High-Performance Double-Shielded 50-Ohm RG214 Coaxial Cable with Solid Bare Copper Core and Dual Silver-Plated Copper Braids for Broadcast, Military, and Maritime Communication Systems
The Worldpeak RG214 50-Ohm Coaxial Cable is a high-performance, double-shielded RF cable engineered for environments requiring superior electromagnetic isolation and low signal attenuation. Built upon a rugged 10.8 mm architecture, this premium 50-ohm coaxial cable integrates a solid bare copper center conductor and two layers of silver-plated copper braid shielding. Zhenjiang Worldpeak Communication Co., Ltd. manufactures this specialized double-shielded RF cable to deliver over 90 dB of shielding effectiveness, making it the industry standard for multi-transmitter broadcast sites, defense communication hubs, and high-interference aerospace installations where single-shielded cables fail.
The Worldpeak RG214 50-Ohm Coaxial Cable represents the pinnacle of flexible, high-isolation transmission lines. Designed specifically to mitigate radio frequency interference (RFI) and electromagnetic interference (EMI) in dense spectral environments, this silver-plated copper braid cable provides a heavy-duty upgrade to standard single-shielded configurations like the RG213. At the core of the Worldpeak RG214 coaxial cable is a high-purity, 2.26 mm solid bare copper conductor that ensures a highly stable and low-attenuation signal path across wide frequency spectrums.
This 50-ohm coaxial cable utilizes a robust solid polyethylene (PE) dielectric to maintain precise impedance consistency at 50 ohms. The defining engineering achievement of this double-shielded RF cable is its dual-layer shield network. By layering two distinct silver-plated copper braids, Zhenjiang Worldpeak Communication Co., Ltd. creates a mesh-over-mesh geometry with opposing lay directions. This specific construction minimizes microscopic apertures between wire junctions, suppressing RF ingress and egress at frequencies well above 100 MHz. The silver plating on each braid ensures that contact resistance remains exceptionally low over decades of service, preventing the generation of passive intermodulation (PIM) products under high RF power loads.
Advanced Dual-Shield Architecture: Features two separate layers of silver-plated copper braid shielding (>=95% inner and >=90% outer coverage) providing an exceptional shielding effectiveness of greater than 90 dB.
Premium Silver-Plated Braid Cable Construction: The silver plating prevents the formation of insulating copper oxides, ensuring long-term conductivity and stable shield decoupling.
Solid Bare Copper Core: Equipped with a 2.26 mm solid bare copper center conductor that optimizes electrical conductivity and ensures a low-attenuation coaxial cable performance profile.
Superior Environmental Resistance: Outer jacketed in a 10.80 mm UV-resistant PVC or PE compound, allowing reliable operation in extreme weather conditions from -40°C to +80°C.
Mechanical Integrity: The braid-over-braid configuration eliminates the seam-splitting vulnerabilities common in foil-shielded alternatives, making it ideal for high-vibration environments.

The primary engineering justification for selecting the Worldpeak RG214 coaxial cable over standard options lies in its sophisticated material choices. In high-power multi-transmitter installations, standard copper braids oxidize when exposed to atmospheric moisture. Copper oxide acts as an electrical insulator. In a double-shielded configuration without silver plating, copper-to-copper mechanical contact between the two layers would degrade as oxide layers form, effectively decoupling the shields and reducing isolation. Because silver oxide remains highly conductive, the silver-plated copper braid cable maintains a perfectly conductive interface across its lifespan, preserving the vital 90 dB EMI barrier.
Furthermore, the mechanical design of this 50-ohm coaxial cable excels under physical stress. Unlike foil-wrapped cables that can tear or develop gaps along the foil seam during continuous wind loading or tower vibrations, the interwoven braids of the Worldpeak RG214 coaxial cable shift dynamically while maintaining total coverage. This eliminates structural leakage points that would otherwise compromise sensitive receiver systems.
Multi-Transmitter Broadcast Sites: Installed as high-isolation feeder lines on transmission towers where co-located FM and digital TV signals would otherwise bleed into adjacent receiver equipment.
Defense & Military Communication Hubs: Utilized in tactical shelters and base stations to prevent high-power HF or VHF transmitters from blinding sensitive monitoring arrays.
EMC Test Chambers: Deployed inside RF shielded rooms as test instrumentation cabling, ensuring all measured data reflects the device under test rather than cable leakage.
Maritime Multi-Radio Platforms: Integrated into marine vessel masts where radar, satellite, satellite voice, and VHF radios operate in immediate structural proximity.
Zhenjiang Worldpeak Communication Co., Ltd. provides comprehensive commercial support for global engineering firms, system integrators, and distributors. Every shipment of Worldpeak RG214 coaxial cable is accompanied by detailed Certificates of Conformance (CoC), validating adherence to CE, RoHS, FCC, UL94, and ISO9001 standards.
Recognizing that custom lengths and termination quality are critical to preserving a 90 dB shielding rating, Zhenjiang Worldpeak Communication Co., Ltd. offers full OEM customization services. This includes custom jacket branding, specific bulk packaging configurations on rugged wooden reels, and factory-terminated jumper assemblies equipped with heavy-duty N-Type, 7/16 DIN, or 4.3-10 connectors featuring specialized dual-shield crimp ferrules.
Q: Can standard N-type RF connectors be used with the Worldpeak RG214 coaxial cable?
A: No, standard N-type connectors engineered for single-shield options like RG213 cannot accommodate the secondary braid layer of this double-shielded RF cable. You must specify connectors explicitly designed for RG214 coaxial cable containing dual-shield termination crimp ferrules to preserve the 90 dB isolation rating.
Q: Does silver tarnish impact the electrical performance of this 50-ohm coaxial cable?
A: Silver tarnish is a surface sulfide layer that remains fully conductive, meaning it does not reduce the shielding effectiveness of the silver-plated copper braid cable. However, to ensure minimal contact resistance at the connector interface, Zhenjiang Worldpeak Communication Co., Ltd. recommends terminating and deploying the cable within 12 months of production.
Q: What installation modifications are required for a low-attenuation coaxial cable of this weight?
A: Weighing approximately 200 grams per meter, the Worldpeak RG214 coaxial cable requires closer structural support intervals. Cable hangers should be spaced every 1.0 to 1.2 meters on vertical runs to prevent structural stress, compared to the 1.5-meter spacing used for lighter single-shielded lines.
