868mhz 2.5dbi Rubber Duck Antenna With Sma (m) R/a Connector

The 868 MHz 2.5dBi rubber duck antenna is a type of antenna commonly used in wireless communication systems, particularly in the ISM (Industrial, Scientific, and Medical) band, which is used for various wireless applications like IoT devices and telemetry.

Here’s a quick rundown of its features and uses:

• Frequency Range: The antenna is designed for the 868 MHz frequency, which is often used in Europe for LPWAN (Low Power Wide Area Network) technologies like LoRaWAN.
• Gain: The 2.5 dBi gain refers to the antenna's ability to direct or concentrate the radio signal in a particular direction. A 2.5 dBi gain provides a moderate increase in signal strength compared to an isotropic radiator, which can improve communication range and signal quality.
• Design: The term "rubber duck" refers to the antenna's shape and construction. These antennas are usually compact, flexible, and rugged, making them suitable for portable or industrial applications where durability and ease of use are important.
• Application: This antenna is often used in devices such as remote sensors, monitoring systems, and other wireless equipment operating in the 868 MHz band.

If you're selecting an antenna for a specific application, make sure it matches the frequency requirements and provides the coverage you need.
