Teseq TEM Horn | For IEC 61000-4-39
The Teseq TEM Horn is a horn antenna that generates homogeneous fields in the large frequency range from 600 MHz to 6 GHz. The TEM Horn is specifically designed to achieve IEC/EN 61000-4-39 which describes test methods unique to the situation in which the transmitter is used in close proximity to the EUT. The TEM Horn’s mounting fixture allows easy adjustment for vertical and horizontal polarizations, and has a standard camera thread (1/4” X 20) hole that allows fitting to many support structures including all Teseq tripods. TEM Horn units have two optional matching network adapters that allow an extended frequency range for the TETRA 400 and GMRS 460/FRS 460 applications.
