Encyclopedia > Zone of Silence

In telecommunication, a skip zone is an annular region within the transmission range of an antenna, within which signals from the transmitter are not received.


The skip zone is bounded by the locus of the farthest points at which the ground wave can be received and the nearest points at which reflected sky waves can be received. Snyonyms for the skip zone include the silent zone and the zone of silence.

Skip zone - Wikipedia, the free encyclopedia (268 words)
When using medium to high frequency radio telecommunication, there are radio waves which travel both parallel to the ground, and towards the ionosphere, referred to as a ground wave and sky wave, respectively.
A skip zone is an annular region between the furthest points at which the ground wave can be received and the nearest point at which the refracted sky waves can be received.
The skip zone can be diminished by increasing the number of directions in which the skywave is transmitted or by decreasing the refractive angle of the skywave.
