Interesting Facts/Records (in own words): Zorawina radio mast is a 258 metre tall guyed mast. It was used as mast radiator for 1206 kHz and was one of the few mast antennas whose height was in the same order as the used wavelength ( this is very unusual. If no special measures as multile feeding or cage antennas on the mast are installed, a mast radiator taller than five eighth of wavelength is not realized, as it produces too much skywaves, whch results in fading. Interestingly the mast does not look like a mast, which can be fed at several levels).
After the mediumwave transmitter, which used it as antenna was shut down in the Nintes, it was transformed in a mast for FM- and TV-broadcasting. Meanwhile its guys, which were divided by insulators were replaced by guys without insulators ( http://pl.wikipedia.org/wiki/%C5%BB%C3%B3rawina ).

So, the Sendeturm Rothsürben was not dismantled in 1945?

It estonished me also. I believed, it was demolished by the retracting German troops as they did at many sites.
Before this source, I found no evidence that the tower survived the end of World War II.

Are you sure they are talking about the Sendeturm Rothsürben, though? I don't see that name mentioned, nor do I see a height of 140 meters listed anywhere on that page. So, perhaps they are talking about another structure?

By using Poltran, a Polish-English online translator, I found out that the tower demolished in 1990 was a wooden tower.
Building wooden radio towers went very uncommon after 1935 and so there is no doubt, that this was the wooden tower built in 1932.
