The LVVL is a fully compliant, calibrated 2 m large loop antenna that complies with standard CISPR-15 / EN55015 section 7.2 and annex B. The calibrated frequency range is 9 kHz to 30 MHz. Each antenna is supplied with antenna factor data. It can be used with any EMC receiver or spectrum analyser. The performance of the loops is matched to the `ideal´loop as shown in EN55015 fig B4 using the prescribed test set-up. The LVVL is a complete 3-axis antenna with a switching unit to select each loop in turn. The loops are 2 metre in diameter with the lowest point 0.5 metres above ground and are fitted with specially designed current transducers in fully screened housings. The main framework is wood with 25 mm diameter plastic tubing for the loops.
