Know before you buy
Yes, the L-4CFB is specifically engineered for professional broadcast environments. Its low attenuation design ensures signal integrity over longer distances compared to standard coaxial cables.
Absolutely. It features dual shielding, including 100% aluminum foil and a tinned copper braid, which provides excellent noise rejection in environments with high electrical interference.
This cable is rated for 3G-SDI and HD-SDI signals. While it performs exceptionally well for those standards, you should verify your specific 4K hardware requirements, as higher-resolution signals may require different bandwidth specifications.
The solid copper #20 AWG conductor offers superior conductivity and durability compared to stranded alternatives. This ensures a stable, high-quality signal path that is less prone to degradation over time.
Yes, the PVC jacket is designed to be robust and protective. It is well-suited for both permanent studio installations and demanding broadcast setups where the cable needs to withstand daily handling.
Maintaining a consistent 75 Ohm impedance is critical for digital video transmission to prevent signal reflections. This cable’s foam PE dielectric ensures that impedance remains stable throughout the length of the run.
