Coaxial cable Rangeful TNC male to TNC female RG58/U 50 Ω 0.3 m

Coaxial cable Rangeful TNC male to TNC female RG58/U 50 Ω 0.3 m is a short RF patch lead built on RG58/U 50 Ω coaxial cable with a TNC male connector on one end and a TNC female connector on the other. The 0.3 m length provides a compact connection for radio equipment, antennas, test instruments and other devices that require consistent 50 ohm impedance. The design focuses on straightforward signal transfer and mechanical compatibility with TNC-terminated ports.

Advantages

This coaxial lead offers stable 50 Ω impedance matching to minimize reflections and ensure predictable RF performance across typical VHF/UHF ranges. The TNC male and TNC female connectors provide threaded coupling for secure mechanical connection and improved resistance to vibration compared with push-fit types. The short 0.3 m length reduces signal loss and clutter in dense rack or bench setups while maintaining flexibility for tight routing.

Suitable for

• Connecting radio transceivers to antennas or antenna switches
• Short patch connections between test instruments and RF devices
• Linking TNC-terminated modules in communications equipment
• Bench setups and temporary measurement configurations

Key specifications

• Cable type: RG58/U coaxial
• Characteristic impedance: 50 Ω
• Connector A: TNC male
• Connector B: TNC female
• Length: 0.3 m
• Typical use: RF signal patch lead for VHF/UHF applications

How to use

Identify the TNC male and TNC female ends and align the threaded coupling before engaging. Thread the connectors by hand until snug; avoid over-tightening to prevent damage to connector threads. Route the cable to avoid sharp bends and sustained compression; keep the bend radius larger than the cable diameter to preserve characteristic impedance and minimize insertion loss. For test setups, connect the cable between the instrument output and the device input, verify firm threaded engagement, then power and test the RF path as required.

Usage recommendations

For best results, use this short RG58/U TNC patch lead in indoor, benchtop and rack environments where mechanical stability and short interconnect runs are needed. Avoid outdoor exposure and prolonged mechanical stress; if higher frequency or lower loss is required, consider a cable with lower attenuation or a precision-rated connector assembly.
