picture info	Effective Radiated Power 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 in watts per square meter) as the actual source 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 [...More...]
	Sister Station In broadcasting, sister stations or sister channels are radio or television stations operated by the same company, by direct ownership or through a management agreement. Radio sister stations will often have different formats, and often one station is on the AM band while another is on the FM band. Conversely, several types of sister-station relationships exist in television; stations in the same city will usually be affiliated with different television networks (often one with a major network and the other with a secondary network), and may occasionally shift television programs between each other when local events require one station to interrupt its network feed. Sister stations in separate (but often nearby) cities owned by the same company may or may not share a network affiliation. For example, WNYW WNYW and WWOR-TV, in New York City New York City and Secaucus, New Jersey, are both owned by 21st Century Fox [...More...]

picture info	Hertz The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units International System of Units (SI) and is defined as one cycle per second.[1] It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz Hertz are commonly expressed in multiples: kilohertz (103 Hz, kHz), megahertz (106 Hz, MHz), gigahertz (109 Hz, GHz), and terahertz (1012 Hz, THz). Some of the unit's most common uses are in the description of sine waves and musical tones, particularly those used in radio- and audio-related applications [...More...]
picture info	Radio Station A radio station is a set of equipment necessary to carry on communication via radio waves. Generally, it is a receiver or transmitter, an antenna, and some smaller additional equipment necessary to operate them. Radio stations Radio stations play a vital role in communication technology as they are heavily relied on to transfer data and information across the world.[1] More broadly, the definition of a radio station includes the aforementioned equipment and a building in which it is installed. Such a station may include several "radio stations" defined above (i.e. several sets of receivers or transmitters installed in one building but functioning independently, and several antennas installed on a field next to the building). This definition of a radio station is more often referred to as a transmitter site, transmitter station, transmission facility or transmitting station [...More...]
