The UHA 9125 D is a low-loss, linearly polarized half-wave dipole with EMI balun for applications in the upper GHz range. It serves as a precise reference antenna for generating defined radiated power and for field strength measurements. Thanks to interchangeable elements, it can be adapted to different center frequencies and offers almost ideal radiation characteristics with high symmetry.
