### Explanation of question 16

In Fig. 21.5, distance a represents the limit of a ground wave and distance (b - a) the skip distance. The shaded area will be the

1. high-signal zone
2. radio zone
3. skip zone
4. ground zone

The answer is :- 3 Questions 15 (previous) and 16 are effectively the same problem. If a vertical antenna radiates in all directions around itself, there will be a ‘dead area’ or skip zone.
