This RG59 Coaxial Cable (75 Ohm) is a high-quality, industry-standard cable designed for video, RF, and broadcast applications.
Constructed with a solid copper-clad steel (CCS) inner conductor, solid PE dielectric, and 80% copper braid shielding, this cable provides stable signal transmission with effective interference protection.
With a 6.15mm external diameter and durable black PVC jacket, it is ideal for fixed installations, CCTV systems, RF distribution, and SDI video runs up to 1GHz.
Available per metre or as a 100m (328ft) reel, making it suitable for both small jobs and full installations.
