Overview
The Siretta DELTA5A/X/SMAM/RP/S/17 is a passive, omnidirectional WiFi antenna designed for external installation. It operates within the 2.4 GHz frequency band and features a short stubby physical form factor with an internal quarter-wave dipole structure. The unit includes a direct mounting option and utilizes an SMA male connector with reverse polarity (RP) interface. This component serves as a dedicated wireless connectivity solution for applications requiring reliable 2.4 GHz signal transmission and reception.
Feature Summary
- Omnidirectional radiation pattern ensures consistent signal coverage in all horizontal directions
- Short stubby physical design facilitates discreet and compact external mounting
- Integrated quarter-wave dipole construction provides efficient passive signal handling
- Reverse polarity SMA male connector ensures secure and standardized RF interfacing
Applications
- External WiFi network infrastructure deployment
- Wireless local area network (WLAN) signal extension
- IoT device connectivity modules operating at 2.4 GHz
- Industrial wireless sensor network installations
Procurement Notes
Verify that the target system utilizes SMA Reverse Polarity (RP) connectors to ensure mechanical compatibility. Confirm that the application environment supports external antenna mounting and does not require indoor-rated components. Check that the operational frequency aligns strictly with the 2.4 GHz specification. Ensure cable assemblies match the RP gender configuration to prevent connection failure.
Selection Notes
Select this model when a dedicated 2.4 GHz external WiFi solution is required rather than a combined cellular-WiFi unit. Choose this part for applications needing a low-profile, stubby form factor instead of whip or panel styles. Opt for this specific reverse polarity variant if the host equipment mandates RP interfaces. Consider this passive component for environments where active amplification is unnecessary.
Part Context
This component belongs to the Siretta DELTA series, which specializes in compact, high-performance wireless antennas. The DELTA5A variant specifically targets the 2.4 GHz ISM band, distinguishing it from multi-band cellular models like the Tango series or GPS-specific Delta units. It complements Siretta's portfolio by providing focused RF solutions for Wi-Fi and Bluetooth protocols.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing SMA RP interfaces before considering alternative brands. No direct cross-reference data is documented for this specific model configuration.
