The 868 MHz 2.5dBi rubber duck antenna is designed for wireless communication applications operating in the 868 MHz frequency range, which is commonly used for technologies such as LoRaWAN, remote sensing, and telemetry. Here are some key details and benefits of this type of antenna:

Key Features

Frequency Range: Operates at 868 MHz, which is within the ISM (Industrial, Scientific, and Medical) band used in Europe for various low-power, long-range communication applications.
Gain: 2.5 dBi (decibels over an isotropic radiator) gain indicates the antenna's efficiency in focusing energy in a specific direction compared to an ideal isotropic antenna. A gain of 2.5 dBi provides a modest increase in signal strength and range.
Design:
- Rubber Duck Shape: This design is named for its resemblance to a rubber duck toy. It is a flexible, compact, and durable antenna shape.
- Construction: Typically made with a flexible rubber or similar material, which makes it suitable for environments where durability and impact resistance are important.

Advantages

Durability: The rubber or plastic construction helps protect the antenna from physical damage and environmental conditions, making it suitable for rugged or portable devices.
Compact Size: The rubber duck design is generally small and lightweight, making it ideal for use in space-constrained applications.
Ease of Use: The flexible design allows it to be easily mounted or adjusted, making installation straightforward.

Typical Applications

IoT Devices: Used in various Internet of Things (IoT) devices that need to communicate over long distances with low power consumption.
Remote Sensing: Suitable for sensors and monitoring equipment deployed in fields or remote locations.
Telemetry Systems: Often used in systems that transmit data over distances, such as in agricultural or environmental monitoring.

When choosing an antenna, ensure that its specifications match your device's requirements and the operating conditions of your application.
