Abstract

Mast for a source of electromagnetic waves, comprising a number of peripheral rods (1) extending in vertical direction, the peripheral rods being mutually connected by transverse rods (2), and forming a space for accommodating the electromagnetic wave source in, or at the top of, the mast. The mast is provided with a stabilization device for reducing uncontrollable natural vibrations in the event of hypercritical wind speeds, said device being accommodated in, or on top of, the mast. The mast advantageously supports a lining of dishes (7).
