an antenna for medium wave transmission, like today's backup broadcasting tower. Saint Chrischona was already in use since 1954, a broadcasting tower that was 30 m high at that time which transferred the Swiss television program up to this time. Today's tower of Saint Chrischona carries broadcasting antennas for Swiss Radio (DRS) and the “Southwest German Radio” (SWR). Because of this unique construction, it is said that the tower could remain standing during the high winds of a hurricane, where wind speeds appear up to 220 km/h, with an oscillation of only 40 cm.
