Coaxial cable Rangeful TNC male to TNC female RG58 50 Ω, 2 m

Rangeful TNC male to TNC female coaxial cable, 2 m, built on RG58 with 50 Ω impedance provides a flexible RF link for antennas, radio equipment and test setups. The cable assembly maintains impedance continuity for reliable signal transfer over a short extension or connection between devices with TNC terminations. Its 2-m length offers moderate reach while keeping signal loss and handling simple in bench or field installations.

Advantages

This RG58 coaxial lead combines a TNC male connector on one end and a TNC female connector on the other to allow direct mating without adapters. The 50 ohm characteristic impedance matches standard RF systems to minimise reflections and preserve signal integrity. The 2 m length balances convenience and low insertion loss, while the flexible jacket and standard RG58 construction make routing and handling straightforward in tight spaces.

Suitable for

• Connecting antennas to radio transceivers with TNC interfaces
• Extending RF test equipment leads in laboratories and workshops
• Linking network or telemetry modules in measurement setups
• Temporary or permanent connections in field radio and wireless installations

Key specifications

• Cable type: RG58 coaxial
• Characteristic impedance: 50 Ω
• Length: 2 m
• Connector configuration: TNC male → TNC female
• Typical use: RF signal transmission, antenna feeds, test leads
• Construction: flexible jacket suited for indoor and light field use

How to use

Align the TNC male connector with the TNC female thread and rotate the coupling nut until it is hand-tight; avoid over-tightening to protect connector threads and centre contacts. Route the cable to avoid sharp bends and excessive tension — maintain a bend radius consistent with RG58 flexibility to prevent deformation or increased loss. For test setups, connect the cable between the instrument and device with matching 50 Ω terminations to ensure correct measurement conditions.

Usage recommendations

Inspect connectors for dirt or damage before use and clean contacts with appropriate, non-abrasive methods if necessary. Use the 2 m length for short to moderate runs; for longer distances consider lower-loss cable types or active amplification, and always match 50 Ω systems end-to-end to prevent impedance mismatch and signal reflections.
