Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance status and exact frequency range coverage. Ensure the BNC male connector matches the receiving equipment interface. Confirm that the 3-meter cable length meets spatial requirements. Check adhesive backing integrity for the intended mounting surface material before procurement.
Selection Notes
Select this model when a compact, low-profile antenna solution is required for indoor or panel-mounted installations. The integrated cable simplifies routing compared to discrete antennas. Verify that the 2.4 GHz dual-band performance aligns with the target protocol requirements. Consider the BNC connector type for compatibility with existing base station or router interfaces.
Part Context
This component belongs to the Siretta Alpha series of RF antennas. It is engineered for wireless communication environments requiring reliable signal transmission in the sub-GHz and 2.4 GHz bands. The product line emphasizes ease of installation through adhesive mounting options.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Evaluate other Siretta T-bar models with similar connector types and cable lengths if sourcing constraints exist.
