Stadelheim Transmitter

From Wikipedia, the free encyclopedia

Stadelheim Transmitter was a medium-wave broadcast transmitter in Munich-Stadelheim, built in 1926 in the neighbourhood of the famous prison. As antenna this transmitter, which took up its experimental operation on March 1, 1926 and on April 1, 1926 its final operation, a t-antenna hung up on two 100 meters high free standing steel framework towers. The transmitter used a tube transmitter and a machine transmitter of the company C Lorenz AG. However the machine transmitter had numerous technical problems.

In addition, the transmitting antenna did not work well and was replaced in the autumn of 1926 by a T-antenna hung on two 75 meter high wood framework towers, which were built by the company Kuebler, located in Stuttgart. In the night of 22-23 November 1930 a storm bent both towers at a height of 25 meters; some buildings were also damaged. Transmitting was restarted later that day with an emergency antenna, which was stretched between the tower stumps. The destroyed towers were replaced with two new wood towers with T-antennas, placed farther from the buildings, were built at the turn of the year 1930/31. After the inauguration of the transmitter Ismaning on December 3, 1932 the transmitter Stadelheim was used as a spare transmitter for the Ismaning facility. It might have been used for the last time in November and December 1933, when the transmitter Ismaning was shut down because of maintenance work.
