Belden 4855R 12G-SDI 75 Ohm 4K UHD Mini RG-59 Coax Video Cable, Black, 1000-Feet

Belden 4855R 12G-SDI 75 Ohm 4K UHD Mini RG-59 Coax Video Cable, Black, 1000-Feet

Belden 4855R is a 12 GHz, 4K UHD Precision Mini RG-59, 75 Ohm Video Cable. It's 23 AWG and features a solid 0.023 silver-plated copper conductor, gas-injected foamed high-density polyethylene insulation, with Duofoil bonded to the core plus a tinned copper braid shield (95% coverage) in a PVC Jacket.

Belden 4K UHD Coax Cables for 12G-SDI maximize 4K signal transmission distance over a single coax, minimizing weight and space utilization compared to multi-link solutions. This solution provides significant headroom and guarantees -15 dB return loss from 4.5 to 12 GHz.

Key Features

• Faster Installation: Using Belden's single-link solution saves time and is significantly lighter than dual or quad-link configurations
• Optimized Design: On Belden 4K UHD Coax Cables for 12G-SDI, the inner foil is bonded to the core to eliminate bunching when installing
• 1-piece connectors. The outer foil is bonded to the jacket for a quicker, one-step stripping process
• Superior Performance: The 4K UHD coax cable for 12G-SDI are superior in performance and engineered to optimize transmission distance, the cables exceed the SMPTE Return Loss (RL) specifications for UHDTV
• Supports 12 GHz: Belden 4K UHD Coax Cables for 12G-SDI are capable of supporting 12 GHz bandwidth and enable a single-link configuration to transmit 4K
