** Description:** The method of calculation is developed effective surface dispersions of eventual cylinder with the section of resonance sizes. The model of Makdonal'da, supposing a presence at the body of simultaneously ideally reflecting and ideally taking in properties, is utillized. Expressions over, allowing to expect the field in a distant area, dissipated long ideally conducting and ideally magnetic a cylinder, are brought. The calculations of effective surface of dispersion of model of aerial of the radiolocation station of P-18 are conducted. Of principle possibility of substantial decline of effective surface of dispersion of aerial of RLS P-18 is shown due to application radio absorbent coverages. Results over of row of calculations of diagram of effective surface of dispersion of model of aerial are brought RLS P-18.
