WXBN (AM)
WXBN (880 kHz) is a commercial AM radio station licensed to Sweetwater, Florida, and serving the Miami–Fort Lauderdale radio market. It is owned by iHeartMedia, Inc., and airs a black-oriented news format as an affiliate of the co-owned Black Information Network. 880 AM is a United States clear-channel frequency reserved for Class A WCBS in New York City. WXBN uses a highly directional antenna array (8 towers) to prevent interference to WCBS's nighttime skywave signal. The transmitter is off the Tamiami Trail ( U.S. Route 41) in Everglades, Florida. History Florida City Radio A construction permit was granted to Florida City Radio by the Federal Communications Commission (FCC) on February 18, 2008, to start this station. The call letters WZAB were issued on July 15, 2008. But the station did not go on the air until Salem Communications began its local marketing agreement (LMA) with Florida City Radio to operate the station. WZAB made its debut on October 7, 2008, ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweetwater, Miami-Dade County, Florida
Sweetwater is a city in Miami-Dade County, Florida, United States. As of the 2020 census, the population was 19,363, up from 13,499 in 2010. Geography Sweetwater is located west of downtown Miami at (25.765977, –80.373624). It is bordered to the north and northeast by the city of Doral, to the southeast by Fontainebleau, to the south by Westchester, and to the west by Tamiami. The Ronald Reagan Turnpike forms the western edge of the city, and the Dolphin East-West Expressway crosses the center. U.S. Route 41 (Southwest 8th Street) follows the city's southern border. According to the United States Census Bureau, Sweetwater has a total area of , of which are land and , or 9.58%, are water. The city tripled in size in 2010 upon the annexation of additional areas, including where Dolphin Mall is located. The annexed area is roughly bounded by Northwest Seventh and 25th streets, 107th Avenue and Florida's Turnpike extension. The city on December 1, 2021, received approval ...

City Of License
In American, Canadian, and Mexican broadcasting, a city of license or community of license is the community that a radio station or television station is officially licensed to serve by that country's broadcast regulator. In North American broadcast law, the concept of ''community of license'' dates to the early days of AM radio broadcasting. The requirement that a broadcasting station operate a ''main studio'' within a prescribed distance of the community which the station is licensed to serve appears in U.S. law as early as 1939. Various specific obligations have been applied to broadcasters by governments to fulfill public policy objectives of broadcast localism, both in radio and later also in television, based on the legislative presumption that a broadcaster fills a similar role to that held by community newspaper publishers. United States In the United States, the Communications Act of 1934 requires that "the Commission shall make such distribution of licenses, fr ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the 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, such as radio and television broadcasting stations, cell phones, walkie-talkies, 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 purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmi ...

Skywave
In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Since it is not limited by the curvature of the Earth, skywave propagation can be used to communicate beyond the horizon, at intercontinental distances. It is mostly used in the shortwave frequency bands. As a result of skywave propagation, a signal from a distant AM broadcasting station, a shortwave station, or – during sporadic E propagation conditions (principally during the summer months in both hemispheres) a distant VHF FM or TV station – can sometimes be received as clearly as local stations. Most long-distance shortwave ( high frequency) radio communication – between 3 and 30 MHz – is a result of skywave propagation. Since the early 1920s amateur radio operators (or "hams"), limited to lower transmitter power than broadcast stations, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antenna Array
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called ''elements'') are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. The radio waves radiated by each individual antenna combine and superpose, adding together ( interfering constructively) to enhance the power radiated in desired directions, and cancelling ( interfering destructively) to reduce the power radiated in other directions. Similarly, when used for receiving, the separate radio frequency currents from the individual antennas combine in the receiver with the correct phase relationship to enhance signals received from the desired directions and cancel signals from undesired directions. More sophisticated array antennas may have multiple transmitter or receiver modules, each connected to a separate ... [...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.
