Canare L-4.5CHD 75 Ohm Super Low Loss 3G-SDI / HD-SDI Digital Video Coax Cable (Black, By the Foot)

The Canare L-4.5CHD is a black, 75-ohm super low loss digital video coaxial cable designed for 3G-SDI and HD-SDI distribution. Sold by the foot, it lets you order the cable you need for custom-length video connections, rack wiring, and professional AV projects without purchasing a full spool.

An 18 AWG solid center conductor and highly foamed PE insulation provide the cable's low-attenuation construction. Multi-layer insulation uses different foaming ratios to balance low loss with strength, while aluminum foil and a high-density tinned copper braid help shield the video signal from interference. Measure your runs and cut cable to suit your equipment layout.
