Masts of the Rugby VLF transmitter in England

Steel lattice tower

Radio masts and towers are, typically, tall structures designed to support antennas (also known as aerials in the UK) for telecommunications and broadcasting, including television. They are among the tallest man-made structures. Similar structures include electricity pylons and towers for wind turbines.

Mast or tower?

The terms "mast" and "tower" are often used interchangeably. However, in engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. A schematic image of two cantilevers. ... KVLY-TV mast, which is guy-wire supported. ...

Masts tend to be cheaper to build, but because they require an extended area surrounding them to accommodate stay blocks, towers are more commonly used in cities where land is in short supply.

There are a few borderline designs which are partly free-standing and partly guyed. For example:

• The Gerbrandy tower consists of a self-supporting tower with a guyed mast on top.
• The few remaining Blaw-Knox towers do the opposite: they have a guyed lower section surmounted by a freestanding part.
• Zendstation Smilde a tall tower with a guyed mast on top (guys go to ground)
• Torre de Collserola a guyed tower, with a guyed mast on top. (Tower portion is not free-standing.)

Materials

Steel lattice

The steel lattice is the most widespread form of construction. It provides great strength, low wind resistance and economy in the use of materials. Such structures are usually triangular or square in cross-section.

When built as a stayed mast, usually the whole mast is parallel-sided. One exception is the Blaw-Knox type. This 808-foot-tall Blaw-Knox tower is the tallest in the United States, and belongs to WSM. It is located in the Nashville, Tennessee suburb of Brentwood. ...

When built as a tower, the structure may be parallel-sided or taper over part or all of its height. When constructed of several sections which taper exponentially with height, in the manner of the Eiffel Tower, the tower is said to be an Eiffelized one. The Crystal Palace tower in London is an example. The Eiffel Tower (French: , ) is an iron tower built on the Champ de Mars beside the Seine River in Paris. ... The Crystal Palace transmitting station is a broadcasting and telecommunications site in the Crystal Palace area of the London Borough of Bromley, England (grid reference TQ339712). ...

Tubular steel

Some masts are constructed out of steel tubes. In the UK, these were the subject of collapses at the Emley Moor and Waltham TV stations in the 1960s. Masts and towers can collapse due to natural disasters, such as storms and fires; from engineering defects; and from accidents or sabotage. ...

Reinforced concrete

Reinforced concrete towers are relatively expensive to build but provide a high degree of mechanical rigidity in strong winds. This can be important when antennas with narrow beamwidths are used, such as those used for microwave point-to-point links, and when the structure is to be occupied by people.

In Germany and the Netherlands most towers constructed for point-to-point microwave links are built of reinforced concrete, while in the UK most are lattice towers. Reinforced concrete at Sainte Jeanne dArc Church (Nice, France): architect Jacques Dror, 1926–1933 Reinforced concrete, also called ferroconcrete in some countries, is concrete in which reinforcement bars (rebars) or fibers have been incorporated to strengthen a material that would otherwise be brittle. ...

Concrete towers can form prestigious landmarks, such as the CN Tower in Toronto. As well as accommodating technical staff, these buildings may have public areas such as observation decks or restaurants. This article is about the CN Tower in Toronto. ...

The Stuttgart TV tower was the first tower in the world to be built in reinforced concrete. It was designed in 1956 by the local civil engineer Fritz Leonhardt. The Fernsehturm Stuttgart (TV Tower Stuttgart) is the worlds first TV tower built from concrete (and prototype for many towers of that kind all over the world). ...

Fibreglass poles are occasionally used for low-power non-directional beacons or medium-wave broadcast transmitters. There is a disputed proposal to merge this article with glass-reinforced plastic. ...

Wood

There are fewer wooden towers now than in the past. Many were built in the UK during World War II because of a shortage of steel. In Germany before World War II wooden towers were used at nearly all medium-wave transmission sites, but all of these towers have since been demolished, except for the Gliwice Radio Tower.

Other types of antenna supports and structures

Poles

Shorter masts may consist of a self-supporting or guyed wooden pole, similar to a telegraph pole. Sometimes self-supporting tubular galvanized steel poles are used: these may be termed monopoles. Hot-dip galvanizing is the process of coating iron or steel with a thin zinc layer by passing the steel through a molten bath of zinc at a temperature of around 460°C. Zinc rusts to form zinc oxide, a fairly strong material that stops further rusting, protecting the steel... In physics, magnetic monopole is a term describing a hypothetical particle that could be quickly clarified to a person familiar with magnets but not electromagnetic theory as a magnet with only one pole. In more accurate terms, it would have net magnetic charge. Interest in the concept stems from particle...

Buildings

In some cases, it is possible to install transmitting antennas on the roofs of tall buildings. In North America, for instance, there are transmitting antennas on the Empire State Building, the Sears Tower, and formerly on the World Trade Center towers. When the buildings collapsed, several local TV and radio stations were knocked off the air until backup transmitters could be put into service.^[1] Such facilities also exist in Europe, particularly for portable radio services and low-power FM radio stations.

Disguised cell-sites

Some mobile phone masts are disguised as trees or flagpoles to reduce their visual impact. By contrast, this pink and blue Barber's pole style mast in Durham, England, stands out as a feature in the street.

Many people view bare cellphone towers as ugly and an intrusion into their neighbourhoods. Even though people increasingly depend upon cellular communications, they are opposed to the bare towers spoiling otherwise scenic views. Many companies offer to 'hide' cellphone towers as trees, church towers, flag poles, water tanks and other features.^[2] There are many providers that offer these services as part of the normal tower installation and maintenance service. These are generally called "stealth towers" or "stealth installations". Barber pole, ca. ... Durham (IPA: locally, in RP) is a small city and main settlement of the City of Durham district of County Durham in North East England. ... For other uses, see England (disambiguation). ... Cellular redirects here. ...

The level of detail and realism achieved by disguised cellphone towers is remarkably high; for example, such towers disguised as trees are nearly indistinguishable from the real thing, even for local wildlife (who additionally benefit from the artificial flora^[3]). Such towers can be placed unobtrusively in national parks and other such protected places, such as towers disguised as cacti in Coronado National Forest.^[4] This article is about national parks. ... Subfamilies Cactoideae Maihuenioideae Opuntioideae Pereskioideae See also taxonomy of the Cactaceae A cactus (plural: cacti, cactuses, or cactus) is any member of the succulent plant family Cactaceae, native to the Americas. ...

Even when disguised, however, such towers can create controversy; a tower doubling as a flagpole attracted controversy in 2004 in relation to the U.S. Presidential campaign of that year, and highlighted the sentiment that such disguises serve more to allow the installation of such towers in subterfuge away from public scrutiny rather than to serve towards the beautification of the landscape.^{[original research?][5]} Presidential election results map. ...

Mast radiators

Main article: Mast radiator

A mast radiator is a radio tower or mast in which the whole structure works as an antenna. It is used frequently as a transmitting antenna for long or medium wave broadcasting. A typical mast radiator Base feed: mast is fed from Aerial Tuning Unit on right via conductor to top of brown ceramic insulator. ... Longwave radio frequencies are those below 500 kHz, which correspond to wavelengths longer than 600 meters. ... Mediumwave radio transmissions (sometimes called Medium frequency or MF) are those between the frequencies of 300 kHz and 3000 kHz. ...

Structurally, the only difference is that a mast radiator may be supported on an insulator at its base. In the case of a tower, there will be one insulator supporting each leg.

Telescopic, pump-up and tiltover towers

A special form of the radio tower is the telescopic mast. These can be erected very quickly. Telescopic masts are used predominantly in setting up temporary radio links for reporting on major news events, and for temporary communications in emergencies. They are also used in tactical military networks. They can save money by needing only withstand high winds when lowered, and as such are widely used in amateur radio. Amateur radio station with modern solid-state transceiver featuring LCD and DSP capabilities Amateur radio, often called ham radio, is both a hobby and a service that uses various types of radio communications equipment to communicate with other radio amateurs for public service, recreation and self-training. ...

Telescopic masts consist of two or more concentric sections and come in two principal types:

• Pump-up masts are often used on vehicles and are raised to their full height pneumatically or hydraulically. They are usually only strong enough to support fairly small antennas.
• Telescopic lattice masts are raised by means of a winch, which may be powered by hand or an electric motor. These tend to cater for greater heights and loads than the pump-up type. When retracted, the whole assembly can sometimes be lowered to a horizontal position by means of a second tiltover winch. This enables antennas to be fitted and adjusted at ground level before winching the mast up.

Balloons and kites

A tethered balloon or a kite can serve as a temporary support. It can carry an antenna or a wire (for VLF, LW or MW) up to an appropriate height. Such an arrangement is used occasionally by military agencies or radio amateurs. The American broadcasters TV Martí broadcast a television program to Cuba by means of such a balloon. A captive balloon was also used for the British GQV experimental transmitter in 2003. For other uses, see Balloon (disambiguation). ... Yokaichi Giant Kite Festival held on the fourth Sunday every May in Higashiomi, Shiga, Japan Kite flying is the activity of flying tethered man-made objects in wind. ... TV Martí was created by the US Government to provide news and current affairs programming to Cuba. ...

Other special structures

For two VLF transmitters wire antennas spun across deep valleys are used. The wires are supported by small masts or towers or rock anchors. See List of spans: Antenna spans across valleys. The same technique was also used for the Criggion VLF transmitter. Very low frequency or VLF refers to radio frequencies (RF) in the range of 3 to 30 kHz. ... An incomplete list of remarkable spans, either used for powerline crossings of rivers, sea straits or valleys, as antenna or for aerial tramways. ... The VLF transmitter Criggion is a VLF transmitter for 19. ...

For ELF-transmitters ground dipole antennas are used. Such structures require no tall masts. They consist of two electrodes buried deep in the ground at least a few dozen kilometres apart. From the transmitter building to the electrodes overhead feeder lines run. These lines look like powerlines of the 10 kV level and are installed on similar pylons. A Ground dipole (alt: Ground antenna) is a special type of antenna which consists of two electrodes positioned in the ground. ...

Design features

Economic and aesthetic considerations

• The cost of a mast or tower is roughly proportional to the square of its height.
• A guyed mast is cheaper to build than a self-supporting tower of equal height.
• A guyed mast needs additional land to accommodate the guys, and is thus best suited to rural locations where land is relatively cheap. A tower will fit into a much smaller plot.
• A steel lattice tower is cheaper to build than a concrete tower of equal height.
• Two small towers may be less intrusive, visually, than one big one; especially if they look identical.
• Towers look less ugly if they and the antennas mounted on them appear symmetrical.
• Concrete towers can be built with aesthetic design - and they are, especially in Continental Europe. They are sometimes built in prominent places and include observation decks or restaurants.

Masts for HF/shortwave antennas

For transmissions in the shortwave range, there is little to be gained by raising the antenna more than a few wavelengths above ground level. Shortwave transmitters rarely use masts taller than about 100 metres. A solid-state, analog shortwave receiver Shortwave radio operates between the frequencies of 3 MHz (3,000 kHz) and 30 MHz (30,000 kHz) [1] and came to be referred to as such in the early days of radio because the wavelengths associated with this frequency range were shorter than... For other uses, see Wavelength (disambiguation). ...

Access for riggers

Because masts, towers and the antennas mounted on them require maintenance, access to the whole of the structure is necessary. Small structures are typically accessed with a ladder. Larger structures, which tend to require more frequent maintenance, may have stairs and sometimes a lift. For other uses, see Ladder (disambiguation). ...

Aircraft warning lamps

Taller structures are often equipped with aircraft warning lamps, usually red, to warn pilots of the structure's existence. In the past, ruggedized and under-run filament lamps were used to maximise the bulb life. Nowadays such lamps tend to use LED arrays. Aircraft warning lights are high intensity lighting devices that are attached to tall structures and used as collision avoidance measures. ... LED redirects here. ...

Wind-induced oscillations

One problem with radio masts is the danger of wind-induced oscillations. This is particularly a concern with steel tube construction. One can reduce this by building cylindrical shock-mounts into the construction. One finds such shock-mounts, which look like cylinders thicker than the mast, for example, at the radio masts of DHO38 in Saterland. There are also constructions, which consist of a free-standing tower (usually from reinforced concrete), onto which a guyed radio mast is installed. The best known such construction is the Gerbrandy Tower in Lopik (the Netherlands). Further towers of this building method can be found near Smilde (the Netherlands) and Waldenburg (Baden-Württemberg, Germany).
