2.4GHz Antenna - Adhesive (U.FL Connector)

A compact, adhesive-backed omni-directional antenna with a U.FL connector, ideal for getting a wireless signal out of enclosed projects. Despite the 2.4 GHz name, this antenna is actually dual-band, covering 2300–3800 MHz and 5150–5875 MHz — so it works for WiFi (2.4 GHz and 5 GHz), Bluetooth, and ZigBee.

Peel off the adhesive backing, stick the antenna to the inside of your enclosure, and connect via the 350 mm U.FL cable.
