Coaxial cable Rangeful HF240-SM-PL-15 15 m 50 Ω with PL259 (UHF) to SMA male connectors

Coaxial cable Rangeful HF240-SM-PL-15 is a 15-meter, 50 Ω RF cable terminating in a PL259 (UHF) connector at one end and an SMA male connector at the other. It is developed for connecting radios, antennas and RF devices where a PL259–SMA interface is required. The cable construction maintains impedance matching across the length to reduce reflections and preserve signal integrity for medium-distance runs between transceivers, scanners and laboratory equipment.

Advantages

The cable provides a standardized 50-ohm impedance for consistent RF performance and lower VSWR compared with mismatched leads. Its 15 m length offers flexibility for antenna placement and test bench layouts without needing additional adapters. The combination of a PL259 (UHF) connector and an SMA male connector enables direct connection between legacy equipment that uses UHF connectors and modern devices with SMA ports. The cable design balances flexibility and shielding to limit interference while remaining manageable during installation.

Suitable for

• Amateur radio stations and transceivers requiring PL259 to SMA connection
• Scanner receivers and monitoring equipment
• Antenna feeds for medium-distance indoor or field setups
• RF test benches and measurement setups with mixed connector types
• Temporary or semi-permanent installations where a 15 m lead is appropriate

Key specifications

• Impedance: 50 Ω
• Length: 15 m
• Connector 1: PL259 (UHF) male
• Connector 2: SMA male
• Application: RF signal transmission for radio, antenna and test equipment

How to use

Connect the PL259 end to the device or antenna with a corresponding UHF female socket, and attach the SMA male end to the receiver, transceiver or measurement instrument with an SMA female port. Ensure connectors are aligned and hand-tighten where applicable; avoid excessive torque to protect threads and center pins. Route the cable to minimize sharp bends and keep it clear of high-power AC lines and strong RF sources that can introduce interference. For permanent runs, secure the cable with appropriate clips or ties at intervals to prevent strain on connector joints.

Usage recommendations

Inspect connectors before use for debris or damage, and verify tight but not over-tightened connections. For outdoor or prolonged exposure, consider additional weatherproofing at connector interfaces. When using for measurements, keep cable length and routing consistent to reduce variability in results.
