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.
Key Features
75 Ohm impedance – Optimized for video and broadcast applications requiring matched impedance
Compact 2.54mm diameter – Fits tight spaces in patch panels, equipment racks, and camera connections
Stranded SCCS conductor – Silver plated copper-clad steel provides flexibility and durability for repeated handling
MIL-DTL-17 qualified – M17/94-RG179 for consistent quality and reliability
Broad frequency range – Handles signals up to 3 GHz for HD video and RF applications
PTFE dielectric – Stable electrical performance across -55°C to +200°C
FEP jacket – UV resistant, chemical resistant, and low smoke for indoor and outdoor use
