in the 7.36- to 10.0-kme frequency range. The horn antenna is fed by a section of waveguide with inside dimensions that are slightly smaller than the standard X-band waveguide. The waveguide is terminated at one end with a waveguide-to-coaxial adapter which contains a female type N connector. A dielectric cover pre- vents dirt and dust from accumulating in the horn antenna. c. The parabolic reflector provides an in- crease of directivity and gain over that of the horn antenna. Holes in the parabolic reflector decrease its wind resistance. The diameter of these holes and their relative location have been designed to minimize any back radiation. The parabolic reflector contains a bracket for mounting the antenna to a tripod, mast, or other suitable support. Three dielectric sup- porting rods attached to the parabolic reflector support the horn antenna.
