Coaxial Cable 50 Ohm, Rangeful HF400 N Male to N Female, 25 m

Rangeful HF400 N Male to N Female coaxial cable, 25 m long, offers a pre-terminated 50 ohm feedline for RF signal transmission, antenna connections and test setups. The cable assembly uses HF400-type coaxial construction with N male and N female connectors fitted to each end, providing a fixed-length solution that simplifies installation for amateur radio, base station and laboratory environments where a reliable 50 Ω connection is required.

Advantages

The cable delivers consistent 50 ohm impedance across its length to minimise VSWR-related losses and ensure stable RF performance. Durable outer jacket and HF400 dielectric structure provide resistance to bending and mechanical wear while maintaining signal continuity. Factory-terminated N connectors ensure repeatable mating and secure threaded connections compatible with standard N-series interfaces. The 25 m length allows flexible placement of antennas or equipment without additional on-site termination work.

Suitable for

• Amateur (ham) radio station feedline between transceiver and antenna
• Fixed base station and repeater RF connections
• Laboratory test setups and measurement links
• Temporary field deployments and antenna testing where a pre-terminated cable is needed

Key specifications

• Characteristic impedance: 50 Ω
• Length: 25 m
• Connector type: N male to N female
• Cable type: HF400-style coaxial construction
• Outer jacket: durable protective sheath for mechanical protection
• Intended frequency use: RF and microwave ranges compatible with HF400 characteristics

How to use

Connect the N male and N female connectors to the corresponding N-series sockets on transceivers, antennas or test equipment. Ensure threads are engaged fully and hand-tighten; use a torque wrench or spanner only if the equipment documentation recommends a specific torque to avoid over-tightening. Route the cable to minimise sharp bends and avoid kinks; maintain the recommended bend radius for HF400-type coax to preserve electrical performance. Verify connector seating and continuity before powering RF amplifiers or transmitting to prevent mismatch-related issues.

Usage recommendations

Inspect connectors periodically for corrosion or debris and keep the threaded interfaces clean and dry. For outdoor use, protect connector interfaces with suitable weatherproofing materials and secure the run to prevent strain on the connectors. When used in sensitive measurement setups, check insertion loss and VSWR with test equipment after installation to confirm expected performance.
