For masts near a half-wavelength high (180 electrical degrees) the mast has a voltage maximum near its base, which results in strong electric fields in the earth above the ground wires near the mast where the displacement current enters the ground. This can cause significant dielectric power losses in the earth. To reduce this loss these ...

The mast can either support radio antennas (for VHF, UHF and other microwave bands) mounted at its top, or the entire structure itself can function as a mast radiator antenna (for VLF, LF, MF). In the latter case, the mast needs to be insulated from the ground. Guyed radio masts are ...
