Summary
The 15 meter <a href="https://en.wikipedia.org/wiki/Holmdel_horn_antenna" class="extiw" title="wikipedia:Holmdel horn antenna">Holmdel horn antenna</a> at Bell Telephone Laboratories in Holmdel, New Jersey was built in 1959 for pioneering work in communication satellites for the NASA ECHO I. The antenna was 50 feet in length and the entire structure weighed about 18 tons. It was comprised of aluminum with a steel base. It was used to detect radio waves that bounced off Project ECHO balloon satellites. The horn was later modified to work with the Telstar Communication Satellite frequencies as a receiver for broadcast signals from the satellite. In 1964, radio astronomers <a href="https://en.wikipedia.org/wiki/Robert_Woodrow_Wilson" class="extiw" title="wikipedia:Robert Woodrow Wilson">Robert Wilson</a> and <a href="https://en.wikipedia.org/wiki/Arno_Penzias" class="extiw" title="wikipedia:Arno Penzias">Arno Penzias</a> discovered the <a href="https://en.wikipedia.org/wiki/cosmic_microwave_background_radiation" class="extiw" title="wikipedia:cosmic microwave background radiation">cosmic microwave background radiation</a> with it, for which they were awarded the 1978 Nobel prize in physics. In 1990 the horn was dedicated to the National Park Service as a National Historic Landmark.
