Coaxial Cable No name EK-H155 (YWLXpek 50, conductor 1.17 mm², diameter 3.9 mm)

Coaxial Cable No name EK-H155 (YWLXpek 50) is a compact 50 Ω coaxial cable with a conductor cross-section of 1.17 mm² and an overall diameter of 3.9 mm. It is engineered for RF and signal transmission where low loss and precise impedance matching are required. The cable construction supports consistent characteristic impedance and stable electrical performance in antenna feeds, radio equipment connections, and other installations needing a small-diameter 50 Ω coax.

Advantages

The cable combines a moderate conductor size with a slim outer diameter to offer a balance between flexibility and stable signal transmission. Its 50 Ω impedance is designed to minimise reflections in RF systems. The small diameter makes routing through tight spaces and ducts easier while maintaining reliable electrical characteristics for short- to medium-length runs.

Suitable for

• Antenna feedlines for radio and broadcast equipment
• Connections between transmitters, receivers and RF front-end modules
• Low-loss patching in compact installations and instrument setups
• Temporary and permanent wiring where space is limited

Key specifications

• Characteristic impedance: 50 Ω
• Conductor cross-section: 1.17 mm²
• Overall cable diameter: 3.9 mm
• Cable type: coaxial, single central conductor
• Application: RF and signal transmission, low-loss connections

How to use

Strip the outer jacket, braid and dielectric carefully to expose the centre conductor and the shielding, taking care not to nick the conductor. Terminate with connectors rated for 50 Ω systems and sized to the cable diameter, ensuring a continuous shield-to-connector contact for proper grounding and impedance continuity. Use appropriate crimp or solder methods recommended by the connector manufacturer and verify return loss or VSWR after installation for critical RF paths.

Usage recommendations

For best performance, avoid tight bending radii and repeated flexing near connectors; follow recommended minimum bend radius guidelines for the cable diameter. Keep cable runs as short as practical for reduced insertion loss, and use quality 50 Ω connectors and tools to maintain low reflections and reliable signal transfer.
