RG 500 coaxial cable DESCRIPTIONConductor: 2.77mm copper clad aluminumDielectric: 11.43mm Physical FOAM-PEShield: Al-foil Shielded 100% CoverageBare Copper Braid 60% CoverageJacket: 14.22mm black PEAPPLICATIONThese cables are developed for wideband network systems. They have highest levels of security and flexibility while at the same time lower attenuation values when compared with the customary cables.Electrical Characteristics Impedance 75±2.0 Ohms Capacitance 50±3.0(pF/m) Velocity of Propagation 86% Return Loss(dB) VHF5-300MHz>= 22dB UHF300-960MHz>= 20dB Screening Attenuation(dB) VHF5-50MHz>=100dB UHF200MHz Upward>=110dB Attenuation[@68°F.
