863-873 MHz Mini Rubber Duck Antenna with SMA Male Straight Connector

Eteily Technologies' 863-873 MHz Mini Rubber Duck Antenna is a tiny, omnidirectional external antenna for IoT, LoRa, and LPWAN applications in the 863 - 873 MHz sub-GHz range. This antenna, designed for low-power wide-area network devices, provides balanced performance in a tiny form factor and has a straight SMA male connection for simple integration with gateways, nodes, sensors, and other wireless devices. The robust ABS construction and continuous 50 Ω impedance ensure reliable signal radiation with a low VSWR, making it ideal for dense IoT installations and rural networks.

Key Features:

1. Frequency Range

• Designed for the 863 - 873 MHz band, it is suited for LoRa/LPWAN, ISM, and other sub-GHz IoT applications in Europe and Asia.

2. Radiation Pattern

• The omnidirectional pattern provides equal signal reception and transmission in all horizontal directions, which is ideal for devices without a set orientation.

3. Connector Type

• The straight SMA male connection ensures plug-and-play compatibility with the majority of RF modules, gateways and wireless interfaces.

4. Compact Dimensions

• The device's dimensions are around 21 mm in length and 9 mm in diameter, making it ideal for IoT nodes or embedded systems with limited space.

5. Standard Impedance

• When combined with compatible RF equipment, the impedance of 50 Ω enables efficient power transmission and reduced reflection.

6. VSWR Performance

• VSWR ≤ 2 indicates balanced antenna matching over the operational band and consistent performance.

Typical Applications:

• LoRaWAN IoT nodes and gateways
• LPWAN sensor devices (e.g., environmental and smart metering)
• Sub-GHz telemetry and telematics systems - Industrial IoT communication links
• Smart agriculture and asset tracking installations.
