A low profile bi-directional antenna is provided for mounting directly to a metal structure, or some other conductive or semi-conductive surface. The antenna includes an insulating antenna tray, a conductive ground plane mounted to a surface of the antenna tray, first and second radiating elements extending from the ground plane, and a radome covering the radiating elements and fastened to the insulating antenna tray. First and second reflector elements are mounted to the surface of the antenna tray on the lateral sides of the ground plane. The reflectors are electrically connected to the ground plane. The radiating elements are supported above and to the lateral sides of the ground plane and reflector elements by support members mounted at acute angles to the ground plane. An RF connector is provided for coupling RF signals to and from the first and second radiating elements.
