## Summary description

Coaxial cable Rangeful HF400-NF-SM-3 is a 3-meter UltraFlex RF cable with an SMA male connector on one end and an N female connector on the other. Designed for reliable signal transmission in antenna, test and measurement, and RF connectivity applications. Flexible construction simplifies routing in tight spaces and supports stable connections between devices.

## Long description

Rangeful HF400-NF-SM-3 is a 3-meter UltraFlex coaxial cable with an SMA male connector on one end and an N female connector on the other. Designed for RF connectivity in antenna systems, test and measurement setups, and general radio-frequency signal routing, this cable combines flexibility with consistent electrical performance. The UltraFlex construction allows easier installation in confined spaces while maintaining mechanical durability and signal integrity across typical RF frequency ranges.
Advantages
The cable’s flexible jacket and braided shielding reduce strain on connectors and simplify routing through equipment racks and tight conduits. SMA male to N female termination provides compatibility between small-form-factor devices and larger RF equipment without adapters. Solid dielectric geometry and quality connector assembly ensure consistent impedance and low insertion loss for reliable signal transmission in measurement and antenna applications.
Suitable for
Connecting antennas to receivers or transmitters where SMA-to-N interface is required
Laboratory test and measurement connections between RF instruments
Temporary or permanent installations in rack-mounted or bench setups with limited cable space
Signal routing in wireless infrastructure and prototyping environments
Key specifications
Cable length: 3 m
Connector A: SMA male
Connector B: N female
Cable type: UltraFlex coaxial
Typical impedance: 50 Ω
Construction: braided shield with flexible outer jacket
Primary use: RF signal transmission for antenna and test equipment
How to use
Inspect both connector interfaces and mating ports to ensure they are clean and free of debris before connecting. Align the SMA male threads with the mating SMA jack and engage by hand, tightening gently to avoid over-torquing; use a torque wrench if precise torque values are required by your equipment. Connect the N female end to the corresponding N male port, ensuring a firm seated connection. Route the cable with gradual bends to preserve the UltraFlex structure and avoid sharp kinks; secure with Velcro straps or cable ties placed loosely to prevent compression damage to the jacket or braided shield.
Usage recommendations
Maintain bend radii greater than the manufacturer’s recommended minimum to minimize insertion loss and mechanical stress. Avoid repeated flexing at connector joints, and store the cable coiled without tight loops. For critical measurement tasks, verify connections with a VNA or appropriate test equipment to confirm expected return loss and insertion loss values before taking measurements.
