SPE-16-8-24/B/WY 

## **1. Introduction** 

The WCM.01 2.4GHz antenna is the smallest RP-SMA(M) external antenna in the market, fitting into spaces no other traditional monopole, dipole or rubber ducky antenna can go. A unique PIFA design ensures omnidirectional gain across 2.4GHz to 2.5GHz ensuring constant reception and transmission to make it a great Wi-Fi antenna for 2.4GHz Wi-Fi and Bluetooth applications. 

This antenna features greater than 60% efficiency when connected directly to the ground plane of the device. 

Typical Applications 

- Application Points 

- Routers 

- IoT M2M devices 

- Smart home applications 

This antenna comes with a RP SMA(M) to be compatible with most Wi-Fi applications and routers in the market. The WCM.01 antenna is also IP67 water resistant. The ideal position for the antenna to radiate is mounted clear of metal. Connector is customizable.
