Coaxial cable Rangeful PL259 UHF to SMA RG58/U 50 Ω 1 m

Rangeful coaxial cable PL259 UHF to SMA RG58/U 50 Ω, 1 m, is a flexible RF interconnection cable intended for linking equipment with UHF (PL259) and SMA connectors. Built on RG58/U 50 ohm coaxial geometry, this 1-metre cable provides the impedance matching and mechanical fit commonly required for amateur radio stations, antenna feeders, test instruments and other RF devices that use these connector types.

Advantages

The cable combines a durable PL259 (UHF) connector on one end and a compact SMA connector on the other to enable mating between legacy and modern RF equipment. Using RG58/U 50 Ω coax ensures standard characteristic impedance for stable signal transfer up to typical VHF/UHF frequencies where RG58 performance is appropriate. The 1 m length offers a convenient balance of flexibility and minimal signal loss for short links, and the construction supports straightforward hand-assembly connections between transceivers, antennas, and measurement devices.

Suitable for

• Connecting amateur radio transceivers to antennas or antenna switch boxes
• Linking radios or transceivers with SMA-equipped accessories or adapters
• Laboratory and field testing where UHF-to-SMA connectivity is required
• Integrating legacy PL259-equipped equipment with newer SMA-interface modules

Key specifications

• Coaxial type: RG58/U
• Characteristic impedance: 50 Ω
• Connector A: PL259 (UHF male)
• Connector B: SMA male
• Length: 1 m
• Typical application frequency range: VHF/UHF bands (subject to system requirements)
• Construction: flexible coax with soldered/crimped connector terminations

How to use

Connect the PL259 end to the mating UHF (SO-239) socket and the SMA end to the corresponding SMA jack, ensuring threaded connectors are fully engaged but not over-tightened. Route the cable to avoid sharp bends and prolonged compression that could deform the dielectric or shield. For test setups, keep the cable length as short as practical to minimise insertion loss and reflections; inspect connectors for secure seating and clean contact surfaces when required.

Usage recommendations

Use this RG58/U 50 Ω cable for short interconnects within radio racks, portable setups and test benches. Avoid using it as a long run for high-UHF or microwave frequencies where low-loss coax types are preferred. Periodically check connector integrity and protect exposed connectors from moisture and mechanical strain to maintain signal quality.
