Triple Loop Antenna

Triple Loop Antenna for CISPR 15 / CISPR 16-1-4

The ALT-930-2M is a Triple large loop antenna system (LAS) based on the Van Veen/ Bergervoet principle. The operating frequency is from 9kHz to 30 MHz. The loops are 2m in diameter with the lowest point 0.5m above ground. The loop support structure is very easy to erect and with its wheel base very convenient to move. It is a complete 3-axis antenna system with three loops and three current transformers and a remote antenna switch (RAS-930). Each loop is connected to the remote antenna switch via its current transformer. The output of the switch can be connected to any EMI measurement device. The performance of each loop (including current transformer) is matched to the ‘ideal’ loop curves as shown in CISPR 16-1-4 & CISPR 15 using the prescribed test set-up. Calibration data and certificate is provided with each antenna system. A calibration balun dipole loop and EUT support can be also procured optionally.
