Belden 7788A B59, Coax Bundled Miniature 4C 23 AWG PVC Black Matte
Description
Belden 7788A B59 is a digital coax snake cable featuring a 4-coax bundled miniature design for 75 Ohm video distribution. It is built with 23 AWG solid bare copper conductors, gas-injected foam HDPE insulation, and a Duofoil® tape plus 95% tinned copper braid shield. Designed for riser applications (CMR), it supports SMPTE 2081-1 6 Gb/s UHDTV and SMPTE 424M 3 Gb/s HD-SDI 1080p. It includes a PVC inner jacket and overall PVC outer jacket in a black matte finish for indoor use and outdoor use in black only.
