The bottom line: this cable is for technicians and video professionals who need a compact, low-loss 6G-capable coax for 1080P and 4K workflows; its main selling point is the Belden 1855A miniature construction that delivers a 6 GHz sweep in a lightweight, low-bend-radius form factor while preserving strong signal performance.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelden 1855A construction:\u003c\/strong\u003e provides a miniature 23 AWG coax with a low loss foam dielectric for reduced attenuation over the run, keeping images clean at higher bandwidths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6G \/ 3G bandwidth support:\u003c\/strong\u003e conforms to SMPTE 2081-1 and SMPTE 424M so it can carry 3 Gb\/s HD and 6 Gb\/s UHDTV signals for 1080P and 4K workflows when used appropriately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble shielded design:\u003c\/strong\u003e the double shield reduces interference and helps maintain consistent SDI performance in noisy environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKings True 75 ohm BNC connectors:\u003c\/strong\u003e crimp-style connectors with heat shrink offer a tidy finish and are covered by a lifetime connector replacement warranty for long-term reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearly marked and organized:\u003c\/strong\u003e cables are length marked and shipped with hook-and-loop straps for straightforward deployment and inventory control on set.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis cable is aimed at broadcast engineers, live-event technicians, and video production crews who need a compact coax that handles HD and UHD signal rates without the weight or bulk of larger coax.
