M17/94-RG179 | 75Ω | 3 GHz | Double Braid | 3.00 mm OD | -55°C to +200°C
In the world of miniature electronic devices, electromagnetic interference (EMI) is the invisible enemy. As medical endoscopes, UAV video links, and high-density test instruments pack more electronics into smaller spaces, single-shielded cables often act like antennas, picking up noise from motors, switching power supplies, and high-speed data lines. The RG179D is engineered to solve this exact problem. It takes the proven 75Ω, 3 GHz electrical core and encases it in a dual-layer silver-plated copper braid (2:SC). This interlocking, opposite-direction double shield creates a near-perfect miniature Faraday cage, drastically reducing transfer impedance and blocking external EMI/RFI. With an outer diameter of just 3.00 mm and a low capacitance of 64 pF/m, the RG179D delivers pristine video and RF signal fidelity without compromising on flexibility or high-temperature performance. It is the ultimate 75Ω signal guardian for spaces where standard cables fail.
Double Silver-Plated Copper Braid (2:SC) – Interlocking dual-layer shield for maximum EMI/RFI rejection and low transfer impedance.
True 75Ω Precision – Matches broadcast, video, and specialized 75Ω systems to ensure low VSWR.
3 GHz Maximum Frequency – Covers UHF, video, SDR, and low microwave applications.
Low Capacitance: 64 pF/m – Preserves fast signal edges and minimizes video distortion.
3.00 mm Compact Outer Diameter – Fits into dense, space-constrained devices.
12 mm Minimum Bend Radius – Maintains excellent flexibility despite the double shield.
FEP Jacket – Resistant to chemicals, oils, and continuous operation up to 200°C.
Stranded Conductor (7/0.10 SCCS) – High tensile strength and flex fatigue resistance.
MIL-DTL-17 Qualified – M17/94-RG179 reliability for defense, aerospace, and medical systems.
RoHS Compliant – Environmentally responsible materials.
| Layer | Material | Diameter (mm) |
|---|---|---|
| 1. Inner Conductor | Silver-Plated Copper Clad Steel, Stranded (7/0.10) | 0.30 |
| 2. Dielectric | PTFE | 1.60 |
| 3. Outer Conductor | Double Braid of Silver-Plated Copper Wire (2:SC) | 2.50 |
| 4. Jacket | Extruded FEP | 3.00 |
The RG179D does not just add a second layer of copper; it engineers a barrier. The two braids are applied in opposite directions, ensuring that the gaps in the first braid are covered by the wires of the second. This interlocking mesh provides nearly 100% physical coverage and vastly lowers transfer impedance. The result is a miniature cable that protects weak signals from external noise and prevents internal signals from leaking out.

Note: Electrical attenuation is determined by the inner conductor and dielectric. The addition of the second braid does not increase loss; it ensures the signal arrives cleanly.
Medical Endoscopes & Probes – Double shielding prevents interference from internal motors and processors, ensuring clear 75Ω video feeds.
UAV & Drone Video Links – Protects high-frequency analog or digital video from engine noise and external RF interference.
High-EMI Test Instruments – Ideal for internal 75Ω wiring where cables are bundled tightly and crosstalk is a risk.
Miniature SDR Receivers – Shields extremely weak incoming signals from local digital noise.
Aerospace Avionics – FEP jacket and 200°C rating support high-altitude and high-temperature environments.
Broadcast & Surveillance – Reliable video transmission in dense, noisy equipment racks.
