SIEPEL designs, manufactures and installs anechoic chambers for Electromagnetic Compatibility (EMC) and microwave tests or antenna measurements.

Components: shielding elements, doors, electromagnetic absorbers, etc. are manufactured in our premises in La Trinité-Sur-Mer, France.


These structures are designed in accordance with CISPR, EN, MIL-STD, and DO 160 standards.

Several models of semi or full anechoic chambers enable to answer your needs:

  • For pre-compliance or compliance tests, according to commercial and defense standards
  • For High Intensity Radiated Field tests (HIRF)


For EMC, we have local skills and support our local sales partner in the definition and supply of associated instruments.

Dedicated to Radio / Telecom and radar tests, several models are available depending on the antenna to be tested and the measurements environment:

  • Near field antenna measurements chambers for which we can integrate scanners, positioners and instrumentation for cylindrical, spherical, or planar systems.
  • Far field antenna measurements chambers
  • Chambers for antenna measurements in compact ranges
  • Chambers for measurements in Radar Cross Section (RCS)
  • Chambers for tests in RF Hardware in the Loop simulated situation: we integrate target simulation systems, and flight simulators from third-party providers


On this market, SIEPEL is a provider of turnkey solutions and offers test equipment manufactured by NSI-MI. This dual expertise has allowed us to carry out large-scale projects by providing huge chambers suitable for testing aircraft, satellites, or even helicopters.
