The source of high-power ultrawideband (UWB) radiation based on single compact antenna excited with 1-ns bipolar pulse has been created. Antenna input pulse amplitude is up to 120-kV and pulse repetition rate up to 100 Hz. The antenna efficiency by peak power was 60%. The peak power of the source was 170 MW. The antenna pattern width by half-power is 100/spl deg/ for the H-plane and 105/spl deg/ for the E-plane. The efficient voltage of the source equal to product of the peak field strength and the distance made /spl sim/130 kV.
