Performance of Sectionalized Broadcasting Towers

With a sectionalized tower high angle radiation can be minimized to give better ground wave performance than is possible with a simple vertical radiator. A study of theoretical conditions in conjunction with physical limitations reveals that it is necessary to maximize the current distribution on any given tower construction to obtain the maximum ground plane field intensity. Several sectionalized towers and a variety of current distributions on each tower are treated theoretically and tested experimentally. The results obtained are compared with the findings of several other writers treating similar problems.
