Each station was originally equipped with a 250 watt General Electric transmitter and four-section RCA Pylon horizontally polarized antenna, providing 1.3 kW ERP. The Rural Radio Network (RRN) was an interconnected group of six commercial FM radio stations spread across upstate New York and operated from Ithaca, New York—the first all-radio ...
The design designation of these masts is 30107 KM and they are exclusively used for FM and TV and are between 150–200-metre (490–660 ft) tall with one exception. The exception being the mast in Vinnytsia which has height of 354 m (1161 ft) and is currently the tallest guyed tubular mast in the world after the Belmont transmitting station ...
This phase starts from initial network deployment and involves collecting measurement data on a regular basis which could be via drive testing or centralised collection. The data is then used to plan new sites or to optimize the parameter settings (e.g. antenna orientation, downtilting, frequency plan) of existing sites.
Coverage maps are designed to indicate the service areas of radiocommunication transmitting stations. Typically these may be produced for radio or television stations, for mobile telephone networks and for satellite networks. For satellite networks, a coverage map is often known as a footprint.
(The sequence of antenna systems on a typical TV-FM station may be from bottom to top; VHF-2, VHF-3 and UHF.) Microwave stations are also high altitude stations. Although high altitude is desirable also in GSM , the operators may use low power intracity stations for areas of high population density.
In US broadcasting, service contour (or protected contour) refers to the area in which the Federal Communications Commission (FCC) predicts coverage.. The FCC calculates FM and TV contours based on effective radiated power (ERP) in a given direction, the radial height above average terrain (HAAT) in a given direction, the FCC's propagation curves, and the station's class.
The FCC has divided the Contiguous United States into three zones for the determination of spacing between FM and TV stations using the same frequencies. FM and TV stations are assigned maximum ERP and HAAT values, depending on their assigned zones, to prevent co-channel interference. FM broadcast zones in the U.S.
An antenna farm, satellite dish farm or dish farm is an area dedicated to television or radio telecommunications transmitting or receiving antenna equipment, such as C, K u or K a band satellite dish antennas, UHF/VHF/AM/FM transmitter towers or mobile cell towers.
