Coaxial Cable Rangeful RG58/U 50 Ohm 12 m — TNC Male to SMA Male

Rangeful RG58/U 50 Ohm coaxial cable, 12 m in length, fitted with a TNC male connector on one end and an SMA male connector on the other. This cable is designed for 50 Ω RF and antenna connections and uses the common RG58/U construction to provide flexible routing and consistent signal transmission between equipment with TNC and SMA interfaces.

Advantages

The cable combines standard RG58/U flexible dielectric and braid shielding to maintain impedance uniformity and reduce signal loss over the 12 m run. TNC male and SMA male connectors offer secure threaded connections that resist vibration and provide reliable mechanical and electrical contact. The 50 Ω characteristic impedance makes the cable compatible with a wide range of RF devices, test instruments and antenna systems requiring controlled impedance.

Suitable for

• Connecting radio transceivers to external antennas with TNC and SMA ports
• Linking test equipment and measurement instruments in RF laboratory setups
• Extending or adapting cables between devices with TNC and SMA connectors
• Networking and telemetry installations that require 50 Ω coaxial connections

Key specifications

• Cable type: RG58/U coaxial
• Impedance: 50 Ω
• Length: 12 m
• Connector A: TNC male (threaded)
• Connector B: SMA male (threaded)
• Construction: flexible dielectric with braided shielding for RF use

How to use

Ensure both connected devices are powered off before attaching the cable. Align the TNC male connector with the TNC female port and thread until hand-tight to secure the connection; do the same for the SMA male connector into the SMA female port. Avoid over-tightening with tools—hand-tight plus a small quarter-turn with a torque wrench (if available) is sufficient. Route the cable to minimize tight bends and avoid sharp kinks; maintain gentle curves to preserve cable impedance and reduce return loss. After installation, power devices and verify signal integrity and expected RF performance.

Usage recommendations

For stable RF performance, avoid routing the cable near high-power AC lines or large metallic objects that can cause interference. Periodically inspect connectors for corrosion or mechanical wear and replace the cable if shielding or connectors are damaged. Use appropriate adapters only when necessary and ensure adapter impedance matches 50 Ω to prevent signal reflections.
