In the following there are lists of sites of notable radio transmitters. During the early history of radio many countries had only a few high power radio stations, operated either by the government or large corporations, which broadcast to the population or to other countries. Because of the large number of transmission sites, this list is not ...
Example of a radio map estimate using STORM, a transformer-based radio map estimator. Signal strength maps quantify signal strength at each location. Formally, a signal strength map can be seen as a function γ ( r ) {\displaystyle \gamma (\mathbf {r} )} that provides a signal strength metric for each location r {\displaystyle \mathbf {r} } .
The act of measuring the direction is known as radio direction finding or sometimes simply direction finding (DF). Using two or more measurements from different locations, the location of an unknown transmitter can be determined; alternately, using two or more measurements of known transmitters, the location of a vehicle can be determined.
The ITU conference held in Stockholm, Sweden in 1961 [6] led to the planning of the UHF television broadcasting network in the United Kingdom. [7] A high power UHF television transmitter was allocated for 625-line colour transmissions close to Banff, with the broadcasting channels 23/26/29/33 broadcasting at 100 kW effective radiated power (erp).
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.

Bank-1 to the north, length of 1.3 kilometres (0.81 mi), bank-2 with 1.9 kilometres (1.2 mi) to the south-east and bank-3 with 1 kilometre (0.62 ...
Radiolocation, also known as radiolocating or radiopositioning, is the process of finding the location of something through the use of radio waves.It generally refers to passive, particularly radar—as well as detecting buried cables, water mains, and other public utilities.
Unlike the Delrac system, Dectra was essentially the normal Decca Navigator system with the modification of several existing transmitter sites. [7] These were located at the East Newfoundland and Scottish chains, which were equipped with larger antennas and high-power transmitters, broadcasting 20 times as much energy as normal chain stations.
