Coaxial cable Rangeful RG58 TNC male to TNC female, 50 Ω, 7 m

Rangeful RG58 TNC male to TNC female coaxial cable, 50 Ω, 7 m, is a medium-length RF connection cable designed for general-purpose radio frequency signal transmission. The cable uses RG58 construction with braided shielding and a dielectric core to maintain characteristic impedance and reduce signal loss across a 7-meter run. TNC male and TNC female connectors provide threaded coupling for secure connections in antenna systems, test equipment setups and other RF applications requiring reliable 50-ohm performance.

Advantages

The cable provides a consistent 50 Ω impedance along its length, minimizing reflections and preserving signal integrity for analog and digital RF signals. Its RG58 flexible design allows easier routing in crowded installations while braided shielding reduces electromagnetic interference. Threaded TNC connectors ensure a stable mechanical and electrical connection, suitable for moderate-vibration environments and repeated mating cycles.

Suitable for

• Connecting antennas to radio transceivers and receivers
• Linking test and measurement equipment in RF labs
• Short- to medium-distance connections in wireless communication setups
• Prototyping and bench work where a flexible 7 m cable is required

Key specifications

• Impedance: 50 Ω
• Cable type: RG58 coaxial
• Connectors: TNC male to TNC female, threaded coupling
• Length: 7 m
• Shielding: braided shield (single or double braid typical for RG58 construction)
• Typical use: RF signal transmission for radio, antenna and test equipment

How to use

Inspect connectors and cable for visible damage before installation. Align the TNC male and TNC female connectors, engage the threaded coupling and tighten by hand until secure; avoid over-tightening with tools to prevent connector damage. Route the cable to minimize sharp bends and avoid kinks; maintain bend radius appropriate for RG58 to prevent impedance changes. For test setups, connect the cable between instrument ports and verify signal continuity and return loss with appropriate equipment.

Usage recommendations

For best performance, keep the cable run as short as practical and avoid running alongside power lines or noisy digital cables. Periodically inspect the threaded TNC connections for corrosion or wear and replace the cable if shielding integrity is compromised. Use strain relief at connection points to extend service life in installations with movement or vibration.
