Coaxial Cable Rangeful HF400-BNCM-PL-7 50 Ω, 7 m — BNC Male to PL259 UHF

The Rangeful HF400-BNCM-PL-7 is a 7-meter coaxial cable with 50 Ω characteristic impedance, terminated with a BNC male connector on one end and a PL259 (UHF) connector on the other. It is intended for RF and HF signal transmission where a flexible, shielded cable with reliable mechanical coupling is required. The cable is suitable for linking equipment that uses BNC and PL259 interfaces, ensuring impedance-matched connections for transceivers, antennas and measurement devices.

Advantages

This coaxial cable offers a consistent 50 Ω impedance along its length to minimize reflections and preserve signal integrity in HF and VHF frequency ranges. The BNC male connector provides a quick, bayonet-style coupling while the PL259 (UHF) connector delivers a threaded, mechanically secure connection for radios and antenna feedlines. The 7 m length gives added reach for flexible placement of radios, antennas or test instruments without requiring multiple adapter joints.

Suitable for

• Connecting amateur radio transceivers to antennas or antenna tuners
• Linking test equipment such as signal generators and spectrum analyzers to devices under test
• Temporary or semi-permanent station wiring where BNC-to-PL259 interfaces are present

Key specifications

• Characteristic impedance: 50 Ω
• Cable length: 7 m
• Connector A: BNC male (bayonet coupling)
• Connector B: PL259 (UHF) male (threaded coupling)
• Cable type: coaxial with shielding for RF use

How to use

Ensure all equipment is powered down before making connections. Align the BNC male connector with the BNC female socket and engage the bayonet until it snaps into place. Thread the PL259 connector onto the corresponding SO‑239 or UHF female socket and tighten by hand; if required, use a suitable wrench to secure the connection without over‑tightening. Route the cable to avoid sharp bends, kinks and proximity to strong noise sources. After connecting, verify continuity and SWR as appropriate for the application.

Usage recommendations

For best long‑term performance, avoid repeated sharp flexing near the connectors, keep the cable dry and protected from prolonged UV exposure, and inspect connectors periodically for corrosion or loose fittings. When using with high‑power transmitters, monitor temperature at connectors and consider using additional strain relief or support for the cable run.
