Belden 1855A 003, Coax Sub Miniature 23 AWG PE FR PVC Orange

Belden 1855A 003 is a 75 Ohm SDI coax for high-performance digital video, including 6 Gb/s UHDTV and HD-SDI 1080p. This Mini 59 / RG 59 style coax features a 23 AWG solid BC - Bare Copper conductor with PE - Polyethylene (Foam) insulation. Shielding combines Duofoil® tri-laminate tape plus a 95% Tinned Copper braid, and the cable is finished with a PVC - Polyvinyl Chloride jacket in Orange. It supports CMR Riser applications and provides controlled electrical performance through 6000 MHz.
