Product Description
Long-Distance 12G-SDI Performance with Full-Size RG6
The AV-Cables Belden 4694R 12G UHD-SDI BNC cable is designed for professional broadcast, live production and commercial AV systems requiring dependable 4K UHD signal transmission over longer cable runs.
Built with genuine Belden 4694R full-size RG6 coaxial cable and professional true 75-ohm BNC connectors, this assembly supports SD-SDI, HD-SDI, 3G-SDI, 6G-SDI and single-link 12G-SDI video.
The larger 18 AWG conductor and lower-loss RG6 construction make 4694R the preferred AV-Cables option when maximum SDI transmission distance is more important than minimizing cable diameter.
Why Choose Belden 4694R RG6?
Belden 4694R combines an 18 AWG solid silvered-copper conductor, gas-injected foam polyethylene insulation and professional foil-and-braid shielding. Its full-size RG6 construction provides lower attenuation than RG59 and Mini RG59 cable for longer professional 12G-SDI runs.
