Sender Bielstein

From Wikipedia, the free encyclopedia

The Sender Bielstein (Transmitter Bielstein) is a FM- and TV-broadcasting facility on the 393 metre high Bielstein mountain in the Forest of Teutoburg, Northrine-Palatine, Germany. Bielstein transmitter, which is property of WDR and used for transmittng its programmes was established in 1951. It used until 1954 a 60 metre tall mast. This mast was replaced in 1954 by a 102 metre tall antenna tower. However this mast was not able to supply the whole area with FM and TV-programmes and so a taller antenna mast was soon planned. Finally in 1968 constructon work started for a 298 metre tall guyed steel tube mast. This mast, which was completed in 1970 enabled a satisfactoring supply of FM- and TV-programmes in the area. On January 15th, 1985 at 6.26 MST the mast as result of too much iceload and great wind-induced stress, one of the upper guys of the mast were torn off. As result the mast bent and cracked 160 metres above ground. Afterwards also the rest of the mast collapsed as the fallng upper parts destroyed the guys holding its lower parts. Already on the afternoon of January 15th, 2006 as replacement for the first FM-transmitter which used the mast went in the air again, by using a communication tower of Deutsche Telekom as transmissin site. Three days later, TV broadcasting was also restored. On Bielstein mountain, one begun immediately building up a 85 metre tall auxiliary transmission mast for transmitting the TV and FM-programmes which were until the collapse radiated from the Bielstei transmission mast. Of course, reception of the signals radiated from this auxiliary mast was much worse than from the former 298 metre mast and so construction work for a new 302 metre tall guyed lattice steel mast started soon, which was completed in August 1986. In April 2006 the mast got a new antenna for DVB-T broadcasting, which reduced its height to 290 metres.
