Coaxial cable Rangeful HF400-NM-SM-25 25 m, SMA Male to N Male, UltraFlex HF400

Rangeful HF400-NM-SM-25 is a 25 m coaxial cable assembly with an SMA male connector at one end and an N male connector at the other. Built on HF400 UltraFlex dielectric, the cable offers a reduced bend radius and improved handling compared with standard RF coax. It is designed for RF signal connections between devices with SMA and N interfaces, suitable for test benches, antenna feeds and field instrumentation where a longer, flexible RF lead is required.

Advantages

The HF400 UltraFlex construction provides enhanced flexibility and easier routing in cramped or mobile installations while maintaining consistent characteristic impedance and shielding for reliable signal transfer. The combination of SMA male and N male connectors supports mating with common lab instruments, antennas and communication equipment. The 25 m length reduces the need for additional adapters or multiple shorter cables and is intended to preserve signal integrity across moderate distances.

Suitable for

• Connecting test equipment and signal generators to devices with N-type or SMA interfaces
• Temporary or semi-permanent antenna installations where flexibility is required
• Field measurements and mobile communication setups
• Laboratory measurements and RF bench setups

Key specifications

• Cable type: coaxial with HF400 UltraFlex dielectric
• Length: 25 m
• Connector A: SMA male
• Connector B: N male
• Characteristic impedance: 50 Ω
• Typical frequency range: suitable for RF and microwave test applications (consult system requirements for specific frequency limits)
• Flexible construction for reduced minimum bend radius

How to use

Inspect connectors and cable for damage before use. Align SMA male and N male connectors with the mating ports and hand-tighten the connector interfaces; use a torque wrench set to the manufacturer's recommended torque if high repeatability is required. Route the cable to avoid sharp bends, crushing or kinks and keep it clear of high-voltage lines and strong sources of electromagnetic interference. For best performance, minimize unnecessary cable length and avoid coiling tightly during operation.

Usage recommendations

Store the cable loosely coiled and protected from prolonged exposure to sunlight or chemicals. Periodically check connectors for corrosion or wear and replace the cable if outer jacket damage or persistent signal loss is observed. For critical measurements, verify return loss and insertion loss against system tolerances and consider using calibrated test leads where required.
