RG-142 is a high-performance, high-temperature coaxial cable frequently used in military, aerospace, and telecommunications applications. It is particularly valued for its double-shielded construction and its ability to maintain stable electrical properties under extreme thermal stress.

Key Features

  • Double Shielding: Utilizes two layers of silver-plated copper braids, providing superior RF shielding and significantly reducing signal leakage and interference.
  • High Temperature Stability: Equipped with a PTFE (Teflon) dielectric and an FEP jacket, allowing it to operate safely in environments from -55°C to +200°C.
  • Signal Integrity: The silver plating on both the center conductor and the shields ensures excellent conductivity and protects against corrosion.
  • Compact & Tough: With a diameter of approximately 0.195 inches, it offers a high power-to-size ratio and is resistant to chemicals, oils, and lubricants.
