RG141 Coaxial Cable M17/71 50 Ohm MIL-DTL-17 Compliant RF Cable with Fiberglass Jacket
RG141 is a MIL-DTL-17 compliant 50 Ohm flexible coaxial cable (M17/71-RG141) built for high-frequency applications requiring mechanical durability and stable electrical performance. It features a solid silver plated copper-clad steel center conductor, PTFE insulation, and a single silver-plated copper braid protected by a fiber glass braid jacket. With a temperature range of -55°C to +250°C and frequency capability up to 8 GHz, RG141 is widely used in communications, radar, and aerospace systems where reliability under physical stress is essential.
- 250°C temperature rating – Withstands higher heat than standard PTFE cables, ideal for engine compartments and industrial ovens
- Fiber glass braid jacket – Adds abrasion resistance and mechanical protection without sacrificing flexibility
- Solid SCCS conductor – Silver-coated copper-covered steel provides strength and stable signal transmission
- 8 GHz frequency capability – Handles demanding RF and microwave applications
- MIL-DTL-17 qualified – M17/71-RG141 for mission-critical reliability
- Low attenuation – Clean signal delivery from 100 MHz to 3 GHz and beyond
- 1900V voltage rating – Suitable for moderate power requirements
