Ultra High Frequency
Ultra high frequency (UHF) is the ITU designation for radio frequency, radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter). Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by Line-of-sight propagation, line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for UHF television broadcasting, television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications.

Danville, Illinois
Danville is a city in and the county seat of Vermilion County, Illinois. As of the 2010 census, its population was 33,027. As of 2019, the population was an estimated 30,479. History The area that is now Danville was once home to the Miami, Kickapoo, and Potawatomi tribes of Native Americans. Danville was founded in 1827 on of land donated by Guy W. Smith and donated by Dan W. Beckwith. The sale of lots was set for April 10, 1827 and advertised in newspapers in Indianapolis, Indiana and the state capital of Vandalia. The first post office was established in May of the same year in the house of Amos Williams, organizer of Vermilion and Edgar Counties and a prominent Danville citizen. Williams and Beckwith drew up the first plat map; the city was named after Dan Beckwith at Williams' suggestion, although Beckwith suggested the names "Williamsburg" and "Williamstown". Beckwith was born in Pennsylvania in 1795 and moved to Indiana as a young man; in 1819 he accompanied the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microwave Transmission
Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300MHz to 300GHz(1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter, but such systems are expensive and generally used only in specialist roles. Although an experimental microwave telecommunication link across the English Channel was demonstrated in 1931, the development of radar in World War II provided the technology for practical exploitation of microwave communication. During the war, the British Army introduced the Wireless Set No. 10, which used microwave relays to multiplex eight telephone channels over long distances. A link across the English Channel allowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kinescope
Kinescope , shortened to kine , also known as telerecording in Britain, is a recording of a television program on motion picture film, directly through a lens focused on the screen of a video monitor. The process was pioneered during the 1940s for the preservation, re-broadcasting and sale of television programmes before the introduction of quadruplex videotape, which from 1956 eventually superseded the use of kinescopes for all of these purposes. Kinescopes were the only practical way to preserve live television broadcasts prior to videotape. Typically, the term Kinescope can refer to the process itself, the equipment used for the procedure (a movie camera mounted in front of a video monitor, and synchronized to the monitor's scanning rate), or a film made using the process. The term originally referred to the cathode ray tube used in television receivers, as named by inventor Vladimir K. Zworykin in 1929. Hence, the recordings were known in full as kinescope films or kines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Media Market
A media market, broadcast market, media region, designated market area (DMA), television market area, or simply market is a region where the population can receive the same (or similar) television and radio station offerings, and may also include other types of media such as newspapers and internet content. They can coincide or overlap with one or more metropolitan areas, though rural regions with few significant population centers can also be designated as markets. Conversely, very large metropolitan areas can sometimes be subdivided into multiple segments. Market regions may overlap, meaning that people residing on the edge of one media market may be able to receive content from other nearby markets. They are widely used in audience measurements, which are compiled in the United States by Nielsen Media Research. Nielsen measures both television and radio audiences since its acquisition of Arbitron, which was completed in September 2013. Markets are identified by the largest ...

Analog Television
Analog television is the original television technology that uses analog signals to transmit video and audio. In an analog television broadcast, the brightness, colors and sound are represented by amplitude, instantaneous phase and frequency, phase and frequency of an analog signal. Analog signals vary over a continuous range of possible values which means that Noise (electronics), electronic noise and interference may be introduced. Thus with analog, a moderately weak signal becomes Noise (video), snowy and subject to interference. In contrast, picture quality from a digital television (DTV) signal remains good until the signal level drops below digital cliff, a threshold where reception is no longer possible or becomes intermittent. Analog television may be wireless (terrestrial television and satellite television) or can be distributed over a cable network as cable television. All broadcast television systems used analog signals before the arrival of DTV. Motivated by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WAND And WBUI Towers
A wand is a thin, light-weight rod that is held with one hand, and is traditionally made of wood, but may also be made of other materials, such as metal or plastic. Long versions of wands are often styled in forms of staves or sceptres, which could have large ornamentation on the top. In modern times, wands are usually associated with stage magic or supernatural magic, but there have been other uses, all stemming from the original meaning as a synonym of rod and virge. A stick that is used for reaching, pointing, drawing in the dirt, and directing other people, is one of the earliest and simplest of tools. History It is possible that wands were used by pre-historic peoples. It is mentioned that 'rods' (as well as rings) were found with Red Lady of Paviland in Britain. It is mentioned by the author in ''Gower - A Guide to Ancient and Historic Monuments on the Gower Peninsula'' that these might have been wands and are depicted as such in a reconstruction drawing of the burial o ...
