Deutschlandsender Herzberg/Elster
The Deutschlandsender Herzberg/Elster was a 500 kilowatt longwave transmitter at Herzberg/Elster, which was in service from 1939 to 1945. It used as aerial a 337 metre high guyed steel framework mast with triangular cross section. The mast was used as mast antenna and was therefore mounted on a 0.75 metre high steatite insulator. On its top there was a lenslike structure with a diametre of 25 metres and a height of 4 metres.
Because the mast was under high voltage potential during transmission operation, the flight security lightning was realized in a very unconventional manner. On small poles near the mast multiple rotating skybeamers were mounted which illuminated the lense-like structure on the top.
In April 1945 the transmitter was destroyed by Allied bombing. The mast was not damaged, but it was dismantled by the Russian Army after World war II. Nowadays there are still some remanents of the bsements of the mast.
