Koaksi

Koaksi refers to a specific type of coaxial cable. Coaxial cable is an electrical cable consisting of an inner conductor surrounded by an insulating layer, a conductive shield, and an outer insulating layer. This construction allows it to carry signals at high frequencies with low loss and to be immune to external interference. The term "coaxial" comes from the fact that the inner conductor and the outer shield share the same geometric axis.

There are various types of coaxial cables, distinguished by their impedance, shielding effectiveness, and physical characteristics. The most common impedances are 50 ohms and 75 ohms. 50-ohm cables are typically used in radio frequency applications, such as antenna connections and Ethernet networks. 75-ohm cables are widely used for video transmission, including cable television and satellite TV. The specific type of koaksi would depend on its intended application and technical specifications, such as RG designations (e.g., RG-58 for 50-ohm, RG-6 for 75-ohm). The construction and materials used in koaksi determine its performance and suitability for different environments and signal types.
