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

 

4855R BDD6x Poster

 

This  cable is ideal for installation use in studio racks and outdoors.
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.
Red Weapon/Helium/Epic/Scarlet/Raven, Arri Alexa/Amira, Sony F5/F55, Panasonic Varicam LT, BMD, BlackMagic Design Ursa/Ursa mini Video Assist 4K etc.
 
All my cables are custom made by myself using care, experience and the right tools. Precision cable stripping and cutting are essential for 3G, 6G and 12G terminations so all of my cables are stripped and cut using a CNC cable lathe made in Switzerland by Schleuniger.
For longer lengths, please see my other listings or just ask me.
