## Answer Options

- **A)** Elevation
- **B)** Azimuth
- **C)** Near field
- **D)** Polarization

**Correct Answer: A**

## Explanation

Antenna radiation patterns are generally plotted in two orthogonal (perpendicular) planes to fully characterize the antenna’s radiation over a sphere. The two standard cuts are the horizontal plane and the vertical plane.

Figure E9-2 plots the antenna’s gain (in dBi) against the vertical angle from the horizon (or ground level, 0°) up to 90°. This graph shows how the signal radiates at different vertical angles. Therefore, Figure E9-2 shows an **Elevation** pattern (or vertical radiation pattern), which is critical for predicting HF skip propagation and VHF long-distance work.
