Coaxial cable Rangeful HF400 SMA Male to SMA Female 50 Ω 25 m

Rangeful HF400 coaxial cable with SMA male to SMA female connectors is a 25 m, 50 Ω RF transmission cable designed for applications requiring SMA interfaces. The cable uses HF400 construction to provide consistent characteristic impedance over long runs and maintain signal integrity for antenna connections, test setups and radio equipment links. Flexible jacketing allows easier routing while preserving electrical performance across the cable length.

Advantages

The HF400 cable construction offers a balance of flexibility and stable electrical characteristics, keeping return loss low and minimizing signal reflections across the 50 Ω transmission line. SMA male to SMA female connectors provide a compact, threaded interface for secure mating with compatible devices. The 25 m length supports extended runs without the immediate need for inline amplifiers or repeaters in many low-power RF setups.

Suitable for

• Antenna connections for routers, modems and external antennas
• Laboratory test setups and measurement rigs requiring SMA interfaces
• Short-range radio equipment links and amateur radio applications
• Signal routing in RF systems with 50 Ω impedance

Key specifications

• Impedance: 50 Ω
• Length: 25 m
• Connector configuration: SMA male to SMA female
• Cable type: HF400 coaxial
• Characteristic: flexible jacket for routing

How to use

Connect the SMA male end to the SMA female port on the transmitting device and the SMA female end to the receiving device or antenna, ensuring threads are engaged by hand and tightened to a snug fit without over-torquing. Avoid sharp bends and kinks along the cable run; maintain a bend radius appropriate for HF400-type coax to preserve impedance consistency. For outdoor installations, protect connectors and exposed cable with weatherproofing materials and appropriate strain relief.

Usage recommendations

Regularly inspect connectors for corrosion or damage and replace any section showing mechanical wear. Keep cable runs separated from high-power AC wiring to reduce potential interference. For critical measurements, use the shortest practical cable length and verify system performance with known-good test equipment.
