The ETL-COX-1/2SF Super Flexible Feeder Cable is engineered for high-performance telecommunication systems where space is limited and tight bends are required. With a 50 Ohm impedance and a specialized Foam PE insulation, this cable ensures minimal signal attenuation and maximum shielding efficiency for RF applications.
Key Features
-
Super Flexible Design: Smaller bending radius compared to standard 1/2″ cables, making it much easier to install in compact cabinets and curved cable trays.
-
High-Efficiency Transmission: Features a 3.60mm Copper-Clad Aluminum (CCA) inner conductor for excellent conductivity and reduced weight.
-
Superior Insulation: High-expansion Foam Polyethylene (PE) ensures stable dielectric properties and low loss.
-
Industrial Grade: Built for telecommunication infrastructure, wireless base stations, and antenna systems.
