Overview
The Siretta TANGO3/1M/SMAM/S/S/31 is a stubby, omnidirectional RF whip antenna designed for dual-band wireless applications. It operates within the 900 MHz and 1.8 GHz frequency ranges, covering specific bands such as 824–960 MHz and 1.71–2.17 GHz. The unit features a 50-ohm input impedance and includes a 1-meter cable length terminated with an SMA male connector. Constructed for panel mounting, this antenna provides reliable signal transmission for mobile communication protocols.
Feature Summary
- Dual-band operation supporting 900 MHz and 1.8 GHz frequencies
- Stubby omnidirectional whip design for compact integration
- SMA male connector termination with 1-meter lead length
Applications
- GPRS networks
- GSM systems
- UMTS applications
Procurement Notes
Verify the exact part number against official Siretta documentation to ensure compatibility with your specific frequency requirements. Confirm that the SMA male connector matches your device interface. Check for RoHS compliance status if environmental regulations apply to your project. Ensure the panel mounting style fits your enclosure design constraints before finalizing procurement.
Selection Notes
Select this model when a low-profile, omnidirectional solution is required for dual-band cellular or data communications. The 1-meter cable offers flexibility in placement relative to the host device. Consider the VSWR and gain specifications from the datasheet to ensure adequate signal performance for your specific deployment environment and range requirements.
Part Context
This component belongs to the Siretta Tango series, which specializes in rugged, multi-band antennas for industrial and mobile communications. The Tango line typically features durable construction suitable for harsh environments, often including IP-rated variants. This specific model represents a standard configuration within that portfolio, focusing on essential dual-band functionality.
Replacement Considerations
Direct substitutes include other Tango series models with similar frequency coverage, such as TANGO3/0.5M/SMAM/S/S/31 or TANGO3/3M/SMAM/S/S/31, differing primarily in cable length. Verify connector polarity and mounting type when considering alternatives from other manufacturers.
