Radio masts and towers in the context of "BASE jumping"

Tokyo Tower (東京タワー, Tōkyō Tawā; pronounced [toːkʲoː taꜜɰᵝaː] ), a.k.a. Japan Radio Tower (日本電波塔, Nippon denpatō) is a communications and observation tower in the district of Shiba-koen in Minato, Tokyo, Japan, completed in 1958. At 332.9 m (1,092 ft), it was the tallest tower in Japan until the construction of Tokyo Skytree in 2012. It is a lattice tower inspired by the Eiffel Tower, and is painted white and international orange to comply with air safety regulations.

The tower's main sources of income are tourism and antenna leasing. FootTown, a four-story building directly under the tower, houses museums, restaurants, and shops. Departing from there, guests can visit two observation decks. The two-story Main Deck (formerly known as the Main Observatory) is at 150 m (490 ft), while the smaller Top Deck (formerly known as the "Special Observatory") reaches a height of 249.6 m (819 ft). The names were changed following renovation of the top deck in 2018. The tower is repainted every five years, taking a year to complete the process.

The BT Communication Tower, more commonly known as the BT Tower, is a Grade II listed communications tower in Fitzrovia, London, England, owned by MCR Hotels. It has also been known as the GPO Tower, the Post Office Tower, and the Telecom Tower. The main structure is 177 metres (581 ft) high, with aerial rigging bringing the total height to 189 metres (620 ft).

Upon completion in 1964, it was the tallest structure in London and remained so until 1980. Butlins managed a revolving restaurant in the tower from 1966 until 1980. A 360° LED screen displays news across central London.

A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure. They are used commonly for ship masts, radio masts, wind turbines, utility poles, and tents. A thin vertical mast supported by guy wires is called a guyed mast. Structures that support antennas are frequently of a lattice construction and are called "towers". One end of the guy is attached to the structure, and the other is anchored to the ground at some distance from the mast or tower base. The tension in the diagonal guy-wire, combined with the compression and buckling strength of the structure, allows the structure to withstand lateral loads such as wind or the weight of cantilevered structures. They are installed radially, usually at equal angles about the structure, in trios and quads. As the tower leans a bit due to the wind force, the increased guy tension is resolved into a compression force in the tower or mast and a lateral force that resists the wind load. For example, antenna masts are often held up by three guy-wires at 120° angles. Structures with predictable lateral loads, such as electrical utility poles, may require only a single guy-wire to offset the lateral pull of the electrical wires at a spot where the wires change direction.

Conductive guy cables for radio antenna masts can catch and deflect radiation in unintended directions, so their electrical characteristics must be included in the design. Often the guy wire is divided by strain insulators into isolated sections whose lengths are not resonant with the transmission frequencies.

A television antenna, also called a television aerial (in British English), is an antenna specifically designed for use with a television receiver (TV) to receive terrestrial over-the-air (OTA) broadcast television signals from a television station. Terrestrial television is broadcast on frequencies from about 47 to 250 MHz in the very high frequency (VHF) band, and 470 to 960 MHz in the ultra high frequency (UHF) band in different countries.

Television antennas are manufactured in two different types: indoor and outdoor antennas. Indoor antennas are designed to be located on top of or next to the television set, but are ideally placed near a window in a room and as high up as possible for the best reception. The most common types of indoor antennas are the dipole ("rabbit ears"), which work best for VHF channels, and loop antennas, which work best for UHF. Outdoor antennas on the other hand are designed to be mounted on a mast on top of the owner's house, or in a loft or attic where the dry conditions and increased elevation are advantageous for reception and antenna longevity. Outdoor antennas are more expensive and difficult to install but are necessary for adequate reception in fringe areas far from television stations; the most common types of these are the Yagi, log periodic, and (for UHF) the multi-bay reflective array antenna.

A lattice tower, or truss tower, is a freestanding vertical framework tower. This construction is widely used in transmission towers carrying high-voltage electric power lines, in radio masts and towers (both self-radiating towers and those that support aerials) and in observation towers. Its advantage is good shear strength at a much lower weight than a tower of solid construction would have as well as lower wind resistance.

In structural engineering, the term lattice tower is used for a freestanding structure, while a lattice mast is a guyed mast supported by guy lines. Lattices of triangular (three-sided) cross-section are most common, particularly in North America. Square (four-sided) lattices are also widely used and are most common in Eurasia. A lattice towers is often designed as either a space frame or a hyperboloid structure.

A cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network. The raised structure typically supports antennae and one or more sets of transmitter/receivers transceivers, digital signal processors, control electronics, a GPS receiver for timing (for CDMA2000/IS-95 or GSM systems), primary and backup electrical power sources, and sheltering.

Some companies provide infrastructure services for cellular networks, including site acquisition, construction, and ongoing maintenance. These third-party providers can manage multiple sites and coordinate network upgrades, helping operators expand coverage efficiently. Such services are offered by companies that specialize in tower management and network support.

Küçük Çamlıca TV & Radio Tower (Turkish: Küçük Çamlıca TV-Radyo Kulesi), or simply Çamlıca Tower, (Turkish pronunciation: [tʃamlɯdʒa]) is a telecommunications tower with observation decks and restaurants on Little Çamlıca Hill in Üsküdar district of Istanbul, Turkey.

The total height of the tower is 369 metres (1,211 ft), 221 metres (725 ft) of which is a 49-storey reinforced concrete structure with 18 metres (59 ft) below ground. The height of the tower's steel antenna is 168 metres (551 ft). With a total height of 587 metres (1,926 ft) above sea level, it carries the title of the highest structure in Istanbul.
