S1551AH-915S

Antennas RF Overview

The S1551AH-915S is a swivel whip antenna manufactured by Nearson Inc., designed for operation within the UHF frequency range. It operates specifically in the 902-928 MHz band, which corresponds to the 915 MHz ISM allocation. The component features a tilt or swivel mechanism allowing for directional adjustment and utilizes an RP-SMA male connector for interface. It provides a gain of 2 dBi and is constructed as a robust RF antenna suitable for wireless communication applications requiring reliable signal transmission in this specific frequency group.

Antennas RF Feature Summary

• Swivel design enabling adjustable orientation
• RP-SMA male connector interface
• Optimized for 902-928 MHz ISM band

Antennas RF Applications

• UHF wireless communication systems
• ISM band data transmission devices
• RF equipment requiring directional antenna adjustment

Antennas RF Procurement Notes

Verify the exact connector gender and mechanical dimensions against the official Nearson datasheet before integration. Confirm RoHS compliance status if required by your manufacturing standards. Ensure the RP-SMA interface matches the host device port. Check lead times as they may vary based on manufacturer availability.

Antennas RF Selection Notes

Select this model when a fixed whip antenna is insufficient due to line-of-sight constraints. The swivel feature allows for fine-tuning signal directionality. Ensure the operating environment supports the UHF frequency range and that the 2 dBi gain meets system link budget requirements without excessive size.

Antennas RF Part Context

This part belongs to Nearson's RF antenna portfolio, specifically the swivel whip series. It shares functional similarities with other models like the T6155AM-LTE-S but is distinct in its specific 915 MHz tuning and mechanical tilt configuration. It serves as a specialized component for UHF applications rather than a general-purpose broadband antenna.

Antennas RF Replacement Considerations

Direct substitutes include the T6155AM-LTE-S for similar swivel functionality in the same band. Verify compatibility with the S463AH-915 if a straight mount is acceptable instead of swivel. Always cross-reference connector types and mounting styles before swapping.
