Abstract
The paper analyzes the scattering characteristics of VHF/UHF television broadcasting waves which are obliquely incident on finite length multibundle conductors of overhead power transmission lines. Numerical calculations were made for four-bundle conductors currently employed in Japan; the attenuation, directivity, and frequency characteristics were clarified. To verify the theoretical results, 1:40 scale (for VHF) and 1:10 scale for (UHF) model experiments have been carried out. Agreement between the theoretical results and the measurements was reasonably good.
