RG-58

RG-58 is a type of coaxial cable used to transmit radio frequency signals, commonly in computer networks, radio, and television systems. It consists of a central copper wire for signal transmission, surrounded by a layer of insulation, then a metallic shield that protects against interference, and finally an outer plastic cover for durability. Its characteristic impedance is about 50 ohms, making it suitable for certain communication applications. RG-58 is known for being flexible and relatively inexpensive, but it has a limited bandwidth compared to newer cables, making it suitable for short to medium-length connections at moderate frequencies.
