Earths Surface Earths Atmosphere

Once radio-frequency energy has been emitted from an antenna it will travel away from the antenna, where it is generated from, at the speed of light. Once it is sent the wave exists and propagates independently of the system that produces it. This means that changes, which occur at the transmitter (antenna), wil...
