WXID-LP
WXID-LP, UHF analog channel 49, was a low-powered JCTV- affiliated television station licensed to Marietta, Georgia, United States. The station's transmitter was located atop Sweat Mountain, north-northwest of Atlanta. History Since being permitted in 1988, it was W55BM until March 2008, becoming W49DE after it was forced to change TV channels due to the DTV transition in the United States (which resulted in channel 55 being auctioned to MediaFLO). The station was previously owned by the Trinity Broadcasting Network, which sold it in 2010 to Word of God Fellowship, which changed the station to its current broadcast callsign in mid October 2010. Originally airing The Box, it later became a translator station for TBN-owned WHSG-TV. The station later affiliated with the TBN-owned JCTV network, making it one of the few TBN-owned analog stations to carry programming other than TBN. This programming was also seen on one of WHSG's digital subchannels: virtual channel 63.3, via ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WHSG-TV
WHSG-TV (channel 63) is a religious television station licensed to Monroe, Georgia, United States, serving the Atlanta area as an owned-and-operated station of the Trinity Broadcasting Network (TBN). The station's studios are located on Agape Way in Decatur, and its transmitter is located in Atlanta's Cabbagetown section. Because it airs no local content (except for local insertion of the required station identification), it is not carried as a local channel on DirecTV; the network's national feed is already available, but TBN's subchannel sister networks are not available. It had one broadcast translator, W55BM, licensed to Marietta with transmitter atop Sweat Mountain, northwest of Atlanta. That station was later W49DE and WXID-LP, an affiliate of JCTV. History The station launched on March 15, 1991. As the call sign indicates, it initially served as an affiliate of the Home Shopping Network, replacing WNGM (now WUVG-DT). Later, TBN bought the station and changed to the cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweat Mountain
Sweat Mountain is a mountain in far northeastern Cobb County, Georgia, in the suburbs north of Atlanta. The exact GNIS location of its summit is , and it has an official (USGS) elevation of above mean sea level. It is the second-highest point in the county behind Kennesaw Mountain, and second in the core metro Atlanta area, behind Kennesaw Mountain, which is also in Cobb County. It is fifth if the exurban counties further north are considered. This height has made the mountain very attractive for radio, having several transmitters, radio towers, and antennas, for pagers, cellphones, broadcasting, and amateur radio. The fact that Stone Mountain and Kennesaw Mountain are both protected as parks has led to a proliferation of technology at the top. At the same time, both the antenna farm and the densely packed houses detract from the view of the mountain from surrounding areas of northeast Cobb, south-southeast Cherokee (including much of Woodstock), and western Roswell.

Ultra-high Frequency
Ultra high frequency (UHF) is the ITU designation for 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; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for 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. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE radar bands ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DTV Transition In The United States
The digital transition in the United States was the switchover from analog to exclusively digital broadcasting of terrestrial television programming. According to David Rehr, then president and CEO of the National Association of Broadcasters, this transition represented "the most significant advancement of television technology since color TV was introduced." For full-power TV stations, the transition went into effect on June 12, 2009, with stations ending regular programming on their analog signals no later than 11:59 p.m. local time that day. Under the Digital Transition and Public Safety Act of 2005, full-power broadcasting of analog television in the United States was initially planned to have ceased after February 17, 2009. To help U.S. consumers through the conversion, the Act also established a federally sponsored DTV Converter Box Coupon Program. The DTV Delay Act changed the mandatory analog cutoff date to June 12, 2009, although stations were permitted to cease ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlanta Metropolitan Area
Metro Atlanta, designated by the United States Office of Management and Budget as the Atlanta–Sandy Springs–Alpharetta, GA Metropolitan Statistical Area, is the most populous metropolitan statistical area in the U.S. state of Georgia and the eighth-largest in the United States. Its economic, cultural and demographic center is Atlanta, and its total population was 6,144,050 according to the 2021 estimate from the U.S. Census Bureau. The metro area forms the core of a broader trading area, the Atlanta–Athens-Clarke–Sandy Springs Combined Statistical Area. The Combined Statistical Area spans up to 39 counties in north Georgia, and one county in Alabama, Chambers. The Combined Statistical Area recorded in the 2020 census a population of 6,930,423. Atlanta is the second-largest metropolitan area in the Census Bureau's Southeast region, behind that of Greater Washington, D.C. It surpassed the Greater Miami area in total population in 2021.

Sandy Springs
Sandy Springs is a city in northern Fulton County, Georgia and an inner ring suburb of Atlanta. The city's population was 108,080 at the 2020 census, making it Georgia's seventh-largest city. It is the site of several corporate headquarters, including UPS, Newell Brands, Inspire Brands, Focus Brands, Cox Enterprises, and Mercedes-Benz USA's corporate offices. History Human settlement in the area can be traced back to approximately 400 CE, when Native Americans forged three trails to better access the area's freshwater springs. In the 16th century, the Creek Muskogee tribe settled the area, where they remained until the early 1800s, when they were forced out of the area due to the discovery of gold. In 1821, the federal government held a number of land lotteries in the area, resulting in the purchase of land in present-day Sandy Springs and its subsequent settlement. The Austin-Johnson House, the oldest existing unaltered house, was built in 1842 on what is now Johnson Ferr ... [...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] |
Dark (broadcasting)
In the broadcasting industry, a dark television station or silent radio station is one that has gone off the air for an indefinite period of time. Usually unlike dead air (broadcasting only silence), a station that is dark or silent does not even transmit a carrier signal. U.S. law Transmitter operations According to the U.S. Federal Communications Commission (FCC), a radio or television station is considered to have gone dark or silent if it is to be off the air for thirty days or longer. Prior to the Telecommunications Act of 1996, a "dark" station was required to surrender its broadcast license to the FCC, leaving it vulnerable to another party applying for it while its current owner was making efforts to get it back on the air. Following the 1996 landmark legislation, a licensee is no longer required to surrender the license while dark. Instead, the licensee may apply for a "Notification of Suspension of Operations/Request for Silent STA" (FCC Form 0386), stating the reas ...

Omnidirectional Antenna
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis. When graphed in three dimensions ''(see graph)'' this radiation pattern is often described as ''doughnut-shaped''. Note that this is different from an isotropic antenna, which radiates equal power in ''all'' directions, having a ''spherical'' radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie ...

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Channel
In most telecommunications organizations, a virtual channel is a method of remapping the ''program number'' as used in H.222 Program Association Tables and Program Mapping Tables to a channel number that can be entered via digits on a receiver's remote control. Often, "virtual channels" are implemented in digital television, helping users to find a desired channel easily, or easing the transition from analogue to digital broadcasting in general. The practice of assigning virtual channels is most common in those parts of the world where TV stations were colloquially named after the RF channel they were transmitting on ("Channel 6 Springfield"), as it was common in North America during the analogue TV era. In other parts of the world, such as Europe, virtual channels are rarely used or needed, as TV stations there identify themselves by name, not by RF channel or callsign. A "virtual channel" was first used for DigiCipher 2 in North America. It was later used and referred to as a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Subchannel
In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting". ATSC television United States The ATSC digital television standard used in the United States supports multiple program streams over-the-air, allowing television stations to transmit one or more subchannels over a single digital signal. A virtual channel numbering scheme distinguishes broadcast subchannels by appending the television channel number with a period digit (".xx"). Simultaneously, the suffix indicates that a television station offers additional programming streams. By convention, the suffix position ".1" is normally used to refer to the station's main digi ...
