A very interesting bit of broadcasting history in Moscow may disappear forever. Designed and built by Vladimir Grigoryevich Shukhov, the Shukhov Tower was completed in 1922. Since that time it has served as a AM broadcasting and later and FM broadcasting tower. In the picture, one can see what looks like a massive FM panel antenna at the top. According to this website: www.shukhov.org, the tower is in very poor shape and is slated to be demolished.
The tower itself is described as 160 Meters (525 feet) tall, hyperboloid steel lattice structure. The design is unique in that it is very strong, yet uses approximately 60-70 percent less steel than a comparable four legged structure like the Eiffel tower. An amazing feat of engineering for its day, when everything was calculated and drawn by hand.
The antenna is a little hard to discern, however, it looks like a horizontally polarized six or eight around 4 bay FM antenna. Could also be low band VHF TV.
Unfortunately, time is running out and little or nothing is being done to protect the steel structure from the elements. The last paint job was more than twenty years ago. The land it currently occupies has some value, and there is talk of putting up a high rise development in its place.

There are lots of videos on youtube and pictures from the wikipedia article. It is an interesting bit of history, if it can be saved it will be a very close run thing.
