Coaxial cable Rangeful HF240T-SM-SF-12 — SMA plug to SMA socket, HF240 double coaxial, 12 m, pure copper

The Rangeful HF240T-SM-SF-12 is a 12 m HF240 double coaxial cable with an SMA plug to SMA socket termination and pure copper conductors. It is made for RF and high-frequency signal transmission where a long, flexible lead is needed between SMA-equipped devices. The cable construction uses two coaxial cores to reduce interference and maintain signal integrity over the 12 m length, making it suitable for laboratory test setups, antennas, radio equipment, and general RF cabling tasks that require durable pure-copper conductors and reliable SMA terminations.

Advantages

The double coaxial HF240 structure provides improved shielding and reduced crosstalk compared with single-core coaxial leads of similar diameter. Pure copper conductors ensure low DC resistance and consistent RF performance across the operating frequency range. SMA plug to SMA socket terminations offer a compact, screw-on connection that is widely compatible with test instruments, antennas and radio modules. The 12 m length gives extended reach for flexible routing while preserving mechanical flexibility for easier handling in crowded setups.

Suitable for

• Bench and laboratory RF measurements and test setups
• Connecting antennas to radio transceivers or receivers
• Linking SMA-equipped modules, filters and amplifiers
• Temporary or permanent RF cabling where a long flexible lead is required

Key specifications

• Cable type: HF240 double coaxial
• Length: 12 m
• Conductors: pure copper
• Termination: SMA plug to SMA socket (screw-on)
• Construction: dual coaxial cores with shielding for reduced interference
• Flexibility: designed for routing and repeated handling in test environments

How to use

Connect the SMA plug end to the SMA socket of the source device and tighten the connector gently by hand until secure; then attach the SMA socket end to the destination device and secure it similarly. Ensure connectors are clean and free from debris before mating to avoid damage to the center pin and dielectric. Route the cable to avoid tight bends, sharp kinks or excessive torsion; maintain a bend radius consistent with the cable diameter to preserve electrical characteristics. For safety, power down equipment when making or breaking RF connections whenever practical.

Usage recommendations

For best RF performance, keep connector interfaces dust-free and inspect the pure copper conductors and shields periodically for corrosion if used in humid environments. Avoid coiling the cable tightly when storing; use loose loops to prevent strain. If used in precision measurement work, minimize cable movement during measurements and verify system calibration after long cable runs.
