Description
Product Description

True Flex 316 spiral strip coax is a high-performance 50 ohm flexible coaxial cable engineered for applications requiring reliable signal transmission up to 18 GHz. Combining a stranded silver‑plated copper conductor, dual-layer spiral + braid shielding, and a rugged FEP jacket, this cable delivers exceptional flexibility, durability, and electrical stability.Designed as a direct form and function‑equivalent to the industry‑standard Harbour SFL405‑105FLEX, True Flex 316 offers identical electrical parameters while featuring a chemical‑resistant FEP jacket for enhanced performance in harsh environments.

Core Advantages

  • Stranded Silver‑Plated Copper Center Conductor – Provides excellent flexibility and conductivity, ideal for repeated flexing and tight installations.

  • Dual‑Layer Shielding – Spiral silver‑plated copper strip plus round silver‑plated copper braid ensures > –110 dB shielding effectiveness (typical).

  • FEP Jacket – Chemically inert, low‑friction, and rated for continuous operation from –55°C to +105°C; resists solvents, oils, and abrasion.

  • Precision 50Ω Impedance – Maintains low VSWR across the entire DC‑18 GHz frequency range.

  • Excellent Phase Stability – Reliable performance under flexure, suitable for test and measurement applications.

  • Drop‑in Replacement for SFL405 – Identical mechanical dimensions, electrical specs, and attenuation profile as Harbour SFL405‑105FLEX.

Application Scenarios

  • Defense Electronics: Phase stability, high reliability, wide temperature range

  • Test and Measurement: Low VSWR, repeatable performance after flexing, connector compatibility

  • Wireless Communications: Low loss, high frequency support (5G/mmWave ready)

  • Medical Electronics: FEP jacket options, flexibility, small bend radius,flexible, low loss,

  • PIM Test Cables: Low passive intermodulation, high shielding effectiveness

Why to Choose Our Spiral Strip Coax?

Engineers and system designers choose True Flex 316 when they need a flexible microwave cable that delivers the electrical performance of semi-rigid construction—featuring low loss, low VSWR, and > –110 dB shielding effectiveness—combined with the mechanical flexibility required for tight bends and repeated flexing. Built with a stranded silver-plated copper conductor and dual-layer spiral + braid shielding, it ensures reliable signal integrity up to 18 GHz while the chemical-resistant FEP jacket withstands harsh environments from –55°C to +105°C. With industry-standard 2.92 mm dimensions, it serves as a direct drop-in replacement for Harbour SFL405-105FLEX, offering wide compatibility with off-the-shelf connectors such as SMA and 2.92mm. Proven reliability in defense, aerospace, and test & measurement applications makes True Flex 316 the trusted choice for mission-critical RF systems.
