Coaxial cable Rangeful TNC Male–TNC Male RG58 50 Ω, 20 m

Rangeful coaxial cable with TNC male connectors at both ends is a 20-meter RG58 cable designed for 50 Ω RF signal transmission. The cable provides a flexible, shielded connection suitable for antenna leads, test instruments and network equipment that use TNC interfaces. Constructed to maintain signal integrity over its length, this cable is intended for installations and field use where a reliable coaxial link is required.

Advantages

This RG58 50 Ω coaxial assembly combines a standardized impedance with TNC male terminations to minimize reflections and preserve RF performance. The 20 m length offers extended reach without intermediate adapters, while the flexible jacket and shielding reduce microphonic effects and external interference. TNC male connectors provide secure threaded coupling for vibration-resistant connections in both fixed installations and mobile environments.

Suitable for

• Antenna connections for wireless equipment and routers with TNC interfaces
• Laboratory and field testing with RF test instruments
• Point-to-point RF links and monitoring systems
• Network devices and modems requiring 50 Ω coaxial cabling

Key specifications

• Cable type: RG58
• Impedance: 50 Ω
• Connector type: TNC male — TNC male
• Length: 20 m
• Shielding: braided shield with foil (typical for RG58 assemblies)
• Center conductor: stranded copper (typical for flexible RG58)
• Outer jacket: flexible PVC (suitable for indoor and light field use)

How to use

Connect each TNC male connector to the corresponding TNC female port, ensuring the threaded coupling is hand-tightened until secure. Route the cable to avoid sharp bends and prolonged compression; maintain bend radii consistent with flexible RG58 practice to prevent performance degradation. For test setups, connect the cable between the signal source and measurement device, verifying 50 Ω termination and that connectors are clean and undamaged before use.

Usage recommendations

For best RF performance, avoid kinking the cable and minimize exposure to moisture. When used outdoors or in harsh environments, consider additional protective sleeving or weatherproofing at connector interfaces. Periodically inspect connectors for corrosion or wear and replace the assembly if shielding or conductor integrity is compromised.
