• IoT sensor networks

Antennas RF Procurement Notes

Verify the specific connector type against project requirements, as sources indicate both SMA and RP-SMA male options for similar models. Confirm the exact gain specification, as documentation varies between 1dBi, 2.5dBi, and 2dBi. Ensure the physical dimensions align with the available height specifications of 8.035 inches or 8.789 inches depending on the specific variant configuration.

Antennas RF Selection Notes

Select this component for applications requiring a robust, weather-resistant antenna for the 868 MHz ISM band. The tilt feature allows for optimized signal directionality without mechanical adjustment of the base. Verify compatibility with the host device's connector gender and impedance matching before integration.

Antennas RF Part Context

This model belongs to the Nearson Inc. S1551 series of RF antennas. It is part of a family that includes variants for different frequencies, such as the S1551AH-915S for the 902-928 MHz range. These antennas are generally characterized by their whip design and connector mount style suitable for industrial and commercial wireless applications.

Antennas RF Replacement Considerations

The S1551AH-915S is a related model within the same series but operates at 902-928 MHz. Substitution requires verification of frequency band compatibility and connector type consistency. No other direct substitute part numbers are confirmed in the provided documentation.
