Communications Hill
Communications Hill is a neighborhood located in the San Juan Bautista Hills of San Jose, California. History Before the Spanish entrada, the Tamyen people mined the area for chert, which was typically used for debitage and arrow points. On November 29, 1777, Juan Bautista de Anza selected the area to become the southernmost region in the first land tract of the San Jose pueblo (the first pueblo-town in California not associated with a mission or a military post). Although similarly named, the San Juan Bautista Hills were not part of the neighboring Rancho San Juan Bautista Mexican land grant. Located in the northern area of Communications Hill, Oak Hill Memorial Park, the oldest secular cemetery operating in California, performed its first recorded burial in 1847. Tyler Beach purchased the Dairy Hill area in the late 1860s and named it Beach Hill Farm, which was used to supply the former St. James Hotel. On March 2, 1886, Southern Pacific incorporated the San Jose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horn Antenna
A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horns are widely used as antennas at UHF and microwave frequencies, above 300 MHz. They are used as feed antennas (called feed horns) for larger antenna structures such as parabolic antennas, as standard calibration antennas to measure the gain of other antennas, and as directive antennas for such devices as radar guns, automatic door openers, and microwave radiometers. Their advantages are moderate directivity, low standing wave ratio (SWR), broad bandwidth, and simple construction and adjustment. One of the first horn antennas was constructed in 1897 by Bengali-Indian radio researcher Jagadish Chandra Bose in his pioneering experiments with microwaves. reprinted in The modern horn antenna was invented independently in 1938 by Wilmer Barrow and G. C. Southworth The development of radar in World War 2 stimulated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AT&T Long Lines
AT&T Communications, Inc., was a division of the AT&T Corporation that, through 23 subsidiaries, provided interexchange carrier and long-distance telephone services. History AT&T Long Lines The American Telephone & Telegraph Long Lines wire, cable, and microwave radio relay network provided long-distance services to AT&T and its customers. The connection to other countries from the United States began here. By the 1970s, 95% of distance and 70% of intercity telephone calls in the United States were carried by AT&T. Before utilizing microwave relay and coaxial cables, AT&T used lines for long-distance service. In 1911, the system connected New York to Denver. The introduction of repeater towers allowed such connections to reach across North America. In the 1930s the company experimented with long-distance coaxial cable. The first long-distance L-carrier coaxial link in 1936 connected Philadelphia and New York City. With improved klystrons and other microwave devices d ...
