Coaxial cable Rangeful TNC male to SMA male RG58/U 50 Ω, 5 m

Rangeful coaxial cable with TNC male to SMA male connectors is a 5 m RG58/U assembly engineered for RF signal transmission where 50 Ω impedance matching is required. The cable combines a TNC male plug at one end and an SMA male plug at the other, mounted on a flexible RG58/U dielectric and shielding structure. It is intended for connecting antennas, radios, test instruments and network devices that use TNC and SMA interfaces. The 5 m length provides reach for indoor routing and installations while keeping insertion loss appropriate for short- to medium-distance RF links.

Advantages

The cable offers reliable 50 Ω characteristic impedance for consistent RF performance and reduced reflection at junctions between SMA and TNC interfaces. Its RG58/U construction provides a balance of flexibility and shielding suitable for indoor installations and bench-top use. Connector-to-connector assembly with standard male TNC and SMA terminations ensures compatibility with a wide range of equipment and makes it straightforward to integrate into existing signal chains.

Suitable for

• Connecting antennas to radios or transceivers with TNC or SMA ports
• Linking test and measurement equipment such as spectrum analyzers and signal generators
• Indoor RF installations and laboratory setups requiring a 5 m interconnect
• Networking equipment and wireless devices that require 50 Ω coaxial cabling

Key specifications

• Cable type: RG58/U coaxial
• Characteristic impedance: 50 Ω
• Connectors: TNC male to SMA male
• Length: 5 meters
• Typical use: indoor and bench-top RF interconnects

How to use

Identify the TNC and SMA ports on the devices to be connected and ensure both connectors match the gender specified (male to female on equipment). Align the TNC male connector with the TNC female receptacle and screw it down until hand-tight; do the same with the SMA male connector, taking care not to overtighten. Route the cable to avoid sharp bends, kinks and proximity to sources of electrical noise. For test measurements, allow for the cable's attenuation when interpreting signal levels.

Usage recommendations

Use the cable indoors or in protected environments; avoid exposure to prolonged moisture, direct sunlight or temperatures outside the intended operating range. Inspect connectors for damage before use and replace the cable if shielding or connectors become degraded. For applications sensitive to loss or VSWR, consider using shorter cable runs or higher-grade low-loss coax if required.
