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.
