Advanced RF shield boxes and test enclosures built for reliable wireless testing.
An RF Shielded Chamber blocks external electromagnetic interference using a continuous metal enclosure, but it does not automatically control reflections inside the chamber. An RF Anechoic Chamber combines electromagnetic shielding with RF absorber materials to reduce internal reflections and create a more controlled testing environment.
If you are performing conducted testing or need an interference-free environment for wireless device development, an RF shielded chamber may be sufficient. For radiated emissions, antenna measurements, OTA testing, or advanced EMC testing, an anechoic chamber may be more appropriate.
This guide explains the difference between these chamber types, where a Semi-Anechoic Chamber fits in, and how to choose the right solution for your testing requirements.
An RF Shielded Chamber is a Faraday-cage enclosure designed to prevent unwanted electromagnetic signals from entering or leaving the test environment. Conductive shielding, RF gaskets, filtered feedthroughs, and shielded ventilation systems help create a controlled testing space.
However, shielding alone does not necessarily eliminate internal RF reflections. Signals can reflect from conductive surfaces inside the chamber, potentially creating multipath effects and standing waves.
RF shielded chambers are commonly used for wireless device development, R&D, quality assurance, conducted testing, and applications where isolation from external RF interference is the primary requirement.
LabiFix provides RF Shielded Chambers designed for wireless testing, OTA applications, antenna measurements, and other RF testing requirements.
An RF Anechoic Chamber combines electromagnetic shielding with RF absorbing materials. These absorbers reduce reflected RF energy inside the chamber and help create an environment that more closely resembles free-space conditions.

- A shielded chamber blocks external RF; an anechoic chamber also absorbs internal reflections.
- Shielded chambers suit conducted tests and DUT isolation; anechoic chambers suit radiated emissions, antenna patterns and OTA.
- Absorber lining adds the largest share of anechoic chamber cost.
