Material & Craft: 13.8mm annular corrugated copper outer conductor with CCA core
Technical Advantage: 86% velocity & closed-cell foam PE prevents moisture ingress
Performance: 12kW peak power capacity with >90dB RF shielding
Zhenjiang Worldpeak Communication Co., Ltd. presents the premium 1/2in corrugated feeder cable, an engineered 50 ohm RF feeder cable designed for demanding wireless infrastructure. Featuring a solid annular corrugated copper feeder cable outer conductor and closed-cell foam polyethylene dielectric, this cable delivers exceptional shielding efficiency exceeding 90 dB alongside ultra-low signal attenuation. Built with a durable 15.7 mm black polyethylene jacket and a copper-clad aluminum inner conductor, this 50 ohm feeder cable offers superior power handling and long-term mechanical reliability. It provides the optimal high-performance transmission line for cellular base stations, broadcast towers, and in-building antenna systems.
The 1/2in corrugated feeder cable manufactured by Zhenjiang Worldpeak Communication Co., Ltd. serves as a critical transmission bridge between radio transceivers and high-gain tower-mounted antennas. Designed specifically for outdoor telecom infrastructure, this flexible yet ultra-durable RF feeder cable balances mechanical flexibility with optimal signal integrity.
Unlike traditional braided coaxial cables, a solid annular corrugated copper feeder cable utilizes a continuous copper tube shield. This construction eliminates high-frequency RF leakage, reduces signal distortion, and maintains stable impedance across wide operating temperature bands ranging from -40°C to +85°C. Combined with a precision-extruded closed-cell foam dielectric, the cable yields an impressive 86% velocity of propagation.
Solid Annular Shielding: The 13.8 mm outer conductor uses annular corrugated copper to provide solid-tube electromagnetic shielding exceeding 90 dB while allowing a controlled 125 mm bend radius.
Low-Loss Dielectric Core: High-expansion 12.3 mm foam polyethylene dielectric minimizes capacitive losses (77.0 pF/m) and blocks internal moisture migration.
Optimized Center Conductor: A 4.8 mm copper-clad aluminum center conductor balances low DC loop resistance (1.8 ohm/km) with reduced overall weight for easier tower rigging.
All-Weather UV Jacket: Encased in a 15.7 mm heavy-duty black polyethylene outer sheath, this low loss feeder cable withstands extreme UV radiation, ozone exposure, and harsh environmental weathering.
High Power Capability: Designed to handle peak power ratings up to 12 kW with a DC withstand voltage rating of 4000V.
In high-frequency wireless networks, attenuation directly impacts coverage radius and power consumption. The continuous copper tube in this 1/2in corrugated feeder cable eliminates the microscopic gaps inherent in braided shields (such as LMR-series or RG-series cables). This results in significantly lower attenuation, yielding approximately 8.5 dB/100m at 900 MHz and 14.5 dB/100m at 2.4 GHz.
Moisture ingress is the primary cause of signal degradation in outdoor transmission systems. Zhenjiang Worldpeak Communication Co., Ltd. integrates closed-cell foam technology into the dielectric layer. Even if the outer jacket experiences damage, the closed-cell matrix prevents moisture from migrating longitudinally through the RF feeder cable, preserving system performance over decades.

Used extensively as main vertical feeders connecting ground shelter transceivers to top-of-tower antennas in macrocell cellular sites.
Serves as high-capacity backbone riser cables in Distributed Antenna Systems (DAS) across commercial facilities, airports, and sports venues.
Acts as a low-loss 50 ohm feeder cable for FM radio, VHF broadcast, and private trunked radio systems demanding uncompromised signal fidelity.
The solid copper shield and heavy PE jacket make this corrugated copper feeder cable highly resistant to salt-spray corrosion in offshore oil platforms and maritime vessels.
When sourcing from Zhenjiang Worldpeak Communication Co., Ltd., global distributors, telecommunication operators, and system integrators gain distinct commercial advantages:
Custom Cable Assemblies: Factory-terminated jumper assemblies utilizing 4.3-10, N-Type, or 7/16 DIN connectors, thoroughly pre-tested for low PIM and VSWR before shipment.
OEM Customization: Private-label jacket printing, customized length marking, and project-specific packaging options.
Supply Chain Efficiency: Heavy-duty wooden reel packaging engineered for safe international maritime freight and rapid site deployment.
Lower Total Cost of Ownership: Reduced signal loss lowers base station power demands, while robust construction minimizes maintenance calls over a 20+ year service life.
A 1/2in corrugated feeder cable utilizes a solid corrugated copper outer shield, whereas LMR400 uses a foil-and-braid shield. The solid copper tube provides superior shielding effectiveness (>90 dB vs. ~90 dB braided), lower signal attenuation, and superior long-term stability in extreme weather conditions.
Because a corrugated copper feeder cable utilizes a solid copper shell, installation requires specialized stripping and flaring tools to prepare the cable profile correctly before connector attachment. Zhenjiang Worldpeak Communication Co., Ltd. offers both preparation tools and pre-terminated factory jumper assemblies.
Industry-standard 1/2-inch feeder connectors are fully compatible, including 4.3-10, N-Type, and 7/16 DIN connector interfaces.
