External antennas can make a world of difference in wireless applications! This basic 2.4 – 2.5 GHz antenna is approximately 4” / 100mm long and provides an additional 2.5dBi of gain. The Antenna itself has a swivel base and a standard SMA connector. We also include an SMA-uFL adapter cable – this cable is panel mountable – so you can externally mount this antenna while keeping your small IoT board or other wireless device safely tucked away inside a box.
