Coaxial cable Rangeful HF400-NF-SM-1 1 m, SMA male to N female, UltraFlex HF400

Rangeful HF400-NF-SM-1 is a 1 m coaxial jumper cable with an SMA male connector on one end and an N female connector on the other. Built on UltraFlex HF400 construction, the cable provides increased flexibility for tight routing while maintaining consistent RF performance across common cellular, Wi‑Fi and test frequencies. This flexible jumper is intended for short interconnections between antennas, test instruments and small RF systems where a compact, reliable RF link with standard SMA and N interfaces is required.

Advantages

The UltraFlex HF400 construction results in reduced bending radius and easier handling compared with standard RG‑type assemblies, allowing installation in confined spaces without compromising signal integrity. SMA male and N female connectors offer common, mechanically robust interfaces for many antennas and laboratory instruments. The 1 m length balances reach and minimal insertion loss for short runs, and the cable assembly is designed for repeatable connections and stable impedance to preserve RF performance.

Suitable for

• Connecting antennas to routers, modems or radio units where SMA and N interfaces are used
• Short jumper between RF test equipment and devices under test in labs
• Small-scale RF installations and prototyping with limited routing space

Key specifications

• Cable type: UltraFlex HF400 coaxial construction
• Length: 1 meter
• Connector A: SMA male
• Connector B: N female
• Characteristic impedance: 50 Ω
• Suitable frequency range: typical cellular, Wi‑Fi and general RF test bands (consult system requirements for exact limits)
• Flexibility: reduced bending radius for tight routing

How to use

Verify that the system components use 50 Ω impedance and compatible SMA male / N female interfaces before installation. Align the SMA male pin carefully with the mating SMA female socket and screw the SMA connector finger‑tight; avoid over‑torquing to prevent connector damage. Secure the N female by hand and, if needed, use the appropriate torque wrench to the manufacturer's recommended torque. Route the cable following natural bends and avoid sharp kinks; maintain gentle curves to preserve cable performance. For test setups, connect the cable between instrument RF ports and the device under test, ensuring stable mechanical support to prevent connector strain during measurements.

Usage recommendations

Inspect connectors periodically for dirt or damage and clean with suitable, non‑conductive tools if necessary. Avoid repeated excessive flexing near the connector ends; when frequent reconnection is anticipated, inspect threads and mating surfaces for wear. For outdoor or harsh environments, use appropriate environmental protection or weatherproofing accessories since this assembly is intended for indoor and controlled environments unless specified otherwise.
