Engineered for durability: inside our armored RF cables
The attenuation and signal integrity of the ARX Series armored coaxial cable are strictly determined by its physical structure and material composition. The transmission core consists of a silver-plated copper center conductor insulated by a microporous PTFE dielectric. This dielectric layer dictates the cable's electrical parameters, limiting capacitance to 86.8 pF/m and ensuring a velocity of propagation of 77%.
To withstand harsh environmental factors while maintaining a shielding effectiveness greater than 90 dB, the cable architecture includes dual-layer shielding. A helical silver-plated copper tape serves as the inner shield, overlaid with a silver-plated copper outer braid. Encased in an FEP jacket, the ARX Series armored flexible cable maintains consistent amplitude and mechanical phase stability during repeated bending operations.
