Coaxial cable Rangeful HF240-SM-PL-0.5, 50 Ω, 0.5 m, PL259 (UHF) to SMA male

This Rangeful HF240-SM-PL-0.5 coaxial cable is a 0.5 m, 50 Ω RF cable assembly with a PL259 (UHF) connector on one end and an SMA male on the other. It is designed for reliable RF signal transmission between equipment that uses UHF (PL259) and SMA interfaces. The short length minimizes insertion loss and reflections, making it suitable for compact radio setups, antennas, adapters and test instruments where a low-loss, direct connection is required.

Advantages

The cable provides a consistent 50 Ω impedance for stable RF performance across common VHF and UHF frequency ranges. The PL259 connector offers a secure screw-on connection to UHF sockets while the SMA male end ensures precise mating with SMA female ports. At 0.5 m length the assembly reduces signal attenuation compared with longer leads and simplifies cable routing in tight spaces. The construction balances flexibility and durability for repeated connections and repositioning.

Suitable for

• Connecting transceivers and handheld radios to external antennas
• Interfacing antenna bases or adapters with SMA-equipped equipment
• Bench testing and measurement where short, low-loss RF leads are needed
• Portable or mobile installations with limited space for cabling

Key specifications

• Characteristic impedance: 50 Ω
• Cable length: 0.5 m
• Connector A: PL259 (UHF, screw-on)
• Connector B: SMA male
• Typical use: RF signal transmission between UHF and SMA interfaces

How to use

Align the PL259 connector with the corresponding UHF socket and thread it on until hand-tight to ensure a secure mechanical and electrical connection. Insert the SMA male into the SMA female port and secure by hand if applicable; avoid excessive torque on the SMA to prevent damage. Route the 0.5 m cable to minimize sharp bends and avoid tight kinks; maintain gentle bend radii to preserve cable integrity. Perform basic continuity or SWR checks after installation when used in antenna systems or RF test setups.

Usage recommendations

For best performance, keep the cable length as short as practical and avoid coiling tightly. When connecting to sensitive test equipment, inspect connectors for dirt or damage and ensure clean, dry mating surfaces. If repeated mating cycles are expected, consider periodic inspection of connector threads and SMA center pin to maintain reliable contact.
