Which type of antenna is typically used for Height Finding (HF)?

The orange peel antenna is specifically designed for height-finding radar systems, making it the correct choice in this context. This type of antenna is characterized by its unique structure, which resembles the surface of an orange peel. It is particularly effective for tracking and determining the altitude of aerial targets due to its capability to provide a wide field of view and offer good accuracy in angle of arrival measurements.

While various types of antennas like the paraboloid, horizontally truncated paraboloid, and other paraboloid structures may be used in different applications such as satellite communication or general radar, the orange peel design is specifically tailored for the height-finding purpose, providing the necessary gain and directional characteristics required for reliable performance in this specific task.
