Coaxial cable Rangeful RG58-TNCM-SM-2 50 Ω, 2 m, TNC male to SMA male

Coaxial cable Rangeful RG58-TNCM-SM-2 50 Ω, 2 m, TNC male to SMA male is a 2-meter RF interconnect designed for use where a consistent 50 ohm impedance and compact connector interfaces are required. The cable terminates with a TNC male on one end and an SMA male on the other, making it suitable for linking radios, antennas, test instruments and modules that use these common RF connectors. Its construction follows RG58 characteristics to provide predictable attenuation and controlled impedance for signal transmission in laboratory, workshop and field environments.

Advantages

The cable provides reliable 50 Ω impedance matching to reduce signal reflection and preserve RF performance across the link. The TNC and SMA male connectors are widely compatible with corresponding radio, antenna and measurement equipment, enabling straightforward mating without adapters in many setups. At 2 m length the cable offers practical routing flexibility while keeping insertion loss moderate for short- to medium-distance connections.

Suitable for

• Connecting radios and transceivers to external antennas with TNC or SMA interfaces
• Linking signal generators, spectrum analyzers and network analyzers to device under test
• Prototyping and module interconnects in development labs and workshops
• Temporary field connections where a compact, 50 Ω RF link is needed

Key specifications

• Characteristic impedance: 50 Ω
• Cable type: RG58-style coaxial
• Length: 2 m
• Connector A: TNC male
• Connector B: SMA male
• Typical use: RF signal transmission between equipment with TNC/SMA interfaces

How to use

Align the TNC male connector with the TNC female socket and rotate until threaded engagement is secure; avoid over-tightening to prevent connector damage. Insert the SMA male into the SMA female and hand-tighten the coupling nut; use a small torque wrench only if specified by connected equipment to ensure correct mating torque. Route the cable to avoid sharp bends and pinch points, maintaining bend radii consistent with RG58 cable construction to minimize additional loss or mechanical strain.

Usage recommendations

For best RF performance, keep cable runs as short as practical and avoid coiling the cable tightly. Inspect connector interfaces for debris or damage before mating. Where weather exposure or extended outdoor use is expected, consider additional sealing or protective boots on the connector junctions and verify compatibility with the equipment's connector gender and mechanical requirements.
