Belden 7794A B59, RG 59 U 3 Coax 20 AWG PE FRPVC Black
Description
Belden 7794A B59 is a digital coax snake cable built as a 3-RG59 bundle for SDI/HDTV digital video distribution, including SMPTE 2081-1 6 Gb/s UHDTV and SMPTE 424M 3 Gb/s HD-SDI 1080p. It uses 20 AWG solid BC - Bare Copper conductors with PE - Polyethylene (Foam) insulation (Gas Injected) and a nominal characteristic impedance of 75 Ohm. Shielding is both, braid over foil, using Tri-Laminate (Alum+Poly+Alum), Duofoil®, 100% plus a Tinned Copper (TC), 95% braid. The cable has PVC - Polyvinyl Chloride inner and outer jackets in Black, with NEC/(UL) compliance: CMR and Fire Rating: Riser.
