Coaxial Cable ALLNET ANT-PIG-UFL-SMAF-30 0.3m U.FL SMA Black Gold

The ALLNET ANT-PIG-UFL-SMAF-30 is a 0.3m coaxial cable with a U.FL (micro) connector on one end and a female SMA connector on the other. Designed for reliable RF signal transmission, this cable connects miniature wireless modules to external antennas or test equipment. Its compact length and robust connectors make it suitable for embedded systems, development boards and lab use where a short, high-quality coaxial jumper is needed.

Advantages

This coaxial cable offers stable RF performance with low signal loss over a short distance, thanks to its precision connectors and controlled impedance. The U.FL end provides a space-saving connection to small RF modules, while the SMA female end ensures secure mating with standard antennas and equipment. The black outer jacket combined with gold-plated contacts improves corrosion resistance and maintains good conductivity.

Suitable for

• Connecting Wi‑Fi, Bluetooth or cellular radio modules to external antennas
• Prototyping and development with single-board computers and RF evaluation boards
• Laboratory testing and measurement setups requiring short jumper cables
• Replacement or extension of internal antenna leads in compact devices

Key specifications

• Cable length: 0.3 m
• Connector A: U.FL (micro coaxial)
• Connector B: SMA female
• Impedance: 50 Ω (nominal)
• Outer jacket colour: black
• Contact plating: gold-plated contacts for improved conductivity

How to use

Align the U.FL connector carefully with the module’s U.FL socket and press gently until it snaps into place; avoid applying lateral force that could damage the tiny connector. Screw the SMA female connector onto the mating SMA male thread on the antenna or instrument, ensuring a snug but not over-tightened connection. Route the cable to avoid sharp bends and stress points; the short 0.3 m length is intended for close-proximity connections and internal cabling.

Usage recommendations

Use this cable where minimal length is required to reduce signal loss. Handle the U.FL connection with care and avoid frequent mate/unmate cycles; if repeated connecting is necessary, consider using an adapter or a more robust connector. For outdoor or high-vibration environments, verify mechanical securing of connectors and consider additional strain relief.
