RFS 1/2" CellFlex Hard Line Assemblies – Low Loss 50 Ohm Pre-Terminated Coax Cables
Our RFS 1/2" CellFlex Hard Line Assemblies are pre-terminated low loss 50 Ohm coaxial cables built with genuine RFS 1/2 inch CellFlex copper corrugated hard line coax. These assemblies provide excellent low attenuation and high shielding, making them ideal for long RF feedlines.
RFS CellFlex 1/2 inch hard line is a direct alternative to Andrew Heliax LDF4-50A series, providing comparable attenuation, shielding, and mechanical flexibility. The 1/2 inch size is commonly used for high power and low loss applications where superior performance is required.
Key Features:
- ✅ Genuine RFS 1/2" 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 1/2"
- ✅ Impedance: 50 Ohms
- ✅ Outer Conductor: Corrugated copper tube
- ✅ Inner Conductor: Copper tube
