Material & Craft: 12.1mm spiral corrugated copper outer conductor with CCA core
Technical Advantage: 50mm superflex bend radius & 86% velocity with foam PE
Performance: 10kW peak power capacity with >90dB RF shielding
Zhenjiang Worldpeak Communication Co., Ltd. supplies the high-performance 1/2" Superflex feeder cable, a specialized 50 ohm RF feeder cable engineered for complex routing environments. Built with a 12.1 mm spiral corrugated copper feeder outer conductor and an 8.8 mm closed-cell foam polyethylene dielectric, this cable provides exceptional flexibility with a tight 50 mm minimum bend radius. Featuring a 3.6 mm copper-clad aluminum inner conductor and a 13.4 mm black UV-resistant polyethylene jacket, this flexible 1/2 coaxial cable offers low signal attenuation, 90 dB shielding efficiency, and 10 kW peak power capability. It serves as the ideal high-frequency low loss feeder cable for cabinet interconnects, in-building DAS risers, and rooftop antenna jumpers.
The 1/2" Superflex feeder cable engineered by Zhenjiang Worldpeak Communication Co., Ltd. bridges the gap between rigid high-power trunk cables and highly flexible jumper lines. Standard annular feeder cables excel at long vertical runs on telecom towers, but their rigid structure makes routing through narrow equipment enclosures or tight cabinet exits difficult.
To solve this challenge, Zhenjiang Worldpeak Communication Co., Ltd. incorporates continuous spiral corrugation in the outer solid copper tube shield. This construction allows the 1/2" Superflex feeder cable to achieve a tight 50 mm installation bend radius without risking outer conductor kinking, internal mechanical stress, or impedance discontinuities.
Supported by an 8.8 mm high-expansion closed-cell foam polyethylene dielectric, this RF feeder cable achieves an 86% velocity of propagation. The 3.6 mm copper-clad aluminum inner conductor optimizes skin effect conductivity at radio frequencies while reducing the net cable weight to just 0.21 kg/m. Wrapped in a durable 13.4 mm weather-resistant polyethylene jacket, this 50 ohm feeder cable withstands extreme outdoor thermal cycling from -40°C to +85°C.
Ultra-Flexible Spiral Shielding: The 12.1 mm spiral corrugated copper feeder tube allows a 50 mm bend radius, enabling easy installation in confined equipment spaces.
Solid Copper Shielding: Delivers shielding effectiveness greater than 90 dB, eliminating high-frequency RF leakage and preventing external signal interference.
Closed-Cell Foam Core: The 8.8 mm foam PE dielectric limits moisture ingress along the flexible 1/2 coaxial cable, preserving signal integrity over long operational cycles.
Optimized Center Conductor: A 3.6 mm copper-clad aluminum inner conductor balances conductivity and light weight, featuring a low DC loop resistance of 3.1 ohm/km.
Rugged Weatherproof Sheath: The 13.4 mm black polyethylene outer jacket resists severe ultraviolet radiation, chemical exposure, and mechanical abrasion.
Standard 1/2-inch annular feeder cables typically require a minimum bend radius of approximately 125 mm. Bending an annular cable beyond its limit causes irreversible outer tube buckling. By utilizing a spiral geometry, Zhenjiang Worldpeak Communication Co., Ltd. enables engineers to route the 1/2" Superflex feeder cable through tight 50 mm bends. While spiral corrugation exhibits slightly higher attenuation (13.0 dB/100m at 900 MHz) compared to rigid trunk cables, it provides the flexibility needed for short-run interconnects where installation space is severely limited.
Compared to braided coaxial lines like LMR400 or RG214, this low loss feeder cable employs a seamless, solid copper tube conductor. Braided cables often suffer from braid degradation, moisture penetration, and passive intermodulation distortion over time. The solid outer sheath of this spiral corrugated copper feeder guarantees permanent 90 dB shielding efficiency, higher power handling (10 kW peak power), and extended operational stability in severe outdoor climates.

Ideal for connecting outdoor radio units and transceiver cabinets to antenna ports where the tight 50 mm bend radius facilitates clean routing inside narrow cable trays.
Serves as flexible distribution cables within Distributed Antenna Systems (DAS), simplifying routing through wall penetrations, ceiling spaces, and service riser closets.
Used for short jumper connections on crowded urban rooftops, allowing installers to navigate tight corners around mounting frames and structural barriers.
Provides durable, vibration-resistant RF links for shipboard radar, offshore platform rigs, and mobile broadcast units requiring flexible 50 ohm feeder cable assemblies.
Partnering with Zhenjiang Worldpeak Communication Co., Ltd. delivers direct strategic advantages to global network operators, OEM integrators, and distributors:
Factory-Terminated Assemblies: Zhenjiang Worldpeak Communication Co., Ltd. supplies pre-cut, factory-assembled jumper lines terminated with 4.3-10, N-Type, or 7/16 DIN connectors, tested for low insertion loss and VSWR performance.
Custom OEM Branding: Custom jacket legend printing, sequential meter markings, and private-label packaging are available for bulk commercial orders.
Optimized Logistics: Delivered on sturdy, export-ready wooden spools designed to protect cable geometry during international ocean and air transport.
Reduced Labor Costs: The flexible spiral design allows rapid field installation without needing complex bending tools, lowering labor time and overall installation costs.
The primary difference lies in the corrugation design. Standard 1/2" feeders use annular corrugation with a 125 mm bend radius for main vertical runs. This 1/2" Superflex feeder cable utilizes spiral corrugation, reducing the minimum bend radius to 50 mm for tight routing in jumper and cabinet applications.
While this low loss feeder cable can be used over longer runs, spiral corrugation has slightly higher attenuation per meter than standard annular feeders. It is best utilized for short jumpers, cabinet interconnects, and DAS risers where flexibility is critical.
Zhenjiang Worldpeak Communication Co., Ltd. provides dedicated 1/2" Superflex connectors, including 4.3-10, N-Type, and 7/16 DIN interfaces engineered specifically for spiral outer conductor profiles.
