An antenna terminated to a coaxial cable having a center conductor surrounded by a dielectric and a cable braid, wherein the antenna comprises: a substrate having first and second surfaces (32, 34), the substrate having a signal element and a ground element on the first surface, and a ground contact having a base mounted to the first surface of the substrate in electrical connection with the ground element, the ground contact having mounting elements extending from the base, the ground contact having a wire termination terminated to the cable braid of the coaxial cable, characterized by: the mounting elements engaging the second surface such that the substrate is captured between the mounting elements and the base of the ground contact, a signal contact having a base mounted to the first surface of the substrate in electrical connection with the signal element, the signal contact having mounting elements extending from the base, the mounting elements engaging the second surface such that the substrate is captured between the mounting elements and the base of the signal contact, the signal contact having a wire termination terminated to the center conductor of the coaxial cable, the electrical connection between the base of the ground contact and the ground element being a compression connection wherein the base is pressed against the ground element in direct electrical contact with the ground element, by the mounting elements of the ground contact forcing the substrate against the base, the electrical connection between the base of the signal contact and the signal element being a compression connection wherein the base is pressed against the signal element in direct electrical contact with the signal element, by the mounting elements of the signal contact forcing the substrate against the base, the antenna being a flexible antenna and the substrate being a flexible film substrate. a substrate having first and second surfaces (32, 34), the
