Civil emergency service antennas near Nyon in Switzerland
The structure in the centre of the photograph is a bi-conical monopole broadband HF antenna. This has good ground-wave and sky-wave radiation characteristics. If you look carefully you can see the wires running up from the feed point at the base of the support mast to the circular waist disk and then up to the top of the antenna. Its located at a civil emergency services site near Nyon in Switzerland. There was also one of these at Cape Shank in Victoria.
