Coaxial cable Rangeful SMA (male) to N (male) HF240T-NMH-SM-7 7 m pure copper double-coax hex

This Rangeful HF240T-NMH-SM-7 coaxial cable provides a 7 m connection between an SMA male and an N male connector. The cable uses pure copper conductors and a double-coax construction to maintain signal integrity and reduce loss across the length. Hexagonal connector bodies allow reliable wrench tightening for secure mechanical and electrical joints. The cable is intended for RF signal transmission between antennas, test and measurement equipment, and communication devices where a longer, low-loss coax link is required.

Advantages

The double-coax design improves shielding and reduces external interference while pure copper conductors offer consistent conductivity and lower attenuation compared with plated alternatives. Robust SMA male and N male terminations with hex bodies simplify installation and provide stable, repeatable connections. The 7 m length enables flexible placement of antennas or test instruments without sacrificing signal quality.

Suitable for

• Connecting antennas to radios and transceivers over intermediate distances
• Laboratory and test-bench RF setups requiring standard SMA and N interfaces
• Field or rack installations where secure wrench-tightened connectors are needed
• Communication equipment links in base stations, repeaters, and monitoring systems

Key specifications

• Cable length: 7 m
• Inner conductor material: pure copper
• Construction: double-coax (dual coaxial conductors for improved shielding)
• Connector types: SMA male to N male
• Connector body style: hexagonal for wrench tightening
• Application: RF signal transmission for antennas, test equipment, communications

How to use

Align the SMA male and N male connectors with the device ports and hand-tighten initially. Use an appropriate wrench on the hexagonal connector bodies to complete installation, applying moderate torque to ensure a secure mechanical and electrical connection without over-tightening. Route the cable to avoid sharp bends, kinks, or contact with sharp edges and secure it with suitable clamps or ties at intervals to prevent strain on the connectors. For test setups, verify continuity and insertion loss with suitable RF test equipment after installation.

Usage recommendations

To maintain low loss and long service life, avoid repeated connect/disconnect cycles where possible, keep the cable dry and free of corrosive environments, and prevent excessive bending radii near the connectors. When tightening connectors, follow manufacturer torque guidelines for SMA and N connectors to avoid damaging threads or degrading performance.
