## Summary description

Coaxial cable Rangeful HF400 with SMA male to N male connectors, 3 m length, HF400 construction and 50 Ω impedance. Made with full-copper conductors and flexible jacket for reliable RF signal transmission. Suitable for connecting antennas, radio equipment, test instruments and other RF devices where stable 50 Ω performance and durable copper conductors are required.

## Long description

Rangeful HF400 coaxial cable with SMA male to N male connectors, 3 m length, HF400 construction and 50 Ω characteristic impedance, designed to provide stable RF signal transmission. The cable features full-copper conductors and a flexible outer jacket that facilitates routing and connection between antennas, radio equipment, test instruments and other RF devices requiring 50 Ω matching and robust conductivity.
Advantages
The HF400 cable offers low-loss performance typical for HF400-type coax, a consistent 50 Ω impedance for minimal signal reflections, and full-copper inner conductor and braid for improved conductivity and corrosion resistance compared to tinned alternatives. The SMA male and N male connectors provide reliable mechanical mating and wide compatibility with many RF transceivers and antenna systems. A flexible jacket and three-meter length simplify installation in confined or mobile setups.
Suitable for
Connecting antennas to radio transceivers and repeaters
Linking test instruments and RF measurement equipment
Mobile and fixed radio installations requiring 50 Ω matching
Laboratory setups and prototyping of RF circuits
Key specifications
Cable type: HF400 construction
Connector A: SMA male
Connector B: N male
Length: 3 m
Characteristic impedance: 50 Ω
Conductor material: full copper (inner conductor and braid)
Jacket: flexible outer jacket suitable for routing
How to use
Inspect connectors and cable for visible damage before installation. Align the SMA male and N male connectors with the mating ports and engage by hand, ensuring threads are started correctly to avoid cross-threading. Tighten connector interfaces to the appropriate torque recommended for SMA and N connectors to ensure reliable electrical contact; when torque tools are not available, tighten hand-tight and then apply a small additional rotation with a wrench. Route the cable to avoid sharp bends and kinks; maintain a bend radius consistent with HF400 flexible cable specifications to prevent increased loss or mechanical damage.
Usage recommendations
For best RF performance, minimize unnecessary cable length runs, avoid tight bends and crushing, and protect connectors from moisture and mechanical strain. Use appropriate torque settings for SMA and N connectors and verify continuity and VSWR with measurement equipment after installation when precision matching is required.
