The Canare 12G-SDI 4K UHD Single-Channel BNC Cable (6') makes possible for sending and receiving 12G-SDI / 4K UHD (2160p) signal over a single coaxial BNC cable. This coax cable has enhanced attenuation characteristics that allow transport of 12G signals at much greater distances than comparable-sized coax. Cables are fully SMPTE ST-2082-1 compliant and hand crafted with Canare L-5.5CUHD cable, and BCP-D55UHD 75-ohm BNC connectors. A superb return loss at 12 GHz of 15 dB, 20 dB @ 6 GHz & 26 dB @ 3 GHz makes these cables perfect for 12G, 6G and 3G systems.
