A wideband end-fire array including columns or sub-arrays of flared notch radiating elements spaced along an end-fire axis and fed by a true- time-delay corporate feed network. The feed network includes a corporate feed manifold and a plurality of cables connected between a respective manifold port and a balun comprising a corresponding radiating element. The plurality of cables have corresponding electrical line lengths adapted to provide progressive time delays to signals carried between the radiating elements and the feed manifold so as to equalize the time delays due to spacing of the elements along the axis.
