Canare L-3CFW RG59 HD-SDI Coaxial RF Cable 50ft Male BNC Black

Professional HD-SDI interconnect

Canare L-3CFW RG59 coaxial cable delivers broadcast-grade serial digital video up to 3.0 Gb/s over 50 ft. Male BNC connectors on both ends provide secure locking for studio cameras, switchers and recorders. The assembly meets SMPTE 259M, 292M and 424M-B specifications for SD, HD and 3G-SDI workflows. Black jacket suits permanent rack installs or mobile production kits.

Upgrade from generic RG59 patch leads

Standard consumer coax often lacks the controlled impedance and shielding density required for error-free 3G-SDI transport. This cable replaces thinner runs that exhibit bit errors or clock jitter on long SDI paths. The jump is worth it when signal integrity must survive multiple patch-panel hops or outdoor OB van routing. It does not suit installations needing fibre distance or multi-channel MADI over coax.

Sustained load behaviour

Dense braid plus foil shielding maintains consistent return loss and attenuation across the full 50 ft during continuous 3 Gb/s carriage. Conductor geometry stays stable under repeated flexing in live-event deployments. Connectors retain mating force after hundreds of insertions, preventing intermittent contact during extended recording sessions. No active equalisation is required at the receiver for this length at 3G rates.
