14875

Antennas RF Overview

The SparkFun WRL-14875 is a quarter-wave rubber duck antenna designed for LoRa and other ISM band communications operating within the 860MHz to 960MHz frequency range. It features a center frequency of 915MHz with a gain of 2dBi. The component utilizes an RP-SMA connector for mounting and connection, providing a compact solution for wireless data transmission applications requiring reliable RF performance in the sub-GHz spectrum.

Antennas RF Feature Summary

• Quarter-wave rubber duck design optimized for compact installations
• Operates effectively across the 860MHz to 960MHz ISM band
• Features a 2dBi gain rating for standard signal strength
• Equipped with an RP-SMA connector for secure attachment

Antennas RF Applications

• LoRaWAN sensor node connectivity
• Sub-GHz wireless telemetry systems
• IoT device communication modules
• Remote monitoring equipment antennas

Antennas RF Procurement Notes

Verify that the receiving equipment supports the RP-SMA interface type. Confirm operational frequency requirements align with the 860-960MHz range. Ensure mechanical clearance accommodates the physical dimensions of the quarter-wave rubber duck form factor before integration into the final enclosure design.

Antennas RF Selection Notes

Select this antenna when a low-profile, omnidirectional solution is required for sub-GHz frequencies. It is suitable for applications where space constraints prevent the use of larger whip antennas but still demand reliable 2dBi gain. Consider environmental exposure ratings if deployed outdoors.

Antennas RF Part Context

This component belongs to SparkFun's RF Antennas category, specifically targeting developers working with LoRa and similar long-range, low-power wireless protocols. It serves as a hardware accessory to facilitate wireless communication capabilities in embedded projects and prototype boards.

Antennas RF Replacement Considerations

No direct public substitute part numbers are confirmed in official documentation. Alternative selection requires matching the RP-SMA connector, 915MHz center frequency, and 2dBi gain specifications.
