A construction is grounded and the calculation of spatial and temporal characteristics of ultrawideband (UWB) mirror antenna with an irradiator as a conical spiral is conducted. The form of UWB signal is certain at different position of view point. It is marked that antennal has circular polarization and ceiling coefficient 30. The expected temporal dependences of UWB signals in a front semi-sphere allow to estimate efficiency of the barrage handicaps use for radioline of management explosive devices, and in a back semi-sphere – to give the estimation of electromagnetic situation of UWB RTS with other radio engineerings facilities, including communication means.
