Coaxial Cable Rangeful SMA (male) to PL259 UHF RG58/U 50 Ω, 7 m

Rangeful 7-meter coaxial cable with SMA (male) to PL259 UHF connectors is built on RG58/U construction with 50 Ω impedance. The cable is intended for RF connections between devices that use SMA and PL259 interfaces, delivering standard RG58 flexibility and impedance matching for effective signal transfer over a moderate length. It is suitable for amateur radio, scanners, portable transceivers and test setups where a 50 ohm link and common connector types are required.

Advantages

This RG58/U coaxial assembly combines a compact SMA male connector with a PL259 UHF plug to link differing RF equipment without adapters. At 7 meters length it provides extended reach while maintaining the characteristic 50 Ω impedance for minimized mismatch loss. The cable maintains typical RG58 flexibility for routing in tight spaces and offers reliable mechanical connections for repeated use in field or bench conditions.

Suitable for

• Amateur radio stations connecting transceivers to external antennas or tuners
• Scanner receivers and monitoring equipment requiring PL259 to SMA adaptions
• Portable and mobile radio setups where a 7 m cable run is needed
• Laboratory and test equipment interconnects for RF measurements

Key specifications

• Cable type: RG58/U coaxial
• Impedance: 50 ohm
• Connector A: SMA male
• Connector B: PL259 (UHF) plug
• Length: 7 meters
• Typical use: RF signal transmission, low- to mid-frequency applications
• Mechanical: flexible jacket suitable for routing and field deployment

How to use

Connect the SMA male end to the SMA female port on the radio, antenna or adapter, and attach the PL259 plug to the corresponding UHF socket. Ensure connectors are fully seated and, where applicable, hand-tighten the SMA and tighten the PL259 coupling to secure the mechanical and electrical contact. Route the cable to avoid sharp bends and excessive strain; allow a gradual curve radius consistent with RG58 flexibility. For measurement setups, confirm impedance continuity and check for stable RF readings after installation.

Usage recommendations

Store the cable coiled without tight loops and avoid repeated flexing at the connector junctions. For best RF performance, minimize the number of additional adapters and keep the cable length as short as practical for the application. Inspect connectors periodically for corrosion or wear and replace the cable if the jacket or shielding is damaged.
