It functions similarly to a searchlight or flashlight reflector to direct the radio waves in a narrow beam, or receive radio waves from one particular direction only. The main advantage of a parabolic antenna is that it has high directivity. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish.
