RFS CellFlex Hard Line Assemblies – Low Loss 50 Ohm Pre-Terminated Coax Cables

Our RFS CellFlex Hard Line Assemblies are pre-terminated low loss 50 Ohm coaxial cables built with genuine RFS CellFlex copper corrugated hard line coax. These assemblies provide very low attenuation and high shielding, making them ideal for long feedlines in high-performance RF systems.

RFS CellFlex cable is designed as a direct alternative to Andrew Heliax hard line coax. Both cable types use a corrugated copper outer conductor and a low-loss foam dielectric, providing very similar electrical performance and attenuation values. CellFlex meets or exceeds Heliax specifications for shielding effectiveness, low attenuation, and flexibility for installation.

Key Features:

• ✅ Genuine RFS CellFlex copper corrugated hard line coaxial cable
• ✅ Very low loss 50 Ohm performance for HF, VHF, UHF, microwave frequencies
• ✅ High shielding effectiveness (≥120 dB typical)
• ✅ Corrugated copper outer conductor for flexibility and crush resistance
• ✅ Low-loss foam dielectric
• ✅ Factory pre-terminated and tested with precision RF connectors

Specifications:

• ✅ Cable Type: RFS CellFlex Hard Line
• ✅ Impedance: 50 Ohms
• ✅ Outer Conductor: Corrugated copper tube
• ✅ Inner Conductor: Copper tube or solid copper wire (varies by model)
• ✅ Dielectric: Low-loss foam PE
• ✅ Shielding Effectiveness: ≥120 dB typical
• ✅ Attenuation (typical 1/2" size):
