Introduction
RG142 Coaxial wire is a high-performance 50-ohm RF wire that is commonly used in military, aerospace, telecom, and industrial communication systems. It is noted for its silver-plated conductors, PTFE dielectric, and double shielding, which make it ideal for high-frequency and high-temperature applications.
RG142 has better thermal resistance and shielding performance than many common RF cables.
What is RG142 Coaxial Cable ?
RG142 is a 50-ohm double-shielded coaxial cable designed for dependable signal transmission in harsh conditions.
It is commonly compared to RG58 coaxial cable, but it has higher temperature resistance and better shielding.
Types of RG142 Coaxial Cables :
RG142 cable is available in a variety of configurations depending on the conductor type and application needs.1. RG142 Standard (Solid Conductor)
- Inner conductor is solid silver-plated copper.
- PTFE dielectric
- Double silver-plated copper braid.
- Suitable for stable RF installations.
2. RG142 Stranded Conductor Variant
- Stranded silver-plated copper conductor.
- More flexible
- For mobile or vibration-prone applications.
3. RG142 High-Temperature Version
- Enhanced PTFE insulation.
- Ideal for aerospace and military.
4. RG142 Custom RF Cable Assemblies
- Terminated with SMA, TNC, N-Type, and BNC connections.
- Utilized in test equipment and communication systems.
