Jetson Nano Antennas at a reasonable price. If you buy from Arrow, they charge a $13 shipping fee which I found exhorbitant. I am basically passing these antennas through at cost+shipping.
Molex’s new 2042811100 Wi-Fi antenna is RoHS compliant, and compatible with BLE, Bluetooth, and Zigbee wireless standards. The 2042811100 is designed for the Internet of Things and features a tiny .10mm x 11.00mm x 35.00mm (DxWxL) footprint, making it easy to install in even the smallest of IoT devices.
