RG 58 cables C/U,Solid PE Insulated Cable, 4.95mmOD, 50ohm

RF cables RG-58 is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω.  There are several versions covering the differences in core material (solid or braided wire) and shield (70% to 95% coverage). Most two-way radio communication systems, such as marine, CB radio, amateur, police, fire, WLAN antennas etc., are designed to work with a 50 Ω cable. RG58 cable is often used as a generic carrier of signals in laboratories, combined with BNC connectors that are common on test and measurement equipment such as oscilloscopes.
RG-58 cable can be used for moderately high frequencies.
