The skip-zone is defined as…

  • A

    the area, where only the ground wave is receivable.

  • B

    the area, where neither the ground waves nor the sky waves are received.

  • C

    the area, where ground and sky waves are receivable.

  • D

    the area, where only the sky wave is receivable.

Refer to figure.
A skip zone is a region where a radio transmission can not be received. Radio waves which travel near to the ground (groundwave) and towards the ionosphere (skywaves) have a skip zone. The skip zone is a region between the farthest point at which the groundwave can be received and the nearest point at which the refracted skywaves can be received.

The skip zone is a natural phenomenon that can never be influenced by technical means. It can only be reduced by decreasing the frequency of the radio waves. Reducing the frequency can be done by increasing the ionospheric width.
