Parabolic reflector - Wikipedia
A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis.

Parabolic antenna - Wikipedia
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity.
What is a Parabolic Dish? - Spiegato
A parabolic dish is a reflective instrument with a circular, parabolic shape that can collect or project different types of energy. Using the geometric principles of the parabola, the dish can efficiently both receive and reflect energy from distant sources.

The Parabolic Reflector Antenna (Satellite Dish) - Antenna Theory
The most well-known reflector antenna is the parabolic reflector antenna, commonly known as a satellite dish antenna. Examples of this dish antenna are shown in the following Figures. Figure 1. The "big dish" antenna of Stanford University. Figure 2. A random direcTV dish antenna on a roof.
PARABOLIC DISH ANTENNAS Paul Wade N1BWT © 1994,1998 Introduction Parabolic dish antennas can provide extremely high gains at microwave frequencies. A 2-foot dish at 10 GHz can provide more than 30 dB of gain. The gain is only limited by the size of the parabolic reflector; a number of hams have dishes larger than 20 feet, and
