Coaxial cable Rangeful Mini UHF (Male) to SO239 UHF, RG58 50 Ω, 12 m

Coaxial cable Rangeful Mini UHF (Male) to SO239 UHF, RG58 50 Ω, 12 m is a 12-meter RF lead built on RG58 coaxial with nominal 50 ohm impedance. The cable terminates with a Mini UHF (male) connector on one end and an SO239 UHF socket on the other, providing a flexible connection for RF equipment. It is intended for short-to-medium length runs where reliable impedance matching and standard UHF-style connectors are required for transmitting VHF/UHF signals and test signals.

Advantages

The RG58 construction delivers a balance of flexibility and signal integrity appropriate for installations where routing and movement are common. The Mini UHF (male) to SO239 interface enables compatibility between devices that use the smaller Mini UHF plug and equipment or antenna mounts fitted with a SO239 socket. The 12 m length offers extended reach without excessive attenuation for many amateur radio, scanner, and test applications. The cable’s 50 Ω impedance supports standard RF systems and reduces mismatch loss when used with matching 50 Ω equipment.

Suitable for

• Amateur radio transceivers and handheld-to-base connections
• Scanner receivers and short antenna feeds
• Temporary test setups and laboratory RF measurements
• Antenna tuning and extension for VHF/UHF applications

Key specifications

• Coaxial type: RG58
• Impedance: 50 Ω
• Length: 12 m
• Connector A: Mini UHF (male)
• Connector B: SO239 UHF (socket)
• Cable flexibility: standard RG58 flexible jacket
• Typical use: VHF/UHF signal transmission and testing

How to use

Connect the Mini UHF (male) end to the corresponding Mini UHF socket on your device and thread the SO239 connector onto the mating PL259 or antenna mount. Ensure connectors are snug but avoid excessive force when tightening. Route the cable to minimize sharp bends and keep it away from strong sources of electrical noise. For measurement or testing, verify that both connected devices are configured for 50 Ω systems to maintain proper impedance matching and reduce reflection losses.

Usage recommendations

For optimal performance, avoid tight bends with radii smaller than recommended for RG58 cable and protect connectors from moisture and mechanical strain. Use short jumper lengths where possible to limit loss at higher frequencies, and inspect connectors periodically for corrosion or loose contacts. When connecting to outdoor antennas, apply appropriate weatherproofing to the SO239 connection.
