Coaxial cable SMA male to PL259 UHF for RG58/U, Rangeful, 50 Ω, 0.5 m

Coaxial cable SMA male to PL259 UHF for RG58/U, Rangeful, 50 Ω, 0.5 m is a short RF adapter cable that connects equipment with an SMA male connector to devices using a PL259 (UHF) socket. Designed for RG58/U coaxial cable construction and 50 ohm impedance, this 0.5 meter cable provides a compact, low-loss link for antenna feeds, radio transceivers and test instruments where reliable RF continuity and simple mating between connector types are required.

Advantages

This adapter cable offers low insertion loss suitable for short interconnects, mechanical compatibility between SMA and PL259 interfaces, and a standardized 50 Ω impedance that preserves signal integrity in typical RF systems. The flexible RG58/U construction balances bendability and shielding for use in tight installations, while the short 0.5 m length minimizes cable attenuation and reduces the chance of signal reflections in near-field connections.

Suitable for

• Connecting handheld or bench radios with SMA output to PL259 antenna leads
• Linking test equipment and measurement devices that require a PL259 input
• Temporary or permanent antenna feedlines in ham radio and VHF/UHF setups
• Lab and field RF experiments where short, low-loss jumper cables are needed

Key specifications

• Connector types: SMA male to PL259 (UHF)
• Cable type: RG58/U coaxial construction
• Impedance: 50 Ω
• Length: 0.5 m
• Typical use: RF and antenna interconnects, radio equipment and test setups

How to use

Connect the SMA male end to the SMA female socket on the transmitter, receiver or adapter, ensuring the threaded coupling is engaged and hand-tightened without excessive torque. Attach the PL259 end to the matching SO-239 or PL259 connector on the antenna cable, radio chassis or test instrument by aligning and fastening the UHF connection securely. Route the cable to avoid sharp bends and electromagnetic interference sources; the short length is intended for close-proximity connections where minimal loss is important.

Usage recommendations

For best performance, use the cable for short runs only and avoid tight bending radii near the connector ends. Inspect connectors periodically for corrosion or loose coupling, and replace the cable if shielding or insulation is visibly damaged. When used with sensitive measurement equipment, verify connection integrity and perform baseline measurements to account for any insertion loss.
