Science Fair Projects - List of masts (1517 words) |
 | Radio masts for VLF, LF and MF often act directly as aerials and are therefore often insulated against ground. |
| 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. |
