RG142 Coaxial Cable (50 Ohm, PTFE, Silver-Plated, FEP Jacket) | RG142 B/U

Price/m

RG142 is a rugged 50 ohm coaxial cable designed for demanding RF use where temperature tolerance, mechanical durability, and stable long-term performance matter. With a silver-plated copper center conductor, double silver-plated braid, PTFE dielectric, and FEP jacket, it is a strong choice for high-temperature patch leads, compact interconnects, test setups, and robust indoor or outdoor cable assemblies.

Why RG142 Is Popular

• Silver-plated conductors help maintain stable attenuation over time
• PTFE dielectric supports high-temperature operation
• Double braid construction offers strong shielding performance
• FEP jacket adds durability and chemical resistance
• Compact size and good flexibility make it practical for patch leads and dense installations

Typical Applications

• Short RF patch leads for HF, VHF, and UHF systems
• Test bench and lab interconnects
• Amplifier and filter internal wiring
• Portable, tactical, or harsh-environment assemblies
• High-temperature cable runs where standard PVC coax is less suitable

Practical Notes

RG142 is chosen more for robustness, shielding, and high-temperature capability than for lowest possible loss. It is especially attractive for shorter runs, compact assemblies, and connectorized RF jumpers where PTFE/FEP construction and mechanical reliability are more important than absolute feedline efficiency.

For long feedlines, larger low-loss cable is often the better choice. RG142 shines most in shorter interconnects, high-temperature environments, and mechanically demanding assemblies.
