Horn Antenna

Also known as: Horn Reflector Antenna
Off Garden State Parkway in Crawford Hill Facility, Holmdel, New Jersey



The Horn Antenna, at the Bell Telephone Laboratories, is associated with the research work of two radio astronomers, Dr. Arno A. Penzias and Dr. Robert A. Wilson. In 1965, while using the Horn Antenna, Penzias and Wilson stumbled on the microwave background radiation that permeates the universe. This discovery--the most important in modern astronomy since Edwin Hubble demonstrated in the 1920s that the universe was expanding--provided evidence that confirmed the "Big Bang" theory of the creation of the universe. In 1978 Penzias and Wilson received the Nobel Prize for Physics. -- National Historic Landmark statement of significance, December 20, 1989
