U.FL / I-PEX to SMA Male Antenna Cable 120mm for LoRa Boards

Add an external SMA antenna to your LoRa board. This U.FL (I-PEX) to SMA Male cable connects the tiny U.FL antenna socket on boards like the Heltec series, WisBlock modules, and Grove LoRa modules to a standard SMA antenna. It is one of the most common and useful cables in any Meshtastic or MeshCore build, and one of our best-rated accessories.

Snap the U.FL end onto your board, and the SMA Male end is ready for any SMA-Female antenna, giving you a proper external antenna instead of relying on a tiny onboard one.

What It Connects

• U.FL (I-PEX / IPEX1 / MHF1) on one end: snaps onto the small antenna socket found on most LoRa development boards
• SMA Male on the other end: accepts any SMA-Female antenna, or mounts through an enclosure with an SMA bulkhead adapter

Key Features

• 1.13mm coax: thin and flexible, ideal for routing inside tight enclosures
• 120mm length: the right length for board-to-antenna or board-to-enclosure runs without excess slack
• U.FL / I-PEX standard connector: fits the vast majority of LoRa, ESP32, and nRF52 boards
• 50Ω impedance: matched to all standard LoRa radios and antennas
• Highly rated: a proven, reliable cable rated 98% by users on the manufacturer's own store

Compatible Boards

• Heltec WiFi LoRa 32 V3 and V4 (U.FL socket)
• Heltec Wireless Tracker V2
• RAKwireless WisBlock modules with U.FL antenna socket
• Seeed Grove LoRa modules (Wio-E5 and similar)
• Most ESP32 and nRF52 LoRa boards with a U.FL / I-PEX socket

Important: This Is Standard U.FL, Not MHF4

This cable uses the standard U.FL (also called I-PEX, IPEX1, or MHF1) connector, which is the most common size. Some newer, very compact boards use the smaller MHF4 connector instead, which is not compatible with this cable. If your board has the smaller MHF4 socket, use our MHF4 pigtail instead. When in doubt, check your board's datasheet.
