Overview
The Siretta ALPHA19/3M/SMAM/S/S/17 is an ultra-small square GPS antenna designed for precise location tracking. It features a 3-meter RG174 cable terminated with an SMA male connector for reliable RF transmission. The unit utilizes adhesive mounting for secure installation on various surfaces. Operating within the L1 band, it supports standard GNSS protocols to ensure accurate positioning data acquisition in mobile and fixed applications.
Feature Summary
- Ultra-compact square form factor optimized for space-constrained installations
- Adhesive backing enables permanent surface mounting without mechanical hardware
- Integrated 3-meter cable provides flexible routing distance from receiver
Applications
- Vehicle telematics and fleet tracking systems
- Portable GPS navigation devices
- IoT location sensors requiring compact footprint
Procurement Notes
Verify the specific ordering suffix matches the required cable length and connector type before purchase. Confirm that the SMA male interface is compatible with the target device's input port. Ensure the adhesive mounting surface is clean and suitable for long-term environmental exposure. Check RoHS compliance status if restricted substances are a project constraint.
Selection Notes
Select this model when a low-profile GPS solution is required for internal or external vehicle mounting. The 3-meter cable length offers significant flexibility compared to shorter variants. Consider the SMA male connector compatibility with existing harnesses. Evaluate the adhesive mount stability against vibration and temperature extremes relevant to the deployment environment.
Part Context
This component belongs to the Siretta ALPHA series of passive antennas. The series focuses on miniaturized designs for cellular and satellite navigation applications. The ALPHA19 variant specifically targets Global Positioning System requirements. It complements other Siretta products by providing specialized GNSS connectivity options.
Replacement Considerations
Direct substitutes include other Siretta ALPHA series GPS antennas with similar SMA connectors. Verify cable length and connector polarity when cross-referencing. Alternative brands may offer comparable performance but require interface adaptation.
