Abstract (en)
[Problem] To provide a coaxial cable which is able to shut off external noises and transmit clear images having no picture disturbance by noises without employing cable compensators over a long distance. [Means for Solution] A first conductor is provided on the outer circumference of a central conductor with an insulator therebetween, a second conductor is provided on the concentric circle having central conductor as its center and outside the first conductor with an insulator therebetween, a coaxial cable formed by coating the outside of the second conductor which is on the concentric circle having the central conductor as its center by insulating external coating is provided, a DC voltage source which is able to apply DC voltage having a predetermined voltage value between the first conductor and the second conductor such that the direct current flowing in the first conductor and the second conductor takes a desired value is provided, and a noise barrier zone formed by the electro-magnetic action of the desired current is formed in the part surrounded by the first conductor and the second conductor on the outer circumference of the central conductor.
