The results of a log-periodic antennamatching with the feeder lineover the entire operating frequency rangeare presented in this work. The comparison of model and natural experiments results SWR determination in feeder line was carried out. It confirmthe adequacy of the previously proposed methodology for amplitude and phase distributions of the terminal currentscalculating.
