Herzogstand Radio Station was a radio communication station built and operated from 1920 to 1946 on the Herzogstand mountain near the Kochelsee in Bavaria, Germany. The plant was conceived by C Lorenz AG to transmit long-wave radio traffic between Germany and the far east, since the existing large radio stations served mainly traffic to the west. From 1930 the mechanism was used by the Technical University of Munich for ionosphere research.
As the costs of erecting a sufficiently high mast were exorbitant, a suspended antenna system in the mountains was conceived. The 1,735 metres Herzogstand mountain between the Kochelsee and Walchensee in the Bavarian alps seemed particularly suitable for several reasons: the summit is accessible all year round, sufficient water for drinking and cooling was available, and the conveniently nearby Lake Walchen Power Plant promised a safe, economical power supply. The design of the antenna was unprecedented. As free span a distance of over 2,5 km resulted to reach with a difference in height of 800 m. around a sufficient height of the antenna above ground should the rope at the lower point of suspension horizontally accumulate, which required an enormous tension of the rope. Due to that load by wind, in addition, by snow and ice, additionally which can be expected, only steel wire of highest firmness was applicable. A first thin steel cable became strained in the summer 1920. Radiation measurements resulted in the 1.3 subject radiation and/or the 1.6 subject in the comparison to the overseas Eilvese transmitter in the case of wavelengths of 12,6 km and 9.7 km in the comparison to the high-power radio station Nauen. Up to the early summer 1925 3 antennas were pulled fan-like for the summit burr of the duke conditions. In order to improve conductivity, the steel cable was coated with aluminum. The rope in a particularly developed Seilereianlage within the summit range were manufactured. Around the summit the antennas were fixed to concreted steel anchors. At the lower tie points a mobile suspension system was used, in order to allow the cables to stretch when loaded with snow and ice.
