Coaxial cable Rangeful TNC male to SMA male RG58/U 50 Ω 0.5 m

Rangeful TNC male to SMA male coaxial cable, 0.5 m, is a flexible RF interconnect built on RG58/U coax with 50 Ω impedance. The cable provides a compact, short-link connection between devices that use TNC and SMA male ports. Its construction targets low-loss signal transfer for test setups, antennas, radio equipment and laboratory instrumentation where a short, reliable RF connection is required.

Advantages

The cable combines a TNC male connector on one end and an SMA male connector on the other to allow direct mating between differing connector types without adapters. Built on standard RG58/U coaxial dielectric and shielding, it maintains 50 Ω characteristic impedance for minimal reflection and controlled insertion loss across typical VHF/UHF frequencies. Its 0.5 m length offers a tidy routing option for bench and rack environments while preserving mechanical flexibility for easy handling and connector mating.

Suitable for

• Connecting test equipment and measurement instruments with TNC and SMA ports
• Short antenna feed lines for radio transceivers and receivers
• Lab setups and prototyping where compact RF jumpers are needed
• RF modules and evaluation boards requiring a 50 Ω interconnect

Key specifications

• Cable type: RG58/U coaxial
• Characteristic impedance: 50 Ω
• Connector A: TNC male
• Connector B: SMA male
• Length: 0.5 m
• Typical use: short RF interconnects (low-loss jumper)
• Construction: flexible dielectric with braided shielding

How to use

Ensure both connected devices are powered off or in a safe state for handling RF connectors. Align the TNC male and SMA male connectors to their corresponding female ports and hand-tighten until secure; do not overtighten to avoid damaging threads. Route the 0.5 m cable to avoid sharp bends or kinks and keep it clear of high-voltage or noisy power lines to reduce interference. After connection, power up equipment and verify signal integrity or continuity as required by the specific test or installation.

Usage recommendations

For best RF performance, use this 50 Ω jumper for short distances and avoid running it alongside high-current cables. Periodically inspect connector interfaces for contamination or wear, and replace the cable if you observe degraded signal levels or physical damage. If measurements require calibrated loss data, include the cable’s insertion loss in the measurement chain or use a known-calibration standard.
