Optimized Structure for Consistent Electrical Performance

The CFA370 cable incorporates a silver-plated copper inner conductor (0.91 mm) and a low-density PTFE dielectric to minimize attenuation and maintain phase integrity across bending cycles. Its dual silver-plated copper shielding and FEP jacket offer > 90 dB shielding effectiveness and outstanding thermal resilience from –55 °C to +165 °C, supporting stable performance over time.

Flexible and Durable Design for Dynamic RF Use

With a 3.75 mm outer diameter and a minimum bend radius of 19 mm, the CFA370 phase-stable cable provides a balanced combination of mechanical flexibility and electrical stability. Its lightweight 36 g/m construction and FEP sheath ensure ease of installation and reliable signal transmission even under continuous motion.
