Coaxial cable Rangeful TNC male to SMA male RG58/U 50 Ω, 7 m

Rangeful TNC male to SMA male coaxial cable, built on RG58/U with 50 Ω impedance and 7 m length, provides a straightforward RF connection between equipment fitted with TNC and SMA ports. The cable is intended for short runs and indoor installations where a flexible, standard-impedance link is required. It supports typical RF tasks such as connecting antennas, routers, test instruments and amateur radio gear while maintaining characteristic 50-ohm matching.

Advantages

The cable combines an industry-standard RG58/U core with TNC male and SMA male connectors to ensure reliable mechanical coupling and consistent electrical performance at RF frequencies. Its 7 m length offers extended reach without the stiffness of larger-diameter coax. The 50 Ω characteristic impedance reduces reflections in matched systems. Flexible construction eases routing in confined indoor spaces and simple hand-installation.

Suitable for

• Connecting antennas to routers or modems with mismatched port types (TNC ↔ SMA)
• Linking RF test equipment and measurement instruments
• Short-run connections in amateur radio setups and ham rigs
• Indoor installations where flexibility and moderate length are required

Key specifications

• Cable type: RG58/U coaxial
• Impedance: 50 Ω characteristic
• Connectors: TNC male to SMA male
• Length: 7 meters
• Use environment: indoor, short cable runs

How to use

Connect the TNC male end to the device with a TNC female port and the SMA male end to the device or antenna with an SMA female port. Ensure connectors are aligned and screw them gently until hand-tight; avoid over-torquing which can damage connector threads or impair the RF joint. Route the cable to minimize sharp bends and avoid kinks; maintain bend radii appropriate to flexible RG58-type cable. When used with sensitive measurement equipment, verify continuity and SWR where applicable to ensure acceptable signal transfer.

Usage recommendations

For best results, use the cable within its intended indoor environment, avoid prolonged exposure to moisture or direct outdoor elements, and inspect connectors for dirt or corrosion before mating. When higher frequency performance or lower loss is required, consider a low-loss or larger-diameter coax alternative.
