Product Overview

The LK-7201 Shielding Box is a compact dedicated shielding enclosure for OTA radiated testing, mainly used for OTA performance verification of wireless communication modules and small smart terminal antennas. It features a standard 420 mm × 420 mm × 420 mm cubic internal cavity, with an operating frequency range of 700 MHz–6 GHz and shielding effectiveness of >70 dB. The enclosure supports two opening/closing options: manual door and pneumatic door, meeting both laboratory R&D debugging and automated production line batch testing requirements. The internal space can accommodate products under test, small turntables, test antennas, and positioning fixtures, providing a stable electromagnetic isolation environment for OTA tests including TRP, TIS, and antenna radiation pattern evaluation.
