Coaxial cable Rangeful HF240 N plug to SMA plug, 15 m, HF240 series, pure copper

Rangeful HF240 coaxial cable with N plug to SMA plug connectors, 15 m long, features an HF240 series construction and a pure copper conductor to ensure stable RF signal transmission between devices with N and SMA ports. The cable is intended for mid-range connections where flexibility and reliable shielding are required, suitable for laboratory setups, field tests and fixed installations that demand consistent impedance and low insertion loss for common RF applications.

Advantages

The HF240 construction delivers a balance of flexibility and mechanical strength while maintaining impedance stability. A pure copper inner conductor provides good conductivity and signal integrity across the intended frequency range. Precision N and SMA plugs ensure secure, threaded connections and minimize reflections at connector interfaces. The 15 m length allows for flexible routing without the need for intermediate amplification in many setups.

Suitable for

• Connecting antennas to transceivers or external amplifiers
• RF test and measurement setups in laboratories and field environments
• Integration between equipment with N and SMA ports in radio systems
• Temporary or permanent installations requiring a mid-range coaxial link

Key specifications

• Connector types: N plug (male-threaded) to SMA plug (male-threaded)
• Cable length: 15 m
• Conductor material: pure copper inner conductor
• Cable series: HF240 series construction
• Characteristic impedance: 50 ohm (standard for N–SMA interconnects)
• Flexible jacket suitable for routing in indoor and light outdoor use

How to use

Connect the N plug to the corresponding N jack on the device or antenna, ensuring the threads engage smoothly and are hand-tightened to avoid cross-threading; then attach the SMA plug to the SMA jack and tighten by hand or with a torque wrench to the manufacturer’s recommended torque if specified. Route the cable to avoid sharp bends, kinks or compression that could damage the shielding or change impedance. When installing outdoors or in exposed environments, protect connector interfaces from moisture and contaminants using appropriate sealing methods or weatherproof boots.

Usage recommendations

For optimal RF performance, avoid repeated flexing near the connector ends, verify connectors are clean before mating, and maintain bend radius greater than the cable manufacturer’s minimum to preserve signal integrity. Where possible, use proper torque values for SMA and N connectors and employ adapters only when necessary to prevent additional insertion loss.
