Coaxial cable Rangeful HF240 SMA Plug to SMA Socket, double coaxial, 7 m, pure copper

Rangeful HF240 double coaxial cable with SMA plug to SMA socket is a 7-meter RF connection cable constructed with pure copper conductors. The cable assembly provides a standard SMA interface on both ends — a male (plug) and a female (socket) connector — and uses a double coaxial design to support stable signal transmission for antenna, router and measurement applications over the specified length.

Advantages

The double coaxial construction reduces interference between conductors and helps maintain characteristic impedance along the cable run. Pure copper conductors offer low resistance and predictable attenuation characteristics for RF signals. A 7 m length enables flexible placement of devices and antennas while retaining consistent SMA connectivity for test equipment or network hardware.

Suitable for

• Connecting antennas to routers, modems or radio transceivers
• Laboratory and field RF test setups and measurement chains
• Amateur radio and short-range transmission experiments
• Extending SMA-equipped devices where low-loss, flexible cabling is needed

Key specifications

• Cable type: double coaxial construction
• Connector A: SMA plug (male)
• Connector B: SMA socket (female)
• Length: 7 meters
• Conductor material: pure copper
• Intended use: RF/antenna connections and measurement setups

How to use

Align the SMA plug with the SMA socket and tighten the connector by hand until secure; use a torque wrench set to the recommended torque for SMA connectors if precise mechanical specification is required. Route the cable avoiding sharp bends and excessive compression; maintain a bend radius consistent with the cable’s mechanical flexibility to minimise signal degradation. Inspect connectors for debris or damage before connection and ensure mating surfaces are clean for reliable contact.

Usage recommendations

For best performance, avoid running the cable parallel and in close proximity to strong power lines or noisy digital signal sources. If the cable is used in measurement or calibrated systems, account for insertion loss over 7 m in link budget calculations. Store the cable coiled loosely and protect connector ends with caps when not in use.
