BNC 75 ohm cable connector. The TWIST UHD BNC disassembled connectors are specifically designed for high resolution video signal transmissions. Thanks to the unique design of the insulator and contact pin, the connectors have low loss values for 4K and 8K signals. The contact pin is 1.07 mm and the shield is 7.36 mm.
To ensure high performance for each cable-connector combination at high frequencies, Neutrik tested common coax cables specifically designed for Ultra High Definition (UHD) transmission. Here is the list: CommScope 5765, Gepco VSD2001, Suhner S05163-02, Suhner S05133-07, Percon VK77.
In particular those optimized for UHD are:
Belden 1694A, Belden 1694ANH, Belden 1694DNH, Belden 4694R, Belden 70082, Belden 70082NH, Belden 70082CH, Bryant SD11, Bryant SD10F, Canare L-4.5CHWS, Canare L-4.5CHD, ClarkWire CD7506, DirectCable 301-330 Evolution XPC, DirectCable 301-361 6-Channel Evolution XPC.
