Overview
The Siretta DELTA12A/X/SMAM/S/S/17 is an omnidirectional flexi-rubber whip antenna designed for ISM band applications. It operates within the 433 MHz and 458 MHz frequency ranges, providing a gain of 3 dBi. The antenna features a quarter-wave physical structure with a length of 130 mm. It utilizes an SMA male connector for interface connectivity. Designed for direct installation, this component supports reliable wireless communication in industrial, scientific, and medical radio-frequency bands.
Feature Summary
- Omnidirectional radiation pattern ensures consistent signal coverage in all horizontal directions.
- Flexi-rubber whip construction allows for flexible positioning and durable mechanical performance.
- Quarter-wave design optimizes impedance matching for efficient RF energy transmission.
Applications
- Industrial control systems requiring 433 MHz or 458 MHz connectivity
- Scientific instrumentation operating in designated ISM bands
- Medical device telemetry and monitoring equipment
Procurement Notes
Verify that the required frequency range strictly matches 433 MHz or 458 MHz operations. Confirm the necessity of an SMA male connector interface for the host system. Ensure the 130 mm whip length fits within the available spatial constraints of the installation environment. Check for any specific environmental sealing requirements beyond standard flexi-rubber protection.
Selection Notes
Select this model when a compact, flexible antenna solution is needed for sub-1 GHz ISM bands. The 3 dBi gain offers a balance between size and performance for short-range applications. Consider the SMA male connector compatibility during system integration planning. Evaluate the 130 mm form factor against mounting space limitations before finalizing the procurement decision.
Part Context
This component belongs to the Siretta DELTA series, which specializes in antennas for ISM band applications. The DELTA12A variant specifically targets the 433/458 MHz frequencies using a flexi-rubber whip design. It complements other Siretta products by providing a low-profile, omnidirectional solution for industrial and scientific radio-frequency deployments.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Users must verify exact electrical and mechanical compatibility if considering alternative models from different manufacturers or series.
