UHF DTV Antenna System diagnostics by radiation pattern measuring

The article deals with the new Large Antenna System (AS) diagnostics method at VHF / UHF range in the air during scattering from the AS. This method is based on comparing the calculated radiation pattern of AS, as an array of unified segments, in the fully functional state with the calculated radiation pattern of AS generated in a state of malfunction caused by faulty segments. Based on results, it is possible to determine a faulty segment by doing a single measurement of the horizontal radiation pattern of AS.
