Annotation: Guyed masts for cellular nets are often on roofs of buildings placed. This article reviews the research results of wind stream properties over a building surface in the wind tunnel. Importance of this research is highlighted. The open soaking-up wind tunnel of short type was for the experiment used. An overview of the main parameters of a wind tunnel and of the used measuring devices is given. Measurements of wind pulsing speeds without the building model and with the considered model of a building were carried out. There are the profile of average speed of a wind, the profile of intensity of turbulence, the profile of spectral density for all high-rise points of a profile depending on frequency, the profile of specifying factor of average wind speed amplification received. Improvement of a wind pressure calculation procedure for the guyed masts located on a roof of buildings taking into account caused by own aerodynamic properties wind pressure increase over a building is offered.
Keywords: guyed mast, basic building, laboratory experiment, wind tunnel, speed of a wind, design procedure of wind pressure.
