Belden 6339Q8 877U is an RG-6 quad-shield coaxial cable with an 18 AWG solid bare copper conductor and a low smoke PVC jacket for plenum indoor installations. It uses foam FEP insulation and a Duofoil® + aluminum braid + Duofoil® + aluminum braid shield stack for strong EMI protection. Key electrical characteristics include 75 Ohm nominal characteristic impedance, 83% nominal velocity of propagation, and published attenuation values up to 1000 MHz. It is designed for surveillance, CATV, and MATV signal distribution in plenum spaces, is CMP rated, and tested to NFPA 262.
