WebJan 25, 2024 · 2. Sky Waves. The radio waves propagate from the transmitting antenna through the sky towards the receiver either directly or by reflection from the ground. Then, this kind of wave propagation is called skywave propagation. It is also called ionospheric wave propagation. It is used in short-wave broadcast services.
WebGenerally, the troposphere is extended up to 10 to 20 km above the surface of the earth. Thus space wave propagation occurs at about 20 km region in the atmospheric zone. … WebOccasionally, the first sky wave will return to Earth within the range of the ground wave. If the sky wave and ground wave are nearly of equal intensity, the sky wave alternately reinforces and cancels the ground wave, causing severe fading. This is caused by the phase difference between the two waves, a result of the longer path traveled by ...

It … WebThe MF range is from 300 to 3,000kHz. MF propagates by ground wave, direct wave, and sky wave. MF can span from 100 to 1,000 miles by ground wave and from 1,000 to 3,000 miles by sky wave, depending on the transmitter output power and the atmospheric conditions.
