For low frequencies, it behaves similarly to a reflector dish, directing sounds toward the ear canal.
In this arrangement, two parabolic reflector dishes operate in a point to point microwave radio path (4 GHz to 85 GHz) with four radios, two mounted on each end.
The reflector dish of a huge lamp, unlit, hung above the equipment.
Network operators can opt to install reflector dishes or Stinger antennas or to use Canopy models that accept external antennas at one or both ends of the link to increase coverage distance.
DIRECTVs ultimate reflector dish used for home systems.
Malach's flesh turned white as the pressure-suit he was wearing, and his eyes widened into twin reflector dishes.
The block upconverter is a block shaped device assembled with the LNB in association with an OMT, orthogonal mode transducer to the feed-horn that faces the reflector parabolic dish.
The beam of radio waves from the feed illuminates the secondary reflector, which reflects it back to the main reflector dish, which reflects it forward again to form the desired beam.
The Arecibo Observatory houses the world's largest radio telescope, a beautiful structure (a work of art to many) featuring a huge, spherical reflector dish, 300m in diameter, composed of 40,000 perforated aluminium panels embedded into the surrounding jungle.
The small unmanned craft looked ungainly with its array of robotic arms, sensors, and reflector dishes.
