RG 59 BX 75ohm Coaxial Cable
COAXIAL CABLE) A cable composed of mutually insulated coaxial conductors inside and outside: the inner conductor is copper wire, and the outer conductor is copper pipe or mesh. The electromagnetic field is closed between the inner and outer conductors, so the radiation loss is small, and it is affected by external interference.
The interference effect is small. Commonly used to transmit multiple telephones and televisions.
The name of the coaxial cable is related to its structure. Coaxial cables are also one of the most common transmission media in LANs. The pair of conductors it uses to transmit information is selected according to the structure that a cylindrical outer conductor is set outside the inner conductor (a thin core), and the two conductors are separated from each other by insulating materials. The outer conductor and The center of the central axis is on the same axis, so it is called a coaxial cable. The reason why the coaxial cable is designed like this is to prevent external electromagnetic waves from interfering with the transmission of abnormal signals.
