ANTENNA TOWER Russian patent published in 2006 - IPC E04H12/00 

FIELD: towers, masts, poles, chimney stacks, water-towers, particularly antenna towers for communication service adapted to mount different wireless antennas and for lighting and other industrial structures.

SUBSTANCE: antenna tower is made as multi-sided shell with cross-section varying along tower length and increasing in top-down direction. The shell has cross-section shaped as rectilinear dodecahedron and has solid walls or includes several sections. The lower section is solid, another sections are made of several segments connected with each other and obtained by serial three-dimensional bending of trapezoid blanks so that ribs and faces are formed. The segments have inner flanges. The sections are connected one to another so that the sections are turned one relative another and inner flanges of each next section segments are shifted 60° in horizontal plane with respect to that of previous section segments.

EFFECT: increased reliability and resistance to wind, reduced labor inputs for antenna production and mounting, as well as improved vandalism protection of electrical communication lines (feeders, cables and so on).
