Wi‑Fi / Bluetooth λ/2 Whip Antenna

Standard

This Wi‑Fi / Bluetooth Low Energy (BLE) external whip antenna operates at 2.4 GHz and delivers an omnidirectional radiation pattern. Rated IP67 for dust and water protection, it ensures stable wireless connectivity in harsh environments.

The λ/2 design eliminates the need for a ground plane. It maintains stable radiation efficiency and impedance matching without dependence on ground plane size. The housing uses weather‑resistant ASA material with UL94 V‑0 flame rating, making it suitable for long‑term outdoor deployment. IP67 sealing protects against dust ingress and water immersion.

Each unit undergoes 100% waterproof inspection prior to shipment. Secure installation is achieved using a torque wrench to ensure proper fastening. Ideal for high‑reliability remote monitoring systems, agriculture cloud devices, smart meters, industrial sensing equipment, and food temperature traceability terminals.
