Definition of sky wave in English: sky wavenoun A radio wave reflected from the ionosphere. Example sentencesExamples - Regional over the horizon communications are possible through a sky wave technique called tropospheric scatter (troposcatter or just tropo).
- It should be mentioned that neither surface waves nor sky waves are possible in space or on airless bodies such as the Moon.
- The ground wave is much stronger than the sky wave so softer wave pockets can be found at the closer distances.
- The AS2259, near vertical incident sky wave, worked sometimes, but a doublet antenna 10 feet off the ground nearly always worked.
- These radio signals are termed sky waves for obvious reason.
- At intermediate ranges, the sky wave will be coming in at an appreciable angle and it will be less effected by mountains.
- As well as the ground wave, which propagates at all times, at night a sky wave is also propagated via the ionosphere.
- Note that some absorption of sky waves may also occur at lower atmospheric levels because of the presence of water and water vapor.
- HF has excellent sky wave and good surface wave performance and is good for long range communications, though it is subject to interference.
- Fading can also occur on long circuits when sky wave signals take multiple hops to reach the receiver.
- Which of the following layers of the Ionosphere has no effect on sky wave propagation during the hours of darkness?
- The most important factor that effects the propagation of sky waves is the ionosphere.
- Using sky waves it is thus impossible to work on frequencies too away below or above the MUF.
