High-temperature, double-shielded RG142 50-Ohm coaxial cable certified by ISO9001, CE, and RoHS. Engineered by Zhenjiang Worldpeak with a solid silver-plated SPCCS core, dual silver-plated braids (>90 dB EMI isolation), and an extruded PTFE dielectric, it delivers exceptional phase stability and thermal resistance from -55°C to +200°C for aerospace, defense, and RF test setups.
The Worldpeak RG142 is a premium high-temperature coaxial cable engineered for critical B2B RF interconnects where thermal extremes and signal degradation cannot be compromised. This high-performance 50-ohm coaxial cable features a solid silver-plated copper-clad steel (SPCCS) conductor, an extruded PTFE dielectric, and dual silver-plated copper braids. Operating reliably from -55°C to +200°C, the Worldpeak RG142PTFE dielectric cable outperforms standard polyethylene cables. This double-shielded RF cable prioritizes mechanical shielding and structural integrity, making it the perfect choice for aerospace, defense communication, and high-frequency industrial environments.
The Worldpeak RG142high-temperature coaxial cable is designed to address the strict demands of modern RF engineering. By utilizing a solid silver-plated copper-clad steel center conductor, this 50-ohm coaxial cable delivers exceptional dimensional stability and tensile strength. The solid conductor design minimizes thermal expansion mismatch, ensuring stable phase performance during rapid temperature changes.
A key engineering element of this PTFE dielectric cable is the extruded polytetrafluoroethylene (PTFE) core. Because PTFE does not flow like standard thermoplastics, Zhenjiang Worldpeak Communication Co., Ltd. utilizes specialized paste extrusion and sintering. Zhenjiang Worldpeak Communication Co., Ltd. tightly monitors sintering temperature and dwell time. This prevents microscopic density fluctuations that cause impedance ripple on time-domain reflectometry (TDR) measurements.
For shielding, this double-shielded RF cable features two layers of tightly woven silver-plated copper braids applied in opposing lay directions. This dual-layer shielding delivers >90 dB of electromagnetic isolation. This protects delicate RF signals from severe external interference in environments dense with transmitters.
Broad Temperature Range: The PTFE dielectric cable construction supports stable operations from -55°C to +200°C, shielding against thermal degradation.
Dual-Layer Shielding: The double-shielded RF cable design achieves >90 dB shielding effectiveness, making it ideal for high-EMI military and aerospace installations.
Robust Signal Integrity: Rated as a premium 50-ohm coaxial cable, the Worldpeak RG142 maintains a strict impedance tolerance of ±2 Ω for minimal signal reflection.
Environmental Resilience: Wrapped in a premium FEP or PTFE outer jacket, the RG142 coaxial cable resists moisture, UV radiation, chemical exposure, and mechanical abrasion.
Optimized Electrical Performance: The silver-plated conductors minimize skin-effect losses, ensuring low attenuation at higher frequencies.

When selecting an RG142 coaxial cable, engineers often evaluate trade-offs against alternative cables:
VS. RG400: While both options are PTFE dielectric cable products, RG400 uses a stranded conductor. The Worldpeak RG142 uses a solid SPCCS core, offering superior phase stability over temperature fluctuations and making it ideal for static runs.
VS. RG223: RG223 offers dual shielding but uses a polyethylene dielectric limited to +85°C. For applications exceeding this thermal ceiling, the high-temperature coaxial cable performance of RG142 is required.
VS. RG58: RG58 is highly flexible but lacks the double-shielding and thermal resilience of the Worldpeak RG142. For high-vibration, high-EMI, or high-temperature areas, RG58 is not a viable substitute.
Aerospace & Avionics: Perfect for unpressurized avionics bays where this double-shielded RF cable prevents signal egress and withstands high altitudes.
Defense & Tactical Communications: Used in military vehicle-mounted transceivers, where the 50-ohm coaxial cable ensures steady communications across fluctuating climates.
Environmental Test Chambers: Serving as internal test leads for RF devices, the high-temperature coaxial cable survives repeated thermal cycles without dielectric drift.
High-Power Broadcast Systems: Ideal for transmitter runs where the RG142 coaxial cable blocks EMI leakage.
Connector Soldering: PTFE requires precise thermal management. Apply a temperature-controlled iron at 350°C for no more than 3 to 4 seconds to prevent phase changes at the connector interface.
Tarnish Management: The silver-plated braids may develop a surface sulfide layer. Zhenjiang Worldpeak Communication Co., Ltd. recommends nitrogen-purged packaging for long-term storage to prevent tarnish.
Bend Radius Limits: The solid conductor of this RG142 coaxial cable can suffer from flex fatigue if repeatedly bent. Ensure a minimum static bend radius of 25 mm during routing.
Zhenjiang Worldpeak Communication Co., Ltd. manufactures the Worldpeak RG142 in an ISO9001-certified facility. By sourcing this high-temperature coaxial cable directly from the manufacturer, B2B buyers access unmatched pricing and strict quality control.
Zhenjiang Worldpeak Communication Co., Ltd. provides full Certificates of Conformance (CoC) with every shipment. To streamline your assembly process, the company offers custom jacket marking and factory-terminated jumper assemblies equipped with matched SMA, N-Type, TNC, or BNC connectors.
Q: Why choose a PTFE dielectric cable over a PE dielectric cable?
A: PTFE remains electrically stable up to +200°C, whereas PE softens and deforms above +85°C. For phase-sensitive and high-temperature environments, PTFE prevents impedance drift.
Q: Does Zhenjiang Worldpeak Communication Co., Ltd. supply matched connectors for the Worldpeak RG142?
A: Yes. Zhenjiang Worldpeak Communication Co., Ltd. manufactures silver-plated and gold-plated SMA, N-Type, TNC, and BNC connectors matched to the dimensions of this 50-ohm coaxial cable.
Q: Can this double-shielded RF cable be used in continuous-flex applications?
A: Due to its solid center conductor, the RG142 coaxial cable is designed for static or semi-rigid installations. For highly flexible applications, RG400 should be evaluated.
