Coaxial cable Rangeful HF240T-NMH-SM-3 — SMA male to N male, double HF240 hex coax, 3 m, pure copper

The Rangeful HF240T-NMH-SM-3 is a 3 m coaxial cable assembly that terminates with an SMA male connector on one end and an N male connector on the other. Built with dual HF240 hex coax conductors and pure copper materials, this cable is designed to provide consistent RF signal transmission with reduced insertion loss and enhanced mechanical durability. Its construction supports laboratory testing, antenna connections and field measurements where stable, low-loss RF connections are required.

Advantages

This coaxial cable offers low signal attenuation through its HF240 double-hex design and pure copper conductors, ensuring reliable RF performance across a broad frequency range. The SMA male and N male connectors are robust and widely compatible with test instruments and RF equipment. The 3 meter length provides flexibility in bench setups and installations while maintaining mechanical strength for repeated use.

Suitable for

• Laboratory RF testing and measurements
• Antenna connections for radio equipment
• Field diagnostics and portable test setups
• Signal routing between instruments with SMA and N interfaces

Key specifications

• Cable length: 3 meters
• Cable conductor material: pure copper
• Cable construction: double HF240 hex coax
• Connector A: SMA male
• Connector B: N male
• Design purpose: low-loss RF signal transmission and mechanical durability

How to use

Inspect connectors and cable for visible damage before use. Connect the SMA male end to the device or adapter with an SMA female port and tighten by hand or with the recommended torque specification for SMA connectors if available. Attach the N male end to the corresponding N female port and secure using the coupling nut until hand-tightened and then with a torque wrench if a precise torque is required. Route the cable to avoid sharp bends, crushing, or tension that could compromise the double-hex geometry or connector integrity. For repeated connects and disconnects, keep threads clean and aligned to prevent cross-threading.

Usage recommendations

For optimal long-term performance, avoid exposing the cable to excessive torsion, prolonged UV exposure, or corrosive environments. Use proper connector torque and store the cable coiled loosely without tight loops. When used in precision measurement setups, verify system calibration after installing the cable to account for insertion loss and return loss characteristics.
