Coaxial cable Rangeful TNC male–TNC male RG58/U 50 Ω, 0.3 m

Rangeful TNC male–TNC male RG58/U 50 Ω coaxial cable, 0.3 m is a short RF patch lead built on standard RG58/U coaxial construction. The cable provides a compact 50 ohm connection with TNC male connectors on both ends, intended for reliable transmission of radio frequency signals in applications that require minimal signal reflection and consistent impedance. With its 0.3 m length it is suitable where a short, low‑loss jumper is needed between equipment, antennas or test instruments.

Advantages

This Rangeful coaxial lead offers consistent 50 Ω impedance for RF signal integrity and compatibility with devices designed to use RG58 type cable. TNC male connectors provide a secure threaded coupling for vibration resistance and improved mechanical stability compared with push‑fit connectors. The short 0.3 m length reduces insertion loss and limits signal degradation over the connection, making it useful in confined arrangements and bench setups.

Suitable for

• Connecting RF equipment and test instruments in a lab or workshop
• Linking antennas to transceivers or extension adapters
• Telecommunication systems and signal distribution where 50 Ω matching is required
• Amateur radio stations and short patch connections
• Temporary measurement and calibration setups

Key specifications

• Impedance: 50 Ω
• Cable type: RG58/U coaxial
• Connector A: TNC male (threaded)
• Connector B: TNC male (threaded)
• Length: 0.3 m
• Typical use: RF signal transmission, patch lead

How to use

Align the TNC male connectors with the threaded TNC female sockets on your devices and rotate the coupling nut until hand‑tight; avoid excessive force to prevent damage to the connector. Use the 0.3 m lead to bridge short distances between antennas, transceivers, spectrum analyzers, network analyzers or other 50 Ω ports. When installing in test setups, ensure connectors are clean and free from debris to maintain good electrical contact and low insertion loss.

Usage recommendations

For optimal performance, keep the cable run as short and straight as practical and avoid sharp bends or kinks. Store the cable coiled loosely and protect connectors with caps when not in use. Verify compatibility of device ports with TNC male connectors and 50 Ω systems before connecting.
