Coaxial cable Rangeful HF400-SM-PL-7 — SMA Male to PL259 UHF, 7 m, HF400, 50 Ω, full copper

The Rangeful HF400-SM-PL-7 coaxial cable links an SMA male connector to a PL259 (UHF) connector over a 7 meter length. Constructed on HF400 coax with a characteristic impedance of 50 Ω and full-copper conductors, this cable is intended for HF and VHF signal transmission where low loss and reliable shielding are important. It is compatible with radio transceivers, antenna connections, base stations and test setups requiring an SMA-to-PL259 interface and a robust, flexible RF lead.

Advantages

This cable combines HF400 coax construction with full-copper conductors to provide consistent electrical continuity and low insertion loss across HF and VHF bands. The 50 Ω impedance matches standard radio equipment, reducing VSWR-related signal degradation. The SMA male and PL259 (UHF) connectors offer secure mechanical mating for common transceivers and antenna systems. A 7 m length allows flexible placement of equipment while maintaining a single continuous RF path.

Suitable for

• Connecting transceivers and radios with SMA male outputs to antennas or devices using PL259 (UHF) inputs
• Amateur radio stations and base station antenna feeds
• HF and VHF testing setups and temporary installations
• Radio equipment configurations requiring a 50 Ω cable with full-copper conductors

Key specifications

• Cable type: HF400 coax
• Connectors: SMA male to PL259 (UHF)
• Length: 7 m
• Impedance: 50 Ω
• Conductor material: full copper
• Application bands: HF and VHF frequency ranges

How to use

Inspect connectors and cable for visible damage before use. Securely hand-tighten the SMA male connector onto the mating SMA jack and fasten the PL259 connector to the corresponding UHF socket, ensuring correct thread engagement and firm contact. Route the cable to avoid sharp bends and mechanical strain on connectors; maintain a bend radius appropriate for HF400 coax. For temporary test setups, place the cable clear of sources of interference and mechanical hazards. After installation, verify continuity and check SWR or signal levels on the radio equipment to confirm proper operation.

Usage recommendations

Store the cable coiled without tight loops and protect connectors with caps when not in use. Avoid prolonged exposure to moisture and direct sunlight; if outdoor use is required, provide additional environmental protection at connector junctions. Periodically inspect connector contacts and re-tighten fittings as needed to maintain optimal RF performance.
