The HyperLOG 20300 and 20600 EMI antennas represent the ultimate EMC/EMI pre-compliance test antennas, featuring unmatched ultra-high accuracy and very high gain over the full frequency range. The 20300 has a range up to 3GHz and the 20600 meets the latest EMI/EMC standards up to 6GHz.The antennas combine the advantages of a biconical antenna and those of a log periodic antenna in a single high end EMC/EMI antenna. They offer an extremely high accuracy of 0.3 dB over the full specified frequency range and therefore can even be used as reference antenna.
