Outdoor video runs fail when cables crack, lose signal, or degrade under UV and repeated flexing. Broadcast trucks, stadium rigs, and remote CCTV sites all face the same problem — standard coax won’t survive constant bending, rain, or sun exposure. Signal dropouts and re-cabling drive up cost and downtime.The Canare L3CFW is a 75Ω flexible coaxial cable built specifically for outdoor video signal transmission. It uses a 75-3 (3C-2V) construction with stranded center conductor, foam PE dielectric, and a dual-layer shield — aluminum foil plus tinned copper braid. The outer jacket is black polyethylene (PE), rated for direct burial and aerial use. Designed and manufactured by Canare in Japan, it meets the mechanical and electrical demands of professional video, broadcast, and security installations where cable flex, weather, and signal integrity matter every day.Core Specifications

Why the L3CFW Holds Up Where Standard Coax Doesn’t
- Repeated flex without signal loss. The stranded conductor and foam PE dielectric absorb mechanical stress. Tested to withstand continuous flex cycles at 25 mm bend radius — critical for broadcast truck interiors, pan-tilt camera mounts, and portable rigs where cables move daily.
- Outdoor durability, not just outdoor labeling. The PE jacket resists UV cracking, water absorption, and abrasion. Suitable for direct burial, conduit runs, and aerial drop without additional armoring. Maintains impedance and shielding performance after prolonged sun and rain exposure.
- Consistent 75Ω impedance across temperature swings. Foam PE dielectric stays dimensionally stable from -20°C to +60°C. No impedance drift means no reflections or ghosting in HD-SDI, analog composite, or component video signals — even in desert heat or winter outdoor shoots.
- Dual-layer shield blocks EMI in electrically noisy environments. The foil + braid combination provides ≥85% coverage. Works reliably near VFD motors, generators, LED lighting rigs, and RF transmitters common at live event venues and industrial CCTV sites.
