UHF coaxial cable Rangeful PL259 to PL259 HF400 flexible 50 Ω, 7 m

Rangeful UHF coaxial cable HF400 with PL259 connectors on both ends is a 7 m, 50 Ω RF cable designed for HF, VHF and UHF radio systems. The HF400 flexible construction enables easier routing and placement in both portable and fixed setups while maintaining consistent impedance for transceivers, antennas and other RF equipment that use standard UHF (PL259) terminations.

Advantages

The cable combines standard PL259 terminations with a flexible HF400 dielectric and braid to reduce signal loss over short to moderate runs. Its 50 Ω characteristic impedance matches common amateur and professional radio equipment. Flexibility of the HF400 jacket and braid allows simpler installation in constrained spaces and reduces stress on connectors during movement or repositioning.

Suitable for

• Connections between transceivers and antennas in HF, VHF and UHF bands
• Portable radio stations and field operation where flexibility is required
• Fixed installations where standard PL259 terminations are used
• Testing and bench setups for RF equipment with UHF (PL259) sockets

Key specifications

• Connector type: PL259 to PL259 on both ends
• Characteristic impedance: 50 Ω
• Cable type: HF400 flexible coaxial construction
• Length: 7 m
• Application bands: HF, VHF, UHF

How to use

Ensure both mating connectors (SO-239 or other UHF female sockets) are clean and free of debris before making connections. Hand-tighten the PL259 connectors to the corresponding sockets until secure; avoid excessive force to prevent damage to the connector threads. Route the cable to avoid sharp bends with radii smaller than the cable's natural curvature and keep it away from sources of strong electromagnetic interference where possible. For mobile installations, secure the cable to prevent repeated flexing at the connector interface.

Usage recommendations

Use the cable for runs where a combination of standard PL259 terminations and improved flexibility is needed. For longer runs or higher-frequency applications where lower loss is critical, consider evaluating alternative cable types with lower attenuation. Periodically inspect connectors for corrosion and mechanical wear, and replace the cable if the braid or dielectric shows signs of damage.
