This advanced shielding design maintains the integrity of high-frequency video signals, delivering superior performance required for 4K UHD and professional HD/SDI video applications.
Q: What types of projects or environments are best suited for BELDEN 4855R cable?
A: BELDEN 4855R excels in demanding settings such as broadcast studios, professional A/V installations, and 4K/HD/SDI digital video transmission. Its robust construction and high flexibility make it ideal for both permanent installations and temporary event setups requiring ultra-low attenuation and reliable signal quality.
Q: When should I choose BELDEN 4855R over standard coaxial cables?
A: BELDEN 4855R is recommended when your project requires the highest signal quality over long distances, particularly for 4K UHD or high-definition video. Its ultra-low attenuation and comprehensive shielding ensure minimal signal loss, making it a better choice than standard coax cables for critical broadcast, venue, or production applications.
Q: Where can BELDEN 4855R be installed for optimal performance?
A: This cable performs optimally in indoor environments like broadcast studios, control rooms, performance venues, and professional video production spaces. Its CM flame rating and flexible PVC jacket also make it suitable for concealed or rack-mounted installations in A/V system integrations.
Q: What is the installation process for BELDEN 4855R cable?
A: Installation is straightforward due to its flexible design and manageable 3.7 mm diameter. For best results, maintain a minimum single bend radius of 37 mm during routing. The cable is available on standard 305 meter (1000 ft) reels for continuous runs, compatible with conventional 75-ohm connectors (not included).
Q: How does ultra-low attenuation benefit video transmission quality?
A: Ultra-low attenuation ensures minimal signal loss over distance, preserving the quality and sharpness of high-resolution video signals. For BELDEN 4855R, attenuation is just 5.2 dB per 100 meters at 1 GHz, which is crucial for maintaining 4K UHD and HD/SDI performance during long cable runs in professional installations.
