Topeka
Topeka ( ; Kansa: ; iow, Dópikˀe, script=Latn or ) is the capital city of the U.S. state of Kansas and the seat of Shawnee County. It is along the Kansas River in the central part of Shawnee County, in northeast Kansas, in the Central United States. As of the 2020 census, the population of the city was 126,587. The Topeka metropolitan statistical area, which includes Shawnee, Jackson, Jefferson, Osage, and Wabaunsee Counties, had a population of 233,870 in the 2010 census. The name "Topeka" is a Kansa-Osage word that means "place where we dig potatoes", or "a good place to dig potatoes". As a placename, Topeka was first recorded in 1826 as the Kansa name for what is now called the Kansas River. Topeka's founders chose the name in 1855 because it "was novel, of Indian origin, and euphonious of sound."King, Dick (20 Nov. 2005)Topeka' rooted in spuds".

Kansas City, Missouri
Kansas City (abbreviated KC or KCMO) is the largest city in Missouri by population and area. As of the 2020 census, the city had a population of 508,090 in 2020, making it the 36th most-populous city in the United States. It is the central city of the Kansas City metropolitan area, which straddles the Missouri–Kansas state line and has a population of 2,392,035. Most of the city lies within Jackson County, with portions spilling into Clay, Cass, and Platte counties. Kansas City was founded in the 1830s as a port on the Missouri River at its confluence with the Kansas River coming in from the west. On June 1, 1850, the town of Kansas was incorporated; shortly after came the establishment of the Kansas Territory. Confusion between the two ensued, and the name Kansas City was assigned to distinguish them soon after. Sitting on Missouri's western boundary with Kansas, with Downtown near the confluence of the Kansas and Missouri Rivers, the city encompasses about , making ...

Ground Conductivity
Ground conductivity refers to the electrical conductivity of the subsurface of the earth. In the International System of Units (SI) it is measured in millisiemens per meter (mS/m). Radio propagation Ground conductivity is an extremely important factor in determining the field strength and propagation of surface wave (ground wave) radio transmissions. Low frequency (30–300 kHz) and medium frequency (300–3000 kHz) radio transmissions are particularly reliant on good ground conductivity as their primary propagation is by surface wave. It also affects the real world radiation pattern of high frequency (3-30 MHz) antennas, as the so called "takeoff angle" is not an inherent property of the antenna but a result of a ground reflection. For this reason ITU publishes an extensive world atlas of ground conductivities. Other uses Ground conductivity is sometimes used in determining the efficiency of a septic tank, using electromagnetic induction, so that contaminants ...

WBT (AM)
WBT (1110 kHz) is a commercial AM radio station serving the Charlotte metropolitan area, including parts of North Carolina and South Carolina. First licensed on March 18, 1922, it is one of America's first radio stations. The station airs a news/talk radio format simulcast on WBT-FM (99.3) and the HD2 digital subchannel of co-owned WLNK. WBT is owned by Urban One. Studios and offices are located off West Morehead Street, just west of Uptown Charlotte, co-located with the city's CBS television affiliate, WBTV, currently owned by Gray Television but at one time co-owned with WBT Radio. WBT broadcasts 50,000 watts around the clock as the only Class A clear-channel station in the Carolinas. Its transmitter is in the southern part of the city off Nations Ford Road. During daylight hours it uses a single non-directional antenna and is audible in much of the central Carolinas. At night it uses a directional antenna that limits its signal toward the west, in order to avoid interferi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Directional Antenna
A directional antenna or beam antenna is an antenna which radiates or receives greater power in specific directions allowing increased performance and reduced interference from unwanted sources. Directional antennas provide increased performance over dipole antennas—or omnidirectional antennas in general—when greater concentration of radiation in a certain direction is desired. A high-gain antenna (HGA) is a directional antenna with a focused, narrow radiowave beam width, permitting more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas are also in use all over Earth, most successfully in flat, open areas where there are no mountains to disrupt radiowaves. By contrast, a low-gain antenna (LGA) is an omnidirectional antenna with a broad radiowave beam width, that allows the signal to propagate reasonably well even in mountainous regions and is thus more reliable regardless of terrain. Low-gain antennas are often used in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tower Array
A tower array is an arrangement of multiple radio towers which are mast radiators in a phased array. They were originally developed as ground-based tracking radars. Tower arrays can consist of free-standing or guyed towers or a mix of them. Tower arrays are used to constitute a directional antenna of a mediumwave or longwave radio station. The number of towers in a tower array can vary. In many arrays all towers have the same height, but there are also arrays of towers of different height. The arrangement can vary. For directional antennas with fixed radiation pattern, linear arrangements are preferred, while for switchable directional patterns (usually for daytime groundwave versus nighttime skywave), square arrangements are chosen. Examples Tower arrays with guyed masts * Longwave transmitter Europe 1 * Transmitter Weisskirchen * Beidweiler Longwave Transmitter * Transmitter Wachenbrunn * Transmitter Ismaning (VoA-Station) Tower arrays with free standing towers * Junglinster L ...

Papillion, Nebraska
Papillion is a city in Sarpy County in the state of Nebraska, United States. Designated as the county seat, it developed as an 1870s railroad town and suburb of Omaha. The city is part of the larger five-county metro area of Omaha. Papillion's population was 24,159 at the 2020 census. Its growth since the late 20th century has reflected Omaha's. Overview The city was named after the creek of the same name which flows through its center; this had been named by early French explorers, as France had claimed this territory through the eighteenth century. The name Papillion is derived from the French term (''papillon'') for butterfly. According to local tradition, the early French explorers named the creek as ''Papillon'' because they saw so many butterflies along its grassy banks. The spelling was changed through a transliteration of the French word. Papillion was platted in 1870 when the railroad was extended to that point. Papillion (sometimes referred to as "Papio" by its resi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna (radio), antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for Communication engineering, communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
