Characteristics Impedance and Attenuation of Transmission Line at Frequencies of 30 and 40 mcs
Abstract
As a matter of comparison and for information, two twisted cable transmission lines of different construction and composition than that of the submitted line were also measured. One of these cables is that as supplied by the General Electric Company with their all wave, noise reducing antenna system. The other cable is standard commercial type twisted lamp cord. All three types of cables were measured for impedance at both 30 and 40 mcs., and for attenuation at 40 mcs. The capacity, inductance and power factor were measured at a frequency of 1000 cycles. The attenuation of the Forest Service transmission line was also measured at 40 mcs with the outer rubber covering removed.
