Hello
Does anyone know where I can find technical data showing a RG6 dual Shield cable can support 4K signals from a camera? Its an SDI connection on the camera

Important for this application is the center conductor. Is it Copper Clad Steel (CCS) or is it solid copper?
Dual shield has a further clarification needed. What % of braid is used on the dual shield?
Dielectric - What is the rated frequency of the coax?
Last is distance. How far has the signal got to go?
If you are using a solid copper center, 60%+ braid w/foil, swept test to 2GHz, and going less than 100 meters (330ft.). Then you should be fine.
[edit]: The ends! Make sure you are using quality compression fitted BNC connectors. If you are using F to BNC adapters, you might have problems. If you are using twist-on BNC connectors, you need to be shot!

It is the Sony BRC-X1000 cameras and as I understand the RG6 cable supports the SDI connection however, We need 2 RG6 cables for 4K.
