Coaxial cable Rangeful HF240 50 Ω, N male to SMA male, 3 m

Rangeful HF240 50 Ω coaxial cable with N male to SMA male connectors, 3 m long, provides impedance-matched RF signal transmission for antenna, radio and test applications. The cable is intended to connect devices with N and SMA ports while maintaining a stable 50-ohm characteristic impedance over the cable length. Its construction balances flexibility and shielding to reduce signal loss and preserve connection integrity in installations where a reliable RF link is required.

Advantages

The cable offers a standardized 50 Ω impedance suitable for most RF systems, ensuring minimal reflections and consistent power transfer between equipment with N and SMA connectors. With factory-installed N male and SMA male terminations it eliminates the need for on-site crimping or assembly. The 3 m length provides flexibility for typical rack, bench and field setups while preserving manageable signal attenuation. The design emphasizes mechanical durability at connector junctions and effective shielding to reduce external interference.

Suitable for

• Connecting antennas to routers, base stations and RF radios with N or SMA ports
• Linking measurement instruments and signal generators to devices under test
• Laboratory and field test setups where a fixed 50 Ω coaxial connection is required
• Temporary or permanent installations in communications and wireless testing

Key specifications

• Characteristic impedance: 50 Ω
• Connector A: N male
• Connector B: SMA male
• Length: 3 m
• Cable type: RF coaxial cable designed for 50 Ω systems
• Typical use: antenna, radio and test equipment interconnection

How to use

Inspect both mating connectors for cleanliness and any visible damage before connecting. Align the N male and SMA male connectors with their respective female ports and engage by hand; avoid cross-threading and tighten to the recommended hand or wrench torque appropriate for N and SMA connectors. Route the cable to avoid sharp bends and excessive tension; maintain the cable bend radius recommended for RF coaxial cables of similar construction. When disconnecting, first loosen the connector coupling and then withdraw the connector straight to avoid damage to the center pin or dielectric.

Usage recommendations

For best RF performance, keep the cable length as short as practical for your setup, protect connector interfaces from moisture and contaminants with caps when not in use, and avoid repeated excessive bending near the connector ends. For precise measurements, verify system calibration with the cable in place or use a reference cable with known characteristics.
