This cable is ideal for permanent installation use in studio racks and rooms where extended range is required for 12G UHD SDI.
Designed and built to work with the most demanding SDI signals, the new Neutrik BNC plugs are tested to 24GHz and the new Belden cable is made for 12G signals.
All my cables are custom made by myself using care, experience and the right tools.
Cable: Belden 4694R
This cable has been designed and built for Ultra High Definition SDI video signals, from the Belden spec sheet:
12 GHz Coax, 4K UHD Precision Video Cable, RG-6/U Type, 75 Ohm, 18 AWG solid .040" silver plated copper conductor, gas-injected foam HDPE insulation, Duofoil® bonded to core + tinned copper braid shield (95% coverage), CMR, PVC jacket.
The rearTWIST UHD BNC connectors are specifically designed for high resolution video signal transmissions.
Due to the unique insulator and contact pin design, the connectors feature low return loss values for 4K and 8K signals.
Complete range of 10 colour coded rubber cable strain relief caps.
Optional PLIOTEX-Vplus cable identity markers; a colour coded numerical identity system
that is applied to both ends of the cable during manufacture, please let me know what numbers you require.
