PIS-0391

Antennas RF Overview

The PIS-0391 is a UHF ISM band LoRa whip antenna manufactured by Pi Supply, designed for the 860MHz to 930MHz frequency range with an 895MHz center frequency. It features a peak gain of 5.8dBi and supports a maximum power input of 20W. The antenna utilizes a straight, vertical form factor with N-type male connector termination and bracket mounting installation. Its physical height reaches a maximum of 800.00mm (31.496 inches). This component is specifically engineered for LoRa applications within the UHF spectrum.

Antennas RF Feature Summary

• Designed for LoRa communication protocols in the UHF ISM band
• Provides 5.8dBi peak gain for enhanced signal performance
• Features a robust 800mm vertical whip structure for optimal radiation
• Equipped with N-type male connector for secure RF interfacing

Antennas RF Applications

• LoRa network infrastructure deployment
• UHF ISM band wireless sensor networks
• IoT data collection systems operating at 868MHz or 895MHz
• Remote monitoring stations requiring high-gain directional transmission

Antennas RF Procurement Notes

Verify the specific manufacturing date code and connector integrity upon receipt, as the PIS-0391 may be subject to discontinuation status depending on supplier inventory cycles. Confirm that the N-type male interface matches the receiving equipment's port specifications. Ensure the 800mm mounting height clearance is available for the intended bracket installation location to prevent physical obstruction during operation.

Antennas RF Selection Notes

Select the PIS-0391 when a high-gain, vertically polarized solution is required for long-range LoRa links in the 860-930MHz range. Consider its substantial 800mm height and bracket mount requirement against space constraints. Compare against lower-profile alternatives if structural limitations exist, but prioritize this model for maximum gain requirements within the specified UHF ISM frequencies.

Antennas RF Part Context

Pi Supply manufactures specialized radio frequency components tailored for maker and industrial IoT projects. The PIS-0391 belongs to their dedicated LoRa antenna series, focusing on reliable connectivity for low-power wide-area networks. These products are typically distributed through electronic component channels rather than general consumer retail, targeting engineers integrating wireless telemetry into hardware designs.

Antennas RF Replacement Considerations

Public confirmed substitute part numbers include PIS-0938, PIS-0928, PIS-1120, and PIS-0935 from the same manufacturer. Verify frequency alignment and connector type compatibility before substituting.
