEIVER REFERENCE MANUAL 427

Sky wave

The sky wave is the most important form of HF propagation. The HF radio wave is

transmitted toward the sky and is reflected by the ionosphere to a distant receiver on

earth.

The reflective properties of the ionosphere change throughout the day, from season to

season, and yearly.
