12G Ultra HD 4K HD SDI Digital Video Belden 4855R thin cable with Neutrik UHD Rear Twist BNC plugs, Hand made Cable

This cable is ideal for installation use in studio racks and outdoors but is light and flexible enough to use for on camera rigging and patch cables.
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.
I offer five different high performance video cables in a range of lengths and plug colour options, so if you are not sure that this is the right cable for you then perhaps you should check out my eBay shop where you will find cable drums, adaptors and other accessories.
If you are still not sure than please, just ask me, I will help.

Cable: Belden 4855R
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-59 Mini, 75 Ohm, 23 AWG solid .023″ silver plated copper conductor, gas-injected foam HDPE insulation, Duofoil® bonded to the core + tinned copper braid shield (95% coverage), PVC jacket.

Connectors: Neutrik NBNC75BDD6X Rear Twist BNC Plug 
This is the latest high performance connector from Neutrik
With Swiss antraloy plating
The rearTWIST UHD BNC connectors are specifically designed for high resolution video signal transmissions.
