915MHz 2.5dBi Rubber Duck Antenna with SMA (M) R/A Connector

A 915MHz 2.5dBi rubber duck antenna with an SMA (M) R/A (right angle) connector is a compact and versatile antenna suitable for various RF applications. Here’s a breakdown of its features and uses:

Key Features:

1. 915MHz Frequency:

   • The antenna is designed to operate at 915 MHz, which is commonly used in RF communication applications such as RFID, some IoT devices, and certain wireless systems.

2. 2.5dBi Gain:

   • Gain: The 2.5 dBi gain indicates a relatively low gain compared to higher gain antennas. This means the antenna provides a more omnidirectional radiation pattern, offering good coverage in all directions but with less focused signal strength.
   • Omnidirectional Pattern: Ideal for situations where you need a broad coverage area rather than focusing the signal in a specific direction.

3. Rubber Duck Design:

   • Material: Made from flexible and durable rubber or elastomer material, this design is resilient and can withstand some degree of physical stress.
   • Flexibility: The rubber duck design is often used in portable or mobile applications where flexibility and durability are important.

4. SMA (M) R/A Connector:

   • Connector Type: SMA (SubMiniature version A) is a commonly used RF connector type. The (M) denotes that it is a male connector, which has a center pin.
   • Right Angle (R/A): The right-angle configuration allows the antenna to be mounted in a way that doesn't require a lot of vertical space, making it suitable for tight or constrained spaces. It helps to reduce strain on the connector and cable.

Applications:

• Portable Devices: Ideal for portable or handheld devices where a durable, flexible antenna is needed.

• IoT Devices: Common in Internet of Things devices that operate in the 915 MHz band and require a compact, reliable antenna.

• RFID Systems: Used in RFID applications where space is limited, and a low-profile, flexible antenna is advantageous.

• Wireless Communication: Suitable for general wireless communication systems where omnidirectional coverage is needed.

Installation Considerations:

• Mounting: The right-angle SMA connector allows for flexible mounting options. Ensure the antenna is positioned in a way that provides optimal signal coverage for your application.

• Space Constraints: The compact size and flexible nature make it a good choice for devices with limited space or where the antenna needs to be oriented at a particular angle.

• Cable Management: If using with a coaxial cable, ensure that the cable and connector are compatible and securely connected to prevent signal loss or interference.
