This paper discusses the effect on the measurement results of the wiring arrangement of an antenna cable with respect to the long wire antenna method specified in CISPR 25 edition 4 Annex J. The experimental results show that the impact on the measurement results still exists even though a setup with multiple ferrites on the cable is used as recommended in Annex J. Measurement results of the Backward Cabling method which positively utilizes the influence of an antenna cable on the measurement system is shown. In addition, the Backside Cabling method which minimizes the influence of an antenna cable on measurement results is proposed. Furthermore, issues related to CISPR 25 edition 4 are considered based on the characteristics of and differences between these two cabling methods.
