The UFL-SMAF Pigtail is a specialised RF interconnect cable designed to bridge the gap between internal U.FL (IPEX/IPX) connectors on wireless modules and external SMA-based antenna systems. This pigtail is essential for projects requiring the connection of external antennas—such as the MikroTik mANT LTE 5o (ANT-MLTE)—to internal hardware, ensuring a stable, low-loss signal path for LTE and various other RF applications.
Technical Specifications
- Connector A: U.FL (IPEX/IPX) Female
- Connector B: SMA Female (Bulkhead Mount)
- Impedance: 50 Ohms
- Compatibility: Designed for LTE, 4G, 5G, GPS, and LoRa wireless modules
- Cable Type: High-frequency coaxial (typically 1.13mm or RG178 series)
- Application: Internal-to-External antenna bridging
Key Features
- Seamless Integration: Specifically enables the use of external, high-performance antennas (like the MikroTik ANT-MLTE) with devices that utilise compact, internal board-level U.FL connectors.
- Bulkhead Mounting: The SMA Female end features a bulkhead mount, allowing you to securely fasten the connector to an enclosure or chassis for a professional, dust-resistant finish.
- RF Optimised: Engineered for low signal attenuation across the common LTE frequency spectrum (699–2690 MHz), ensuring you retain the performance gains provided by your external antenna.
- Versatile Utility: While ideal for LTE applications, the 50-ohm impedance ensures it remains compatible with a wide range of wireless protocols, including Wi-Fi and IoT-based communications.
Implementation Note
When connecting the U.FL end to your wireless card or router board, please handle the connector with care. U.FL connectors are miniature components and are designed for a limited number of mating cycles; ensure the connection is seated firmly until you hear a “click” to guarantee proper signal integrity.
