These plenum grade RG58/U Ethernet cable assemblies are designed for high temperature applications that require flame retardant properties. The 50 Ohm BNC connectors utilize a heat shrink strain relief for a robust assembly. The coaxial cable features double shielding to meet the shielding parameters found in section 10.5 of IEEE 802.3 specification. We stock these assemblies in a wide range of standard lengths from 1 to 100 ft.
