Coaxial cable Rangeful HF400 Male SMA to Male N, 50 Ω, flexible HF400, length 20 m

Coaxial cable Rangeful HF400 Male SMA to Male N, 50 Ω, flexible HF400, length 20 m provides a flexible, 50-ohm RF connection between SMA and N male interfaces. The cable is designed for reliable signal transmission in antenna feeds, test setups and equipment interconnects where low-loss flexible coax is required. Its 20 m length allows installation across longer runs while maintaining consistent impedance and connector compatibility with common RF devices.

Advantages

The flexible HF400 construction offers a balance of mechanical flexibility and electrical performance suitable for routing in constrained spaces. With male SMA and male N connectors on each end, the cable enables direct mating to devices and antennas using standard interfaces without adapters. Consistent 50 Ω impedance throughout the cable minimizes reflections and ensures predictable RF behaviour across typical communication and measurement frequencies. The 20 m length reduces the need for multiple cable joins, which can introduce loss or mismatch.

Suitable for

• Connecting RF test instruments and spectrum analysers to devices with SMA or N ports
• Antenna feeds for base stations, routers, and outdoor antenna systems
• Amateur radio station interconnects and mobile setups
• Temporary or semi-permanent installations where flexibility and standard connectors are required

Key specifications

• Characteristic impedance: 50 Ω
• Connector A: Male SMA
• Connector B: Male N
• Cable type: HF400 flexible coax
• Length: 20 m
• Typical use: RF signal transmission between devices and antennas

How to use

Route the cable between equipment ensuring minimal sharp bends and avoiding tight kinks; maintain bend radii recommended for flexible coax to prevent damage and preserve impedance. Secure connectors by hand-tightening the SMA and N male ends to their mating female ports; for N connectors, use a torque wrench if a specific torque value is required by the equipment manual. Avoid excessive pull or strain on the cable near the connector junctions and use appropriate cable clamps or strain relief where needed.

Usage recommendations

For best RF performance, keep the cable run as short as practical, avoid close parallel runs with power cables to reduce interference, and inspect connectors for dirt or corrosion before connecting. If used outdoors or in harsh environments, protect connectors from moisture with suitable sealing tape or boots and periodically check the cable for abrasion or crushing along the run.
