Coaxial cable Rangeful HF240-SM-PL-2 — 50 Ω, PL259 (UHF) to SMA male, 2 m

Rangeful HF240-SM-PL-2 is a 2 m coaxial RF cable with 50 Ω characteristic impedance, terminated with a PL259 (UHF) connector on one end and an SMA male on the other. It is designed to provide a reliable, low-loss connection between radio transceivers, antennas and test equipment where 50 Ω matching is required. The cable's length and connector combination make it suitable for both temporary field use and fixed installations that need a compact, flexible RF link.

Advantages

This 50-ohm cable offers straightforward compatibility with common amateur radio, commercial radio and laboratory equipment. The PL259 (UHF) connector provides a robust screw-on connection for equipment with SO-239 or UHF sockets, while the SMA male fits precision RF ports on transceivers, routers and test instruments. The two-meter length balances reach and signal integrity, minimizing insertion loss compared with longer runs and keeping installations tidy. The construction reduces reflections and maintains impedance continuity for consistent RF performance.

Suitable for

• Connecting transceivers or radios to antennas with mismatched connector types
• Laboratory and bench testing of RF devices with 50 Ω ports
• Temporary or portable field setups for amateur radio and communications
• Integration between routers, modems or radio front-ends that use SMA and UHF connections

Key specifications

• Characteristic impedance: 50 Ω
• Length: 2 meters
• Connector A: PL259 (UHF) male
• Connector B: SMA male
• Cable type: coaxial RF cable suitable for general-purpose 50 Ω applications
• Typical use: RF signal transmission between transceivers, antennas and test equipment

How to use

Connect the PL259 end to the corresponding UHF socket (SO-239) by aligning the connector and securing the threaded coupling to ensure a firm mechanical and electrical contact. Attach the SMA male end by gently seating and tightening it into the SMA female port until hand-tight; avoid excessive torque to prevent damage to the connectors. Route the cable to avoid sharp bends and kinks, and keep it away from strong EMI sources where possible. For temporary setups, verify continuity and SWR on the connected equipment after installation.

Usage recommendations

Inspect connectors regularly for wear or corrosion, especially after outdoor or portable use. For measurements requiring the lowest possible loss, minimize cable length and use high-quality adapters if conversion to other connector types is necessary. Store the cable coiled without tight loops to maintain cable integrity and consistent RF performance.
