Which of the following improves the efficiency of a ground-mounted quarter-wave vertical antenna?
Pick an answer to check it.
Answer: A. Installing a ground radial system
A ground-mounted vertical loses power in the soil. A system of ground radials gives a low-loss return path and improves efficiency.
Tip: More radials, less ground loss.
