Coaxial cable Rangeful HF240-SM-PL-1 — 1 m, 50 Ω, PL259 (UHF) to SMA male

Rangeful HF240-SM-PL-1 is a 1 m coaxial cable with 50 Ω impedance, fitted with a PL259 (UHF) connector on one end and an SMA male connector on the other. The cable is intended for RF signal connections between devices that use UHF and SMA interfaces. It provides a short, low-loss connection suitable for linking amateur radio transceivers, scanners, and test equipment where matching to 50 ohms is required.

Advantages

The HF240-SM-PL-1 delivers consistent 50 Ω impedance along its length to minimize reflections and standing waves. Its PL259 and SMA male terminations ensure mechanical compatibility with common UHF and SMA sockets. At 1 metre length it offers a compact patch solution with reduced signal degradation compared to longer runs and is convenient for bench setups and temporary connections.

Suitable for

• Amateur radio transceiver to antenna tuner or patch connections
• Scanner and receiver connections requiring UHF-to-SMA adaptation
• RF test setups and measurement rigs with mixed connector types
• Short indoor patch leads between equipment in a radio shack or lab

Key specifications

• Impedance: 50 Ω
• Length: 1 m
• Connector A: PL259 (UHF), male
• Connector B: SMA, male
• Intended use: RF signal transmission, short patch connections

How to use

Ensure both mating connectors are free of debris and that equipment is powered down or set to a safe state before connecting. Screw the SMA male connector carefully into the SMA female socket until snug; avoid over-tightening. Align the PL259 with the corresponding UHF socket and secure it according to the socket’s fastening method. Use the cable for short runs where minimal insertion loss and correct 50 Ω matching are required. After use, store the cable coiled without sharp bends to preserve connector integrity and cable performance.

Usage recommendations

For best RF performance, avoid routing the cable near strong sources of interference and keep length as short as practical for the application. Inspect connectors periodically for wear, and replace the cable if physical damage or degraded connectivity is observed.
