Coaxial cable N Male to N Female Rangeful HF400, 50 Ω, flexible HF cable, 30 m

Rangeful HF400 coaxial cable with N male to N female connectors is a 30 m, 50 Ω flexible RF cable designed for low-loss signal transmission between devices with N-type ports. The cable combines a robust outer jacket and a high-quality centre conductor to maintain impedance stability and consistent performance across commonly used RF bands. It is intended for antenna feeds, test bench connections and installations where a durable, pliable coaxial link is required.

Advantages

The flexible HF400 construction offers a balance of mechanical durability and bendability, facilitating routing in confined or complex installations while preserving RF integrity. N-type male and female connectors provide secure, threaded connections with good shielding to minimise connector-related losses. The 50 Ω impedance supports compatibility with standard RF equipment, reducing reflections and maintaining signal quality over the cable length.

Suitable for

• Antenna feed lines for amateur and professional radio
• RF test and measurement setups on benches
• Connecting transceivers, amplifiers and RF instruments with N-type ports
• Temporary or permanent installations requiring a flexible low-loss coaxial link

Key specifications

• Characteristic impedance: 50 Ω
• Cable type: HF flexible coaxial (solid centre conductor with braided shield)
• Length: 30 m
• Connector configuration: N male to N female
• Jacket: weather-resistant outer sheath suitable for indoor and short-term outdoor use
• Frequency: suitable for a wide range of RF frequencies used in amateur and professional systems
• Electrical performance: designed for low insertion loss and stable impedance

How to use

Connect the N male end to the device or antenna with the corresponding N female socket and tighten the threaded coupling by hand, then secure with a torque wrench if specified by the connected equipment to ensure proper mating and shielding. Route the cable avoiding sharp bends and tight radii to prevent deformation of the inner conductor and maintain consistent impedance. For outdoor segments, position the cable to minimise prolonged UV exposure and standing water; use additional sealing or conduit where long-term weather resistance is required.

Usage recommendations

For optimal RF performance, avoid kinking the cable and maintain recommended bend radius; use strain relief and proper grounding where applicable. When used outdoors, protect connector joints with appropriate tape or covers to reduce moisture ingress. Verify connector torque and inspect for corrosion periodically in humid or coastal environments.
