Caltanissetta Transmitter Station
The Caltanissetta Transmitter Station (Italian: ''Trasmettitore di Caltanissetta'' or ''Antenna Rai di Caltanissetta'') was a plant, then idle, for broadcast on longwave, mediumwave and shortwave; tipe guyed mast. The transmitter is insulated against ground. Its main element was an omnidirectional antenna 286 meters high, which holded the record for the tallest structure in Italy; it stood on a hill 689m above sea level; The top antenna was placed at above sea level. After a series of decades-long debates on its fate and also because of its deterioration, the transmitter has been demolished on 23 July 2025.

Caltanissetta
Caltanissetta (Sicilian language, Sicilian: ''Cartanissètta)'' is an Italian comune with a population of 58,012 inhabitants, serving as the capital of the Province of Caltanissetta, free municipal consortium of Caltanissetta in Sicily. The earliest inhabitants of the surrounding territory were the Sicani, who established various settlements as early as the 19th century BC. However, the modern city was likely founded in the 10th century during the Islamic Sicily, Islamic period in Sicily, when the name "Caltanissetta" is believed to have originated, though alternative theories have been proposed over time. Under the Normans, it was transformed into a feudal holding, and after various transitions, it came under the control of the House of Montcada, Montcada of Paternò in 1405. This noble family governed the County of Caltanissetta until 1812, leaving behind the Baroque-style Palazzo Moncada, constructed in the 17th century. From the 19th century onward, Caltanissetta experienced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sicily
Sicily (Italian language, Italian and ), officially the Sicilian Region (), is an island in the central Mediterranean Sea, south of the Italian Peninsula in continental Europe and is one of the 20 regions of Italy, regions of Italy. With 4.7 million inhabitants, including 1.2 million in and around the capital city of Palermo, it is both the largest and most populous island in the Mediterranean Sea. Sicily is named after the Sicels, who inhabited the eastern part of the island during the Iron Age. Sicily has a rich and unique culture in #Art and architecture, arts, Music of Sicily, music, #Literature, literature, Sicilian cuisine, cuisine, and Sicilian Baroque, architecture. Its most prominent landmark is Mount Etna, the tallest active volcano in Europe, and one of the most active in the world, currently high. The island has a typical Mediterranean climate. It is separated from Calabria by the Strait of Messina. It is one of the five Regions of Italy#Autonomous regions with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Longwave
In radio, longwave (also spelled long wave or long-wave and commonly abbreviated LW) is the part of the radio spectrum with wavelengths longer than what was originally called the medium-wave (MW) broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of LW, MW, and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short' (i.e. VHF, UHF, and microwave). In contemporary usage, the term ''longwave'' is not defined precisely, and its intended meaning varies. It may be used for radio wavelengths longer than 1,000 m i.e. frequencies smaller than 300 kilohertz (kHz), including the International Telecommunication Union (ITU) low frequency (LF, 30–300 kHz) and very low frequency (VLF, 3–30 kHz) bands. Sometimes the upper limit is taken to be higher than 300 kHz, but not above the start of the medium wave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortwave Radio
Shortwave radio is radio transmission using radio frequencies in the shortwave bands (SW). There is no official definition of the band range, but it always includes all of the High frequency, high frequency band (HF), which extends from 3 to 30 MHz (approximately 100 to 10 metres in wavelength). It lies between the Medium frequency, medium frequency band (MF) and the bottom of the Very high frequency, VHF band. Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere. Therefore, short waves directed at an angle into the sky can be reflected back to Earth at great distances, beyond the horizon. This is called skywave or "skip" radio propagation, propagation. Thus shortwave radio can be used for communication over very long distances, in contrast to radio waves of higher frequency, which travel in straight lines (line-of-sight propagation) and are generally limited by the visual horizon, ...

Guyed Mast
A guyed mast is a tall thin vertical structure that depends on guy lines (diagonal tensioned cables attached to the ground or a base) for stability. The mast itself has the compressive strength to support its own weight, but does not have the shear strength to stand unsupported or bear loads. It requires guy lines to stay upright and to resist lateral (shear) forces such as wind loads. Examples include masts on sailing vessels, towers for telecommunications, meteorology, and masts on cranes, power shovels, draglines, and derricks, starting with the simple gin pole. Applications The principal applications of guyed masts are the masts of sailing vessels, guyed towers, and as the main tower of heavy equipment such as cranes, power shovels, draglines, and derricks, the simplest of which is the gin pole. Guyed masts are frequently used for radio masts and towers. The mast can either support radio antennas (for VHF, UHF and other microwave bands) mounted at its top, or th ...
