Network Cable MikroTik OEM Pigtail U.fl Female / SMA Female 20cm Black

The MikroTik OEM Pigtail U.fl Female / SMA Female 20cm in black is a short RF jumper cable designed to connect devices with U.FL (U.fl) antenna connectors to external antennas or adapters with SMA female interfaces. With a compact 20 cm length and flexible construction, the cable preserves radio-frequency signal integrity while allowing tidy routing inside enclosures or between nearby components in wireless routers, access points and cellular modules.

Advantages

This pigtail cable combines a low-profile U.fl female connector with a standard SMA female connector to offer compatibility with a wide range of wireless equipment and antennas. The 20 cm length reduces insertion loss compared with longer leads and simplifies internal connections without excess slack. The black outer jacket provides basic protection against abrasion and helps conceal the cable inside devices or racks. The cable is manufactured to maintain consistent impedance and minimize reflections for stable RF performance.

Suitable for

• Connecting internal wireless modules or mini PCIe cards to external antennas
• Extending or adapting U.FL antenna ports to SMA-equipped antennas and adapters
• Routing RF connections within wireless routers, access points and IoT gateways
• Temporary or prototype setups where a short, flexible RF jumper is required

Key specifications

• Connector A: U.FL (U.fl) female
• Connector B: SMA female
• Length: 20 cm
• Outer color: black
• Application: RF jumper for Wi‑Fi, cellular and other wireless equipment
• Construction: flexible coaxial cable designed for low insertion loss at typical antenna frequencies

How to use

Locate the U.FL connector on the wireless module or device and press the cable’s U.FL female connector straight onto the board-mounted U.FL jack until it clicks into place. Attach the SMA female end to the corresponding SMA male antenna or adapter by engaging the threaded coupling and turning until hand-tight; avoid over-tightening. Route the cable to avoid sharp bends and contact with sharp edges, and secure it with gentle clips or tape if needed to prevent stress on the small U.FL connection.

Usage recommendations

Handle the U.FL connector with care: it is small and intended for limited mating cycles. For permanent installations, consider strain relief at both ends and avoid repeated disconnects. If using at higher frequencies or in demanding outdoor environments, verify connector sealing and cable loss against system requirements and select weatherproof adapters where necessary.
