A broad band HF communications antenna for surface ships has an increased survivability over the currently used twin fan antennas. Capacitively coupling a long, flat conductive strap to existing ship structures helps achieve broadband performance. Integral end sections of the long, flat conductive strap are bent at each end and a dielectric layer with a low dielectric constant is provided along the length of each end section. The end sections and dielectric layers provide the areas needed for capacitive coupling to a mast and stack or other parts of the ships superstructure thereby creating a survivable and broadband HF communications antenna design.
