Semi-Flexible Coax Cable

Semi-Flexible cable,also known as hand- formable cable,combined with semi-rigid and flexible coaxial cable, it is the same size as standard semi-rigid cable thus enabling use of all of the same connectors and tooling,but offers an even more flexible alternative.
Application: Semi Flexible Coaxial Cable is used for internal connection in black box, base station of mobile, delay line, microwave, radio-frequency equipment and all other electronic equipment.

Semi-Flexible vs Semi-Rigid vs Flexible Cable

Feature	Flexible Cable	Semi-Flexible Cable	Semi-Rigid Cable
Outer Conductor	Braided copper	Tin-dipped braided copper	Seamless solid metal tube
Flexibility	Highly flexible, can be bent repeatedly	Hand-formable, holds shape after bending	Rigid, requires tools to form
Shielding	Good (85-95%)	Excellent (>90%)	Best (100% RF shielding)
Phase Stability	Moderate	High	Highest
Ease of Installation	Easiest	Easy, holds shape	Requires precision tooling
Cost	Lowest	Moderate	Highest
Typical Applications	General RF, consumer electronics	5G base stations, aerospace RF modules	Microwave systems, defense, test equipment

Summary:

• Choose flexible cable for cost-sensitive, general-purpose RF connections.
• Choose semi-flexible cable when you need better shielding and phase stability than flexible cable, but easier installation than semi-rigid.
• Choose semi-rigid cable for mission-critical microwave applications requiring maximum performance.

Advantages Over Flexible Cable

Semi-flexible coax cable offers several key advantages compared to standard flexible coax:

• Better Shielding: The tin-dipped braided outer conductor provides superior EMI/RFI isolation (>90 dB), reducing signal interference in sensitive RF systems.
• Shape Retention: Unlike flexible cable, semi-flexible cable holds its shape after bending, simplifying cable routing and reducing the need for cable ties or clamps.
• Higher Phase Stability: More stable electrical performance under vibration and temperature changes, critical for aerospace and defense applications.
• Lower Loss: Improved impedance control and reduced signal attenuation compared to flexible braided cables.
• Durability: More resistant to wear, shock and vibration, extending service life in harsh environments.
