Coaxial cable Rangeful HF240 SMA male to SMA male twin, 15 m, 50 Ω

Rangeful HF240 SMA male to SMA male twin coaxial cable, 15 m length and 50 Ω impedance, is designed for RF signal transmission between devices with SMA ports. The twin construction provides two identical coax lines in a single jacket, maintaining matched impedance to minimise signal reflections and ensure consistent performance across the length of the cable. This cable is suitable for connections where a reliable 15 m SMA-to-SMA lead is required.

Advantages

The Rangeful HF240 twin cable features low-loss HF240 dielectric and a shielding design that reduces external interference and crosstalk between the two conductors. SMA male connectors on both ends ensure secure, threaded connections with standard SMA ports. The 50 Ω impedance matches common RF equipment, reducing VSWR and preserving signal integrity for transmitting and receiving radio-frequency signals over moderate distances.

Suitable for

• Amateur radio transceiver to antenna or duplexer connections
• RF test setups and laboratory measurements
• Antenna feedlines for short to medium runs where SMA connectors are used
• Signal distribution between equipment racks or test instruments

Key specifications

• Cable type: twin coaxial with two parallel 50 Ω conductors
• Length: 15 m
• Characteristic impedance: 50 Ω
• Connectors: SMA male to SMA male (threaded)
• Dielectric/insulation: HF240-grade (low-loss) construction
• Shielding: braided/coaxial shielding to reduce EMI and crosstalk
• Operating frequency: suitable for common RF frequency ranges where SMA is used (VHF/UHF and many microwave applications depending on system requirements)

How to use

Connect each SMA male connector to the corresponding SMA female port on your devices by aligning threads and hand-tightening; avoid using excessive torque or pliers to prevent damage to connector threads. Route the 15 m twin cable to minimise sharp bends and avoid running parallel to high-power AC cables to reduce interference. Ensure connectors and ports are clean before mating; inspect the central pin alignment visually where accessible. For test setups, verify continuity and insertion loss with appropriate RF test equipment after installation.

Usage recommendations

Use this twin SMA cable in environments free of excessive mechanical strain, securing the cable with non-compressive clips or Velcro straps. For long-term outdoor exposure or installations near corrosive elements, consider additional protective jacketing or conduit. When precise measurements are required, perform calibration with the cable in place to account for its insertion loss and phase characteristics.
