The leakage current along the feeding cables gives problems to antenna measurements in both the GTEM cell and the anechoic room. The practical and effective solutions to reduce the leakage current are ferrite beads, baluns and reducing cable movements.

ETS-Lindgren's engineers also presented papers on several topics, including an alternative method of computing the free-space antenna factor for site validation of fully anechoic rooms (1) and a new homogenization method that can address situations in which the contrast of material properties is high.
