Chimney-like telecommunication towers in Russia

Most telecommunication towers in Russia ( and other parts of former Soviet Union) are free-standing lattice towers. But there are also several chimney-like telecommunication towers ( I think most of them steel tube structures as that shown on http://static.panoramio.com/photos/o…l/26833776.jpg which is situated near Lesnoy at 56°05’18"N 37°55’51"E. Where else do such towers exist in Russia? I know from a similiar tower in Yekaterinburg, but there may exist further such towers. When were they built? Are they concrete or steel tube towers?
