3G HD SDI Video Evolution 301-299 Flexible Cable Neutrik RearTwist BNC on Drum

3G HD SDI Digital Video Flexible Neutrik BNC Cable on Drum with Stand

Ebay logo

Cable on the main drum can be deployed on location as required and the the tail of the cable on a secondary spool can be accessed (up to 2m) to make a suitable connection. This is a system that I have used on countless live video set-up’s and found it to work very well.
All my cables are custom made by myself using care, experience and the right tools.
Other lengths, cables and plugs, are available, just ask me.
Cable: Evolution 301-299
Evolution 301-299 has a 6.147mm Diameter (same form factor as Belden 1505F which is a more flexible stranded version of Belden 1505 / Argosy Image 720) with a Black PVC outer jacket 
Ideally suited for use on cable drums where repeated deployment is needed.
