of 359.7 metres was finished. In 1990 the plant was taken over by the Deutsche Telekom AG. At first it was planned to shut down the facility: so the cage aerial at the main mast was dismantled and the transmitting power of the long wave transmitter was reduced occasionally to 100 kilowatts. In the second half of the 1990s a reorientation occurred. The long wave transmitter was modernized and the main antenna tower received a new cage aerial. Also the transmitting power of the long wave transmitter was increased again to 500 kW. In the year 2000 a , guyed, grounded mast of lattice steel carrying a cage aerial for medium wave was built. This took over the function of the former Transmitter Berlin-Koepenick and served apart from the spreading of the program of MEGARADIO also for transmitting of programs of the Voice of Russia, partly in the Simulcast mode. The long wave transmitter changed over on 29 August 2005 as first German large transmitter to Digital Radio Mondiale. The long wave transmitter ceased operation on December 31, 2014 as part of the general shutdown in Germany of AM radio services to the public. The mast continued to support VHF radio antennas providing FM broadcast services. The triangle plane antenna masts (3 of them, 150 meters high each) were demolished in 2007, with the antenna itself having been taken out of service in 2003. In 2015, the 129-meter mast was demolished; transmission from it had ceased in 2014. The last mast (the highest, main mast of 359.7 meters height) at the site was demolished in 2017, and radio operations at the site ended.
