The UHA 9105 is a tunable UHF half-wave dipole that serves as a reference antenna for precise field strength measurements and the generation of defined electromagnetic fields. Thanks to telescopic elements, the dipole length can be flexibly adjusted to the desired frequency range, making the antenna suitable for a wide range of applications in the UHF segment and ideal for professional measurement and test tasks.
