Coaxial adapter cable Rangeful Mini UHF (Male) to SO239 UHF (50 Ω) RG58, 1 m

Rangeful Mini UHF (Male) to SO239 UHF (50 Ω) RG58, 1 m is a coaxial adapter cable designed to connect devices that use a compact Mini UHF (also called Mini-UHF or M-UHF) male plug to equipment with a standard SO239 UHF socket. Built on RG58 coaxial cable with nominal 50 ohm impedance and a one-meter length, this adapter provides a straightforward, low-profile link for RF and radio applications where space is limited but consistent 50 Ω signal transfer is required.

Advantages

This adapter cable combines a compact Mini UHF male connector with a full-size SO239 UHF socket on a flexible RG58 dielectric, ensuring mechanical compatibility between different connector families while preserving 50 Ω electrical characteristics. The one-meter length offers manageable reach for patching and short runs without excessive signal loss typical of longer leads. The cable is suitable for tight installations due to the smaller Mini UHF plug profile and allows quick mating to standard SO239 sockets commonly found on transceivers, scanners, and antenna systems.

Suitable for

• Connecting handheld or compact radio equipment with Mini UHF male outputs to devices with SO239 sockets
• Short patch leads between transceivers, scanners, and antenna tuners
• Amateur radio setups where a compact plug needs to interface with standard UHF sockets
• Temporary test connections and bench work in RF troubleshooting

Key specifications

• Cable type: RG58 coaxial
• Characteristic impedance: 50 Ω
• Connector A: Mini UHF male (compact UHF plug)
• Connector B: SO239 UHF socket (50 Ω UHF receptacle)
• Length: 1 meter
• Typical use: RF/interconnect for VHF/UHF bands and general-purpose 50 Ω systems

How to use

Align the Mini UHF male plug with the mating socket on the compact radio or accessory and push until the connector seats. For the SO239 socket, guide the plug into the threaded receptacle and secure as required by the mating connector type. Use the cable for short interconnections only; avoid tight bends at the connector transition and do not subject the cable to repeated sharp flexing. Ensure both ends are clean and free from debris before mating to reduce the risk of poor contact or signal degradation.

Usage recommendations

Use this adapter for short, low-loss connections in 50 Ω RF systems such as amateur radio rigs, scanners, and bench testing setups. Avoid extended outdoor exposure without weather protection and do not use as a permanent exterior feedline. For runs longer than a few meters or installations requiring minimal insertion loss, consider a heavier coax type or a purpose-built feedline.
