Coaxial cable Rangeful HF240, BNC male to PL259 UHF, 50 Ω, 7 m

Rangeful HF240 coaxial cable with BNC male to PL259 UHF connectors is a 7 m, 50 Ω cable designed for HF and VHF radio and antenna connections. The cable provides a flexible link between equipment using a BNC male plug and devices or antennas with a PL259 (UHF) socket, maintaining impedance matching for transmissions in amateur radio, scanners and CB installations. Its fixed length and standardized connectors make it a ready-to-use solution for setups that require reliable RF signal transfer over short to medium runs.

Advantages

The cable combines a 50 Ω characteristic impedance with BNC male and PL259 UHF connectors to ensure consistent RF performance and impedance continuity. Its 7 m length offers flexibility for arranging transceivers, scanners or antenna hardware while avoiding unnecessary cable slack. The construction balances flexibility and durability for routine handling and installation. Connectors are widely compatible with legacy and common radio equipment, simplifying integration into existing systems.

Suitable for

• Amateur (ham) radio transceivers and external antennas
• VHF/UHF scanners and monitoring receivers
• CB radio setups requiring UHF (PL259) connections
• Temporary or permanent antenna feedlines where a BNC-to-PL259 interface is needed

Key specifications

• Impedance: 50 Ω
• Length: 7 m
• Connector A: BNC male
• Connector B: PL259 (UHF) male
• Intended frequency range: HF and VHF bands (suitable for typical amateur, scanner and CB frequencies)
• Cable type: flexible coaxial cable for RF applications

How to use

Inspect connectors and cable for visible damage before use. Firmly screw the PL259 connector to a matching SO-239 socket and push-and-twist the BNC male into a BNC female jack until it locks. Ensure both ends are fully seated and that there is no strain or sharp bends near the connectors. Route the cable to avoid kinks, high-tension points or proximity to large electrical noise sources. After installation, perform an operational check using your radio or scanner to confirm transmit and receive performance and, when possible, verify VSWR or signal levels using appropriate test equipment.

Usage recommendations

For best long-term performance, avoid repeated sharp bending near the connectors, protect connectors from moisture and corrosion, and use proper strain relief at attachment points. If precise matching or low-loss performance is critical at higher frequencies, consider measuring VSWR and, if necessary, using a purpose-built low-loss feedline or antenna tuner.
