Designed for 3G-SDI and HD-SDI distribution, it provides bulk cable for custom-length video connections, rack wiring, and professional AV projects.\u003c\/p\u003e\n\u003cp\u003eAn 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.\u003c\/p\u003e\n\u003cp\u003eOther lengths available: \u003ca href=\"\/products\/canare-l-4-5chd-75-ohm-super-low-loss-3g-sdi-hd-sdi-digital-video-coax-cable-black-by-the-foot\"\u003eBy the Foot\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eFull-Spool Ordering\u003c\/h2\u003e\n\u003cp\u003eEach order quantity of 1 includes one full 300-meter spool, approximately 984 feet (984.25 feet).
