The Sender Donebach was a 500-kilowatt long wave radio transmitter operating on 153 kHz and transmitting the program of German public broadcaster Deutschlandfunk.

The facility, which was the property of Media Broadcast, was built between 1965 and 1967 on a former airfield, and entered service on March 10, 1967.

It was part of an omnidirectional aerial, consisting of four 200-metre-high radio masts, which were connected using wires on their tops.

This very efficient transmission aerial led to interference with the Romanian transmitter Braşov on the same frequency, so only 70 kilowatts of power were used, instead of 250.

This facility was remarkable because This Antenna was a popular spot among climbers and Base-Jumpers.
