Coaxial cable Rangeful Mini UHF male to SO239 UHF RG58 50Ω, 3 m

Rangeful Mini UHF male to SO239 UHF RG58 50Ω, 3 m is a 3‑metre RF patch lead designed for connecting transceivers, antenna systems and RF equipment where compact UHF connectors are required. Built with RG58 coaxial construction and a nominal 50 ohm impedance, the cable provides a consistent transmission path for VHF/UHF and CB frequencies. The lead pairs a Mini UHF male plug with a SO239 UHF socket, enabling straightforward mating with devices and antenna mounts that accept UHF sockets.

Advantages

The cable combines flexible RG58 dielectric and braided shield construction to deliver reliable RF continuity and manageable routing in tight installations. The Mini UHF male and SO239 UHF socket interface are common in amateur radio and CB equipment, offering secure mechanical connection and good electrical contact for typical mobile and base station setups. At 3 metres length the lead balances reach and attenuation suitable for short runs where minimal loss and ease of handling are important.

Suitable for

• Connecting amateur radio transceivers to external antennas or antenna tuners
• CB radio installations in vehicles or fixed locations
• Linking VHF/UHF equipment, scanners and handheld radio accessories to a UHF socket
• Temporary test setups and short-range RF patching on workbenches

Key specifications

• Cable type: RG58 coaxial
• Impedance: 50 ohm
• Connector A: Mini UHF (male)
• Connector B: SO239 UHF (female socket)
• Length: 3 metres
• Typical application: VHF/UHF and CB radio frequency transmission

How to use

Align the Mini UHF male connector with the mating UHF female or adapter and push in until the connector seats; secure the SO239 socket by threading it onto the mating PL259 or fixed UHF plug if applicable. Ensure connections are hand‑tight and avoid excessive torque to prevent mechanical damage to connector threads. Route the cable to minimise sharp bends and avoid kinking; keep it clear of high‑voltage power lines and sources of electromagnetic interference to preserve signal quality.

Usage recommendations

For best RF performance, use this 3 m RG58 lead for short interconnections where low attenuation and flexibility are required. If longer runs or lower loss are necessary, consider a larger diameter coaxial cable with lower attenuation. Inspect connectors periodically for corrosion or loose contacts, and replace the lead if shielding or insulation shows wear.
