Bodenseesender
The Bodenseesender (transmitter of Lake Konstanz) is a radio transmission facility of SWR (until 1998 SWF) near Messkirch-Rohrdorf in Southern Germany for mediumwave (and until 2004 also for shortwave) established in 1964. It is now used for the propagation of SWR Cont.Ra on the medium wave frequency 666 kHz. Until 1978 the aerial of the medium wave transmitter consisted of 4 guyed steel framework masts, which are insulated against ground. In the Mid 70ies one of these masts was dismounted and replaced by a 240 metre high guyed steel framework mast, which is also insulated against ground. At the construction of this mast, the length of the guys were chosen in such way, that they do not disturb the radiation pattern when grounded at the ancre blocks and - without the guy on the lowest level - do not have any separation insulators.
Until October 19th, 2004 there was a shortwave transmitter on the site of the Bodenseesender, which was used to transmit the program of SWR 3 on 7265 kHz.
