Abstract

207,197. Telefunken Ges. f³r Drahtlose Telegraphie. Nov. 18, 1922, [Convention date]. Wired wireless systems.- High-frequency telegraph and telephone currents are transmitted over the lightning wire a associated with a power wire b, a connecting piece being inserted where the power wire runs underground in a cable c. The high-frequency apparatus d is connected between the lightning wire and earth, and the lightning wire is insulated at the connection point and at the adjacent masts, but is earthed at the other masts.
