TEM Horn for IEC / EN 61000-4-39

TEM hornzoom
  • TEM horn for IEC / EN 61000-4-39
  • One TEM horn for the frequency range
    600 MHz to 6 GHz
  • Extendable with matching networks for the TETRA 400 and GMRS 460 / FRS 460 applications
  • High efficiency

The basic EMC publication IEC / EN 61000-4-39 „Electromagnetic Compatibility (EMC) - Part 4-39: Testing and measurement techniques - Radiated fields in close proximity - Immunity test” describes test methods unique to the situation in which the transmitter is used in close proximity to the EUT. The Teseq TEM horn generates homogeneous fields in the large frequency range from 600 MHz to 6 GHz. Two optional available matching network adapters allow to extend the frequency range for the TETRA 400 and GMRS 460 / FRS 460 applications. Using the adapters means one TEM horn for all the bands.
The mounting fixture allows easy adjustment for vertical, horizontal polarizations, and has a standard camera thread (1/4” X 20) hole that allows fitting to many support structures including all Teseq tripods (note Teseq adapters may be required). The combination TEM horn with dipole tube BAA 6001 is recommended for mounting the TEM horn to ∅ 22 mm mast / tripod holder.
