Material & Craft: 15.88mm solid corrugated copper outer conductor with CCA core
Technical Advantage: 88% velocity & closed-cell foam PE prevents moisture ingress
Performance: High 8kW peak power handling with >90dB RF shielding
The 5/8" corrugated feeder cable manufactured by Zhenjiang Worldpeak Communication Co., Ltd. is a premium 50 ohm transmission line built for low-attenuation signal delivery over medium to long antenna runs. Featuring a 15.88 mm annular corrugated copper outer conductor, a 12.5 mm physical foam PE dielectric, and a 4.0 mm copper-clad aluminum inner conductor, this RF feeder cable provides high power handling, superior structural shielding exceeding 90 dB, and exceptional weather protection. Protected by a 17.3 mm UV-resistant polyethylene jacket, it is engineered for critical telecommunication infrastructure including base stations, broadcast towers, and outdoor wireless systems.
For modern telecommunication networks, preserving signal strength across long vertical transmission lines is essential. The 5/8" corrugated feeder cable engineered by Zhenjiang Worldpeak Communication Co., Ltd. serves as a robust 50 ohm transmission channel designed to bridge base station transceivers with tower-mounted antenna systems.
Unlike conventional braided flexible coax cables, this specialized corrugated copper feeder cable utilizes a solid outer copper wall. The annular corrugation pattern allows the cable to maintain a tight minimum bend radius of 80 mm while retaining structural resistance against crushing, moisture ingress, and environmental stress. Inside, a closed-cell foam polyethylene dielectric delivers an 88% velocity of propagation. This low-density dielectric structure stabilizes the central 4.0 mm copper-clad aluminum conductor, ensuring uniform impedance across wide frequency spectra.
Zhenjiang Worldpeak Communication Co., Ltd. manufactures every meter of this coaxial feeder cable under stringent quality management protocols. The black PE outer jacket protects against UV radiation, thermal expansion, and salt spray exposure, making this base station feeder cable an ideal selection for long-term outdoor infrastructure projects.
Low Signal Attenuation: Solid copper conductor architecture minimizes insertion loss across VHF, UHF, cellular, and microwave bands.
Annular Corrugated Copper Outer Conductor: Provides solid-tube RF shielding (>90 dB) while maintaining controlled flexibility during installation.
High Velocity of Propagation: Advanced 12.5 mm physical foam PE dielectric achieves an 88% velocity factor for rapid, reliable signal transmission.
Weather-Proof Construction: UV-stabilized 17.3 mm black PE jacket resists moisture absorption, ozone degradation, and harsh temperature extremes ranging from -40°C to +85°C.
Lightweight Center Conductor: Uses copper-clad aluminum to optimize high-frequency skin effect conductivity while reducing overall cable weight.
Traditional flexible braided cables contain micro-gaps between woven strands, allowing RF leakage and susceptibility to external electro-magnetic interference (EMI). The 5/8" corrugated feeder cable from Zhenjiang Worldpeak Communication Co., Ltd. employs a continuous solid copper tube. This structural barrier delivers electromagnetic shielding effectiveness exceeding 90 dB, eliminating cross-talk and phase distortion in high-density cell sites.
Water ingress is a primary cause of return loss failure in outdoor RF lines. Zhenjiang Worldpeak Communication Co., Ltd. utilizes closed-cell nitrogen-foamed polyethylene dielectric technology. Because the microscopic gas cells are completely isolated, moisture cannot migrate down the line if the outer jacket is pierced, preserving electrical parameters over long operational lifespans.

While braided options like LMR-400 are easier to bend manually, the 5/8" corrugated feeder cable produced by Zhenjiang Worldpeak Communication Co., Ltd. offers significantly lower attenuation and much higher peak power handling (up to 8.0 kW). LMR-400 exhibits approximately 10.8 dB loss per 100 meters at 900 MHz despite its smaller diameter, whereas this 50 ohm feeder cable delivers superior performance over long vertical runs.
Compared to 1/2" lines, this corrugated copper feeder cable features a larger physical surface area, reducing thermal resistance and signal dissipation. It is the preferred standard when power levels or physical distance demand lower decibel loss per meter.
Cellular Base Station Infrastructure: Serves as the primary main RF feeder cable running from ground-level transceiver shelters to mast-mounted cellular antennas.
VHF/FM Broadcast Systems: Transmits high-power RF signals from radio transmitters to tower antenna arrays without signal degradation.
In-Building Distributed Antenna Systems (DAS): Functions as high-capacity riser trunk cables carrying combined multi-carrier signals across high-rise facilities.
Maritime & Offshore Communications: Resistant to saline air, this base station feeder cable delivers stable communication links on offshore platforms and marine vessels.
Investing in the 5/8" corrugated feeder cable from Zhenjiang Worldpeak Communication Co., Ltd. provides long-term commercial returns by reducing tower maintenance costs and signal degradation outages.
OEM Customization:Zhenjiang Worldpeak Communication Co., Ltd. offers customized jacket printing, color coding, sequential meter marking, and pre-cut lengths.
Factory Cable Assemblies: To lower site labor costs, Zhenjiang Worldpeak Communication Co., Ltd. supplies pre-terminated feeder jumpers fitted with factory-tested 7/16 DIN, 4.3-10, or N-Type connectors.
Export-Grade Packaging: Cables are shipped on reinforced wooden spools designed to protect the copper corrugation during international freight.
Q: Why choose a 5/8" corrugated feeder cable over flexible braided coaxial cables?
A: A 5/8" corrugated feeder cable provides lower attenuation, higher power rating, and solid 90 dB shielding due to its continuous copper outer tube. It is engineered specifically for permanent outdoor towers where braided cables suffer higher signal losses.
Q: What installation precautions should be taken with this corrugated copper feeder cable?
A: Installers must maintain a minimum bend radius of 80 mm and utilize dedicated corrugation stripping tools. Zhenjiang Worldpeak Communication Co., Ltd. recommends using properly rated cable hoisting grips for vertical runs so weight is not supported by the connector interfaces.
Q: Can Zhenjiang Worldpeak Communication Co., Ltd. supply compatible connectors?
A: Yes, Zhenjiang Worldpeak Communication Co., Ltd. provides a complete portfolio of matching 50 ohm RF connectors, including N-Type, 7/16 DIN, and 4.3-10 interfaces tested for low intermodulation (PIM) performance.
