Abstract: Systems and methods of use for a radial combiner. The radial combiner is made of a radial cavity defined by a top plate, a bottom plate, an outside wall connecting the top plate and the bottom plate, and an interior of the radial waveguide cavity located between the top plate, the bottom plate, and the outside wall with a substantially uniform height throughout. Inside the radial cavity are multiple monopole radiators, while outside the radial cavity multiple coaxial ports are mounted on one of the top plate or the bottom plate. Each of the coaxial ports are electrically connected to a corresponding monopole radiator inside the cavity. The radial combiner also contains a center conductor which is located in the center of the radial cavity, and transitions to a coaxial waveguide which is exterior to the cavity.

Abstract: An ear shield assembly which attaches to various headgear and protects the users ears against the sun and ultra violet rays, thereby reducing the probability of inducing cancer in this normally sensitive and exposed area. The head gear is typically a cap with the protective ear shield attachments positioned on opposite sides of the cap. These ear shields are placed above the ears and may be folded up against the cap and secured to the side of the cap with hood and loop material when they are not in use. When in use, these shields are lowered and extended outward horizontally from the brim of the cap, allowing air to reach the users ears, while at the same time blocking the sunlight from reaching the ears.
