RG179D Double-Shielded 75Ω Miniature Coaxial Cable

M17/94-RG179 | 75Ω | 3 GHz | Double Braid | 3.00 mm OD | -55°C to +200°C

Maximum Signal Integrity in High-EMI Miniature Environments

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.


Key Features
  • 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.

The Engineering Behind the Double Shield

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.

Applications
  • 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.
