RG58 Coax Cable

RG58 Coaxial Cable is a flexible and lightweight coaxial cable with a 50-ohm characteristic impedance and maximum voltage rating of 1,900 volts. The central conductor is 20 American Wire Gauge pure annealed copper, although some versions may use a stranded tinned copper conductor. The outside diameter of the cable is 0.195 inches (4.95 mm), which makes it suitable for indoor and vehicular use where size matters. It is best for signal frequencies up to 1GHz, where its attenuation is 14.5 decibels per 100 feet. Above that frequency, attenuation increases, and at 5GHz it is approximately 60 dB/100 ft. RG58 coaxial cable supports 10Base2 Ethernet.
