Ehndorf transmitter, Communication tower in Arpsdorf, Germany.

The Ehndorf transmitter was a mediumwave facility at Ehndorf, west of Neumünster, consisting of two guyed steel lattice masts 65 metres tall with triangular cross-section, fed at the base. The directional antenna was required to avoid interference with a station on the same frequency in Novi Sad, Serbia. The masts were dismantled in early July 2018.

The facility began operations in November 1967 with a power output of 600 kilowatts from two combined tube transmitters. This infrastructure was part of Cold War era broadcasting capabilities for cross-border radio communication.

From 1967 to 1994, the station broadcasted German language programs from Deutschlandfunk toward East Germany during daytime and foreign programs in evenings.

The masts were dismantled in early July 2018, so nothing of the transmitter remains at the site in Ehndorf, west of Neumünster. Plan the visit as a look at the village and the former antenna field rather than at a standing structure. The site lies in the municipality of Arpsdorf, and no visitor facilities exist there.

The two 65-metre steel lattice masts had a triangular cross-section and were guyed at one level. Their directional antenna pattern was needed to avoid interference with a station on the same frequency in Novi Sad, Serbia, over 1360 kilometres away. The masts were dismantled in early July 2018.
