HyperLOG 20300 EMI


Perfect EMC Hybridantenna for the pro user. Unmatched high accuracy. Very high gain over the full frequency range. Latest design and technology.


The HyperLOG 20300 EMI is Aaronia's latest antenna development and combines the advantages of a biconical antenna and those of a log periodic antenna in a single high end EMC/EMI antenna. Furthermore the HyperLOG EMI series offer an extremely high accuracy of 0.3 dB over the full specified frequency range and therefore can even be used as reference antenna.

By using the HyperLOG EMI antennas, the common EMI and EMC measurement error-rates, which show up by switching between different test antennas, are avoided. This is because you have only to use one antenna for the complete frequency range instead of two or more antennas. This saves significant cost since the measuring time is reduced drastically.

The HyperLOG EMI series can also be used as a powerful broadcasting antenna with up to 310 watts. These antennas are suitable even for immunity measurements, where very high field strengths are needed by more than 10 V/m.


Every HyperLOG Hybridantenna goes through rigorous testing in our laboratories before dispatch and is equipped with a high quality rubber paint which offers protection against mechanical damage and environmental influence.


Made in Germany:

All Aaronia antennas are developed, individually produced and calibrated in Germany at the Aaronia factory. This guarantees highest standard so that Aaronia can offer every customer a full 10 years warranty for all EMC/EMI antennas.


Exhaustive Calibration data:

All Aaronia Hybridantennas include a complete high resolution calibration data set with an unmatched number of calibration points. This offers the ability to make a very accurate EMC measurement with any Spectrum Analyzer.



All HyperLOG EMC/EMI antennas can be equipped with various options which highly expand the functionality. More details about possible options are available at above section "Options".
