865MHz Helium Frequency 9dBi Rubber Duck Antenna with SMA Male Movable Connector

The 865 MHz Helium Frequency 9dBi Rubber Duck Antenna with SMA Male Movable Connector is a specialized antenna designed for specific wireless communication applications. Here's a detailed breakdown of its features and uses:

1. Frequency:

   • 865 MHz: This frequency is commonly used for UHF RFID systems and is part of the ISM (Industrial, Scientific, and Medical) band. In the context of Helium Network (LoRaWAN), 865 MHz is used in some regions for IoT (Internet of Things) applications, including low-power wide-area networks (LPWAN).

2. Gain:

   • 9dBi: The gain of 9dBi indicates that the antenna is relatively high-gain, meaning it can focus the radio frequency energy more effectively in a particular direction compared to a standard isotropic radiator. This enhances signal strength and range.

3. Rubber Duck Design:

   • Rubber Duck: This is a term for a compact, flexible antenna with a relatively short design. It’s known for its durability and ease of use. While it’s not as high-gain as other types of antennas, it provides a good balance between performance and convenience.

4. Connector:

   • SMA Male Movable Connector: The SMA (SubMiniature version A) connector is a popular choice for many RF applications. The “movable” aspect indicates that the connector might be adjustable or able to swivel, which can be useful for fine-tuning the antenna's orientation to achieve the best signal reception.

1. Helium Network (LoRaWAN):

   • IoT Applications: This antenna is well-suited for use with LoRaWAN gateways or end devices operating in the 865 MHz band. It enhances the connectivity and range of devices in a Helium Network setup, which is used for various IoT applications like smart agriculture, asset tracking, and environmental monitoring.

2. UHF RFID:

   • Asset Tracking: While not specifically optimized for RFID, the antenna can be used in systems operating in the UHF band for reading RFID tags over moderate distances.

3. Wireless Communication:

   • General Use: The antenna can be used in other wireless communication systems operating in the 865 MHz range where a balance of gain and compact design is needed.

1. Mounting:

   • The rubber duck design is flexible and can be mounted in various positions, though it’s typically used in situations where a compact, versatile antenna is beneficial.

2. Connector Orientation:

   • The movable SMA connector allows for flexible installation and alignment, which helps in achieving optimal signal reception and minimizing signal loss.

3. Environment:

   • While the rubber duck antenna is durable, consider the installation environment. If used outdoors or in harsh conditions, ensure that it is protected from extreme weather or physical damage.

Overall, this antenna is a practical choice for applications requiring moderate gain and flexibility in a compact form factor, particularly in the context of Helium Network deployments and other 865 MHz wireless systems.
