		For radio systems in the longwave and mediumwave range the value of the height should be in the range between a sixth and five eighth 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 lengths around half of the radiated wavelength are preferred because they focus the radiated power better to the ground than constructions 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.
