Possibility of barrage handycaps creation to radioline of the control by explosive devices (RCED) are analysed and generalized. The estimation of power and spatial characteristics of the antenna system is got ultrawideband RTS blocking of RCED. Coming from the tactical considering, as an antenna system for the radiation of handycaps with the spectrum width 100 MHz – 3 GHz it is suggested to utillize the mirror antenna system with an irradiator as conical spiral antenna, the diameter – 1,5 m, polarization - circle. The coefficient of defence efficiency equal one is expected .
