Our True‑Flex 141 spiral strip coax stands out as a top‑tier flexible microwave cable because it uniquely combines the high electrical performance of MIL‑DTL‑17 semi‑rigid cables with the true flexibility and ease of use of standard flexible RF cables. It delivers extremely low leakage, low VSWR, and stable high‑frequency performance up to 26.5 GHz, supported by a dual silver‑plated copper shielding structure that provides more than 90 dB shielding effectiveness for superior signal integrity. The solid PTFE dielectric and tight impedance control ensure consistent, low‑loss transmission across the full operating band. With a wide temperature range from –65 °C to +200 °C, excellent durability, and optimized static and dynamic bending radii, this cable performs reliably under harsh conditions, repeated bending, and mechanical stress. At just 49 g/m, its lightweight design simplifies installation and reduces system weight, while full compatibility with standard 141 semi‑rigid connectors eliminates extra tooling costs and shortens assembly time. Fully manufactured to industrial‑grade quality standards, True‑Flex 141 offers outstanding reliability, cost‑efficiency, and versatility, making it the ideal choice for high‑frequency applications that demand both top‑level electrical performance and practical flexibility.
