A bowl-shaped antenna that reflects and focuses incoming radio waves into a narrow beam directed toward a receiver typically positioned above the center of the unit. Also called a "dish" or "mirror," parabolic antennas are used for satellite signals and planetary telescopes. The reflective mirror design can also emit energy such as in a flashlight or automobile headlight. See DBS.
