Basic Radio & Television, 2/E
Such a zone or belt is called the skip zone (Fig. 12.3). Skip distance depends on
the frequency of the waves, the time of the day and the angle at which the wave
enters the ionosphere. In order to keep the skip distance same for a particular ...

The Electronics Handbook, Second Edition
Multiple hops are possible as the wave is reflected from the Earth back up to the
ionosphere for another pass. The area beyond the usable range of the
groundwave and the point of return to Earth of the skywave is known as the skip
zone as ...

Between each surface skip zone and the next overlap zone the apparent velocity
would be the porous refractor velocity of 1 9 960 or 1 8 270 ft/s (6083 or 5569 m/s
) for refractor porosity increases of three per cent and six per cent respectively.
