SR-056-STR is a specialized 0.056" 50-ohm semi-rigid coaxial cable featuring a stranded silver-plated copper-clad steel center conductor that provides exceptional flex fatigue resistance for applications requiring repeated handling, vibration endurance, or frequent reconfiguration. Unlike traditional solid-conductor semi-rigid cables that work-harden and crack after hundreds of bend cycles, the stranded SCCS core maintains electrical integrity through 10,000+ flex cycles while preserving the solid copper outer conductor's benefits of precise impedance control, excellent shielding (>95 dB), and formability for stable RF performance up to 111 GHz. This hybrid construction serves development labs, field service technicians, production test environments, and vibration-prone installations where cable longevity directly reduces maintenance costs and downtime.
Stranded SCCS center conductor - 10,000+ flex cycles vs 500 for solid conductors
0.056" flexible semi-rigid cable- 0.063 minimum bend radius, vibration resistant
50-ohm ±4Ω impedance - VSWR <1.3:1 DC-18 GHz after repeated flexing
Solid copper outer conductor - >95 dB shielding, precise formability maintained
PTFE dielectric - 70% VOP, -55°C to +175°C operation post-flex fatigue
Low Attenuation - 1.17 dB/ft @ 10 GHz, 1.61 dB/ft @ 18 GHz typical
OEM custom lengths - Low MOQ for test lab and field service requirements

RF development laboratories - Test cables for daily handling/reconfiguration cycles
Field service technicians - Portable test equipment surviving repeated setups
Vibration environments - Airborne test gear, vehicle-mounted RF systems
Production test fixtures - Stations requiring frequent cable repositioning
Wireless infrastructure - Temporary test cables during 5G base station deployment
Automotive radar development - Test harnesses with thermal cycling and flexing
Satellite ground testing - Feed cables reconfigured during antenna measurements
Q: Why choose stranded center conductor over solid for test applications?
A: Stranded SCCS resists work-hardening and cracking after repeated flexing. Solid conductors fail after ~500 cycles; SR-056-STR maintains <0.1 dB VSWR shift after 10,000+ cycles at 1.6mm bend radius.
Q: Does stranded construction compromise semi-rigid benefits?
A: No - solid copper outer conductor preserves impedance control, shielding (>95 dB), and formability. Only center conductor is stranded for flex endurance; electrical specs match solid conductor versions.
Q: When to use SR-056-STR vs standard 0.056" semi-rigid coaxial cable?
A: Choose STR for >100 bend cycles, daily handling, vibration, or reconfiguration. Standard solid conductor sufficient for permanent static installations with minimal mechanical stress.
Q: What's the electrical performance trade-off?
A: Negligible - stranded maintains equivalent attenuation (<0.1 dB/ft difference) and power handling to 111 GHz. Primary benefit is mechanical longevity, not electrical superiority.
Q: Can SR-056-STR semi-rigid coaxial cable be factory pre-formed?
A: Yes, identical outer conductor formability to standard semi-rigid cable. Minimum 0.063" bend radius. Factory pre-forming recommended for production.
