Canare L-4.5CHD 75 Ohm Super Low Loss 3G-SDI / HD-SDI Digital Video Coax Cable (Black, 984'/300m)

The Canare L-4.5CHD is a black, 75-ohm super low loss digital video coaxial cable supplied on a full 300-meter spool, approximately 984 feet. Designed for 3G-SDI and HD-SDI distribution, it provides bulk cable for custom-length video connections, rack wiring, and professional AV projects.

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. Keep a full spool on hand to cut the lengths each equipment layout requires.

Full-Spool Ordering

Each order quantity of 1 includes one full 300-meter spool, approximately 984 feet (984.25 feet). This listing is sold by the spool, not by the foot. Spool length is the total cable supplied, not the supported length of a single SDI run.
