In a vertical radio-frequency wave radiating structure to be climbed by a person, there is provided a fall prevention system. This fall prevention system includes a safety rope, made of a radio-frequency wave resistant material, to receive an individual rope grab. A first end of the safety rope is attached to an upper section of the vertical structure, while the second end of that safety rope is attached to a lower section of the vertical structure. Preferably, the safety rope comprises a polyurethane resin impregnated aramid fiber core protected with a thick extruded jacket of polyurethane.
