  Mast radiator - Wikipedia, the free encyclopedia
For radio systems in the longwave and mediumwave range the value of the height should be in the range between one sixth and five eighths of the wavelength, with favourite values at the quarter or the half of the radiated wavelength.
For high power transmitters in the MW range, masts with heights around half of the radiated wavelength are preferred because they focus the radiated power better to the ground than structures with heights of quarter wavelengths, which are preferred of economical reasons for low power medium wave transmitters.
For longwave transmitters, however, the construction of masts with heights of half-wave wavelength is, because of economical reasons (and perhaps problems with the flight safety), in most cases impossible.

 Radio masts and towers - Wikipedia, the free encyclopedia
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.
In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna.
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.

Top masts are ranked by pinnacle height; in the case of a tie, the older structure is ranked as higher.
Most of the taller masts are located in the U.S., and the large number of masts of around 2000 feet in height is the result of special US rules limiting structures and objects that go above 2000 feet.
Once again, the list includes guyed masts, almost exclusively radio masts, though a few for other purposes are present (for example, the BREN-Tower.) Self-supporting masts are covered as towers under the List of towers, and the borderline cases are mentioned separately (hybrid designs, under water, etc.) elsewhere on this page.
