The radiating spherical dipole provides a reliable, electrically isolated, and most importantly - repeatable and accurate signal test source for technical applications. The spherical dipole is comprised of two hemispheres, which form the radiation element of a spherical dipole antenna. The spherical dipole design is based on that used with our Precision Spherical Dipole Source (PSDS) product, and has the same fundamental values as an isolated RF radiating source. Both Spherical Dipoles are interchangable and operate with the same Battery Boards.
