An antenna array includes two acutely bent dipole antenna elements placed back-to-back on a printed circuit board with integrated micro-strip balun transformers which a Wilkinson divider drives 180 degrees out of phase. In an embodiment, the antenna array sits on a vertical blade support structure to form a T-Top section.
