ALPHA1A/2.5M/SMAM/S/S/11

Overview

The Siretta ALPHA1A/2.5M/SMAM/S/S/11 is a passive RF antenna designed for operation within the 868 MHz and 900 MHz frequency bands. It features an SMA male connector with a 2.5-meter cable length. The unit utilizes a flat bar physical form factor, intended for indoor mounting applications. This component serves as a dedicated solution for sub-GHz wireless communication protocols requiring reliable signal transmission in these specific licensed or unlicensed spectrum ranges.

Feature Summary

• Supports dual-frequency operation at 868 MHz and 900 MHz
• Utilizes a flat bar structural design for discreet installation
• Equipped with an integrated 2.5-meter coaxial cable assembly

Applications

• Sub-GHz IoT sensor networks
• Industrial telemetry systems
• Remote monitoring devices

Procurement Notes

Verify that the target application strictly requires the 868 MHz and 900 MHz bands to ensure compatibility. Confirm that the SMA male connector interface matches the receiving equipment port. Ensure the 2.5-meter cable length accommodates the spatial requirements between the antenna placement and the radio module without excessive strain or bending radius violations.

Selection Notes

Select this model when specific coverage of the 868 MHz and 900 MHz frequencies is mandatory. The flat bar profile is suitable for environments where low-profile mounting is preferred over omnidirectional rod designs. Consider the fixed cable length during system layout planning to avoid the need for additional extension cables.

Part Context

This component belongs to the Siretta ALPHA series, which focuses on specialized indoor antennas for cellular and IoT applications. Unlike broader multi-band models, this specific part number targets narrowband sub-GHz operations, distinguishing it from LTE or WiFi-centric variants within the manufacturer's portfolio.
