Overview
The Siretta TANGO9/1.5M/SMAM/S/S/20 is a multi-band omnidirectional whip antenna designed for the 433 MHz ISM band. It features a straight physical form factor with a 1.5-meter cable length and an SMA male connector. The unit provides a gain of 3 dBi and supports a maximum power rating of 20 W. Installation is facilitated through a through-hole mounting type. The component operates within the UHF frequency group, specifically targeting applications requiring reliable signal transmission in the 433 MHz range.
Feature Summary
- Omnidirectional radiation pattern ensures consistent signal coverage across all horizontal angles.
- Integrated 1.5-meter cable allows flexible positioning between the antenna element and the RF interface.
- Through-hole mounting configuration provides secure mechanical attachment to equipment surfaces.
Applications
- ISM band wireless sensor networks
- Industrial telemetry systems
- Remote monitoring devices
Procurement Notes
Verify that the SMA male connector polarity matches the receiving port on the target device. Confirm that the through-hole mounting dimensions align with the chassis or PCB layout specifications. Ensure the 20 W power rating exceeds the maximum output of the connected transmitter to prevent component damage during operation.
Selection Notes
Select this model when a dedicated 433 MHz solution is required rather than a multi-band alternative. The fixed 1.5-meter cable length dictates installation geometry constraints. Consider the 3 dBi gain level against environmental interference requirements. This specific part number includes the defined cable length and connector type without modification options.
Part Context
This component belongs to the Tango series of antennas manufactured by Siretta Ltd. The series encompasses various configurations tailored for different frequency bands and mounting requirements. The Tango 9 variant specifically addresses the 433 MHz ISM allocation, distinguishing it from cellular or GPS-focused models within the broader product portfolio.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the SMA male connector, 433 MHz frequency support, and through-hole mounting style.
