Product Description
RG179 is a MIL-DTL-17 compliant 75 Ohm RF cable (M17/94-RG179) engineered for video, broadcast, and high-frequency signal transmission where space is limited. Featuring a stranded silver-coated copper-covered steel center conductor and single silver-plated copper braid shield, this compact 2.54mm diameter cable delivers clean signal quality with low attenuation up to 3 GHz. The PTFE dielectric and FEP jacket enable reliable operation from -55°C to +200°C, making it a trusted choice for professional video studios, CCTV installations, and broadcast equipment.
