cutoff frequency, design, etc should be added.

Anyone know the bandwidth, main beam width, gain and directivity? Do any operations / observations still take place using the antenna or is it a historical site?

Article Text Copied

The text in this article as of January 2006 was copied from this National Park Service web site. I assume the NPS website is not copyrighted, but the article should state its source.

Shouldn't this be an article on horn antennas in general and not the Holmdel horn antenna specifically?58.165.235.188 (talk) 08:54, 2 March 2008 (UTC)[reply]

Rename to Holmdel Horn Antenna or similar?

This article title is inappropriately generic. —Preceding unsigned comment added by 216.113.195.40 (talk) 09:16, 1 April 2008 (UTC)[reply]

I concur. I came here looking for details on horn antennas, not a particular notable example with no technical information. —Preceding unsigned comment added by Ktims (talk • contribs) 23:27, 21 March 2009 (UTC)[reply]

The Holmdel Horn Antenna is a large microwave horn antenna that was used as a satellite communication antenna and radio telescope during the 1960s at Bell Telephone Laboratories in Holmdel Township, New Jersey, United States. It was designated a National Historic Landmark in 1988 because of its association with the research work of two radio astronomers, Arno Penzias and Robert Wilson, who used it to discover the cosmic microwave background radiation (CMBR) that permeates the universe. This helped change the science of cosmology, the study of the history of the universe, from a field for unlimited theoretical speculation into a discipline of direct observation. In 1978, Penzias and Wilson received the Nobel Prize in Physics for their discovery.
