VVLA-30M Triple Loop Antenna (Van Veen Three Loop Antenna)

The VVLA-30M Triple Loop Antenna (Van Veen Three Loop Antenna) is engineered for magnetic field radiated interference testing across the 9kHz to 30MHz frequency range. This antenna incorporates a 50Ω/BNC universal interface, ensuring compatibility with LISUN EMI-9K series EMI receivers as well as other mainstream EMI test receivers meeting equivalent specifications.

This product features a tool-free quick-assembly structure that facilitates straightforward installation and calibration procedures. A height-adjustable, expandable test platform with a 50kg maximum load capacity is included as standard equipment, eliminating the requirement for additional test tables. The orthogonal X/Y/Z three-axis design enables comprehensive angular testing without physical repositioning, thereby minimizing displacement-induced measurement errors.

Each unit undergoes professional calibration prior to shipment, and the antenna integrates a self-calibration mechanism for ongoing verification. This antenna is specifically designed for EMC compliance testing of electrical lighting equipment and similar apparatus according to international standards. The VVLA-30M is recommended for deployment within LISUN SDR-5000B RF shielding rooms or AC-3M semi-anechoic chambers.
