Investigations with a model surface wave transmission line

This paper summarizes the results of experimental studies conducted with a scale model of a surface wave transmission line (swt line) for long-distance transmission. The purpose of the experiments was to determine the effect of supports, bends, and sags on the transmission loss of such a line. Also, the coupling between parallel identical lines has been measured and compared with the theory. Formulas and other information are given which may be applied to the design of a swt line for long-distance transmission.
