High-performance, ultra-flexible RG58 50-Ohm coaxial cable certified by ISO9001, CE, and RoHS. Engineered by Zhenjiang Worldpeak with a 19-strand tinned copper core and a >=90% tinned braid shield, this highly durable 5.0 mm cable ensures stable, low-attenuation signal routing with a tight 25 mm bend radius for test labs, vehicular communications, and wireless networks.
The Worldpeak RG58 is a premium, highly flexible coaxial cable designed for reliable 50-ohm RF connectivity. Engineered by Zhenjiang Worldpeak Communication Co., Ltd., this high-performance RG58 coaxial cable features a nominal outer diameter of 5.0 mm, making it exceptionally lightweight and easy to route compared to bulkier options like RG8. Utilizing a durable stranded copper RG58 core, this 50-ohm coaxial cable balances tight bend-radius flexibility with stable electrical performance. It serves as an ideal short-range interconnect solution for modern telecommunication systems, test laboratories, and vehicular installations worldwide.
The design architecture of the Worldpeak RG58flexible coaxial cable prioritizes physical flexibility and ease of installation over long-distance propagation. The stranded copper RG58 center conductor combined with a solid polyethylene dielectric allows engineers to achieve tight bends in restricted spaces such as equipment racks, broadcast vehicles, and industrial enclosures.
However, system designers must note the inherent attenuation trade-offs. The RG58 coaxial cable is optimized for run lengths under 10 meters at Ultra High Frequency (UHF). For longer distances, attenuation increases, meaning a larger 50-ohm coaxial cable like RG8 or LMR400 should be specified. As an experienced RF coaxial cable manufacturer, Zhenjiang Worldpeak Communication Co., Ltd. ensures that every batch of Worldpeak RG58 meets strict manufacturing tolerances. This guarantees that your RF signal transmission remains stable and shielded from electromagnetic interference (EMI) in dense signal environments.
Selecting the right 50-ohm coaxial cable requires looking at specific structural benefits. The Worldpeak RG58 offers several key advantages:
High-Flexibility Stranded Core: The 19 x 0.18 mm stranded copper RG58 conductor ensures maximum bend recovery and prevents center conductor breakage in high-vibration applications.
Excellent Shielding Effectiveness: Featuring a tinned copper braid shielding with >=90% coverage, this flexible coaxial cable significantly reduces signal leakage and blocks external EMI.
Accurate Impedance Matching: Real-time diameter monitoring on the extrusion line ensures a highly consistent 50-ohm characteristic impedance.
Industrial-Grade PVC Jacket: The 5.0 mm outer diameter is protected by a flexible PVC jacket, providing robust environmental resistance for indoor and protected outdoor systems.

Maintaining absolute batch consistency in a flexible coaxial cable production environment requires strict quality control. Zhenjiang Worldpeak Communication Co., Ltd. addresses this through advanced manufacturing automation:
Active Dielectric Diameter Monitoring: During extrusion, Worldpeak utilizes continuous, real-time laser monitoring to maintain the 3.00 mm solid PE thickness. Minor deviations in dielectric diameter shift the capacitance per unit length, altering the 50-ohm coaxial cable impedance and causing harmful signal reflections.
Precision Stranding Control: The 19-strand tinned copper conductor is wound with a highly controlled lay length. Proper stranding prevents the stranded copper RG58 from developing structural fatigue or micro-fractures during repeated movement.
High-Density Braiding Verification: By ensuring the tinned copper shielding coverage remains at or above 90%, Worldpeak guarantees that this RG58 coaxial cable delivers robust shielding performance, protecting your systems from crosstalk in multi-channel rack applications.
The unique properties of the Worldpeak RG58 make it the preferred 50-ohm coaxial cable across multiple industries:
Test & Measurement Labs: Used extensively for short BNC or SMA test leads connecting signal generators, oscilloscopes, and spectrum analyzers.
Vehicular Communications: Acts as highly durable antenna feedlines for public safety, commercial transport, and amateur radio systems where a flexible coaxial cable is required.
Wireless Infrastructure: Perfect for short jumper assemblies connecting BNC security cameras, GPS receivers, or Wi-Fi access points to high-gain antennas.
Industrial Control Cabinets: Ideal for compact RF routing within automated machinery and power distribution cabinets where tight bend radii are mandatory.
As a trusted B2B RF coaxial cable manufacturer, Zhenjiang Worldpeak Communication Co., Ltd. offers comprehensive OEM and logistics support to optimize your supply chain:
Compliance & Certifications: The Worldpeak RG58 is fully compliant with CE, RoHS, FCC, and UL94 flammability standards. All manufacturing operates under an ISO9001-certified quality management system.
Custom OEM Assemblies: Worldpeak provides custom jacket branding, colored jackets, and pre-terminated RF jumpers equipped with factory-molded BNC, SMA, TNC, or N-type connectors.
Global Logistics Support: Orders are packed in protective, moisture-barrier spools to preserve shelf-life during long-term warehouse storage. This ensures high-yield performance when deploying the RG58 coaxial cable in large-scale commercial rollouts.
Q: When should I choose the Worldpeak RG58 instead of an RG174 cable?
A: Choose the RG58 coaxial cable when lower signal loss and superior shielding are required. This 50-ohm coaxial cable features 30% lower attenuation than RG174. Select RG174 only when extremely tight physical dimensions override performance needs.
Q: Can this flexible coaxial cable be used outdoors?
A: The standard PVC jacket of the stranded copper RG58 is suitable for indoor and sheltered outdoor runs. For direct burial or intense UV exposure, contact Zhenjiang Worldpeak Communication Co., Ltd. for customized PE or LSZH jacket options.
