Antennas RF datasheet and documents for OSCAR1A/5M/SMAM/S/S/31
Antennas RF Overview
The Siretta OSCAR1A/5M/SMAM/S/S/31 is a broadband whip antenna designed for bracket mounting. It operates across five frequency bands: 850MHz, 900MHz, 1.8GHz, 1.9GHz, and 2.1GHz. The unit features an SMA male connector and provides 5dBi gain with a VSWR of 1.8. It includes a 5-meter cable length.
Antennas RF Feature Summary
- Broadband operation supporting multiple cellular standards
- High gain omnidirectional radiation pattern
- Robust whip design for reliable signal transmission
Antennas RF Applications
- GPRS networks
- GSM systems
- UMTS deployments
Antennas RF Procurement Notes
Verify the specific manufacturer origin, as this part number appears in catalogs from both Siretta Ltd and Trompeter (Cinch Connectivity Solutions). Confirm that the SMA male connector polarity and 5-meter cable length match the system requirements before finalizing the order to ensure compatibility.
Antennas RF Selection Notes
Select this model when a high-gain omnidirectional solution is required for mobile broadband applications. The 5-meter cable offers flexibility for remote antenna placement relative to the radio unit. Ensure the mounting bracket supports the physical dimensions and weight of the whip assembly.
Antennas RF Part Context
This component belongs to the OSCAR series of directional and omnidirectional antennas. It is specifically engineered for wideband coverage, distinguishing it from narrowband cellular variants. The design prioritizes consistent performance across the specified UHF and lower microwave frequency ranges.
Antennas RF Replacement Considerations
OSCAR1A/10M/SMAM/S/S/31 serves as a direct substitute with identical electrical characteristics but features a 10-meter cable instead of 5 meters. Other variants in the family may differ by connector type or cable length.
