DELTA12B/X/SMAM/S/S/17

Overview

The Siretta DELTA12B/X/SMAM/S/S/17 is an omnidirectional ISM band antenna designed for flexible installation. It operates at a center frequency of 869 MHz with a gain of 3 dBi. The antenna features a 130mm flexible rubber whip element and utilizes an SMA male connector. It supports direct mounting configurations, providing reliable RF performance for industrial applications requiring robust connectivity in the sub-GHz spectrum.

Feature Summary

• Flexible rubber whip construction for adaptable positioning
• Omnidirectional radiation pattern for consistent coverage
• Integrated SMA male connector for standard interface compatibility

Applications

• Industrial Wireless Sensor Networks (IWSN)
• Remote monitoring systems
• Automated meter reading infrastructure

Procurement Notes

Verify that the specific SMA male connector polarity matches the receiving equipment interface requirements. Confirm that the operating environment temperature range aligns with the component specifications to ensure long-term reliability. Ensure the mounting location does not obstruct the omnidirectional signal propagation path.

Selection Notes

Select this model when a compact, flexible solution is required for sub-GHz ISM bands. The 3 dBi gain offers a balance between size and performance. Consider the 130mm length for spatial constraints where larger antennas are unsuitable but higher gain than PCB options is needed.

Part Context

This component belongs to the Siretta DELTA series, which focuses on versatile ISM band solutions. The DELTA12B variant specifically targets the 869 MHz frequency region, distinguishing it from other models in the family that may operate at different frequencies such as 915 MHz or 433 MHz.

Replacement Considerations

The DELTA12C/X/SMAM/S/S/17 serves as a functional substitute for similar 915 MHz applications, though frequency differences must be evaluated. No direct identical frequency replacement is confirmed in public documentation.
