Bodenseesender, Radio transmitter in Meßkirch-Rohrdorf, Germany.

Bodenseesender is a transmission facility in Meßkirch-Rohrdorf that broadcast medium wave radio programming through a steel framework mast system. The station used multiple guyed masts to distribute signals across southern Germany and nearby regions.

The facility began operating in 1964 with four guyed steel masts that were reduced to two by the mid-1970s. It continued broadcasting until 2012 as part of the region's radio infrastructure.

From 1964 to 1992 the transmitter carried SWF1 on medium wave; on 1 July 2002 SWR cont.ra took over the 666 kHz frequency. Because of its 100 kW power (150 kW until 2007), the signal reached far beyond Meßkirch-Rohrdorf, and the 244-metre mast was the tallest structure in Sigmaringen district. The site is now used by SWR to monitor its transmitter network in the Lake Constance area.

The location was positioned in a rural area surrounded by open fields and forest that helped radio signals spread across the region. This placement allowed for good coverage across southern Germany and neighboring territories.

The 244-metre main mast was the tallest structure in Sigmaringen district. Its guy wires were dimensioned so that, except for the lowest one, they had no intermediate insulators and could be grounded directly at the anchor blocks without disturbing radiation on 666 kHz. One of the four original 137-metre masts was rebuilt in Nierstein, Rhineland-Palatinate.
