66089-0806

Antennas RF Overview

The 66089-0806 is a straight whip RF antenna manufactured by TTM Technologies, Inc. Designed for the UHF frequency band, it operates at a center frequency of 866 MHz with a bandwidth covering 865 to 868 MHz. The component provides a peak gain of 3 dBi and maintains a Voltage Standing Wave Ratio (VSWR) of 1.7. It utilizes a U.FL (UMCC) or I-PEX MHF1 connector for board mounting. The physical height of the antenna is specified as 2.362 inches (60.00 mm).

Antennas RF Feature Summary

• Straight whip design optimized for vertical polarization in compact form factors.
• Integrated U.FL (UMCC) and I-PEX MHF1 compatible connector interface for direct PCB attachment.
• Engineered for stable performance within the 865 to 868 MHz sub-GHz frequency range.

Antennas RF Applications

• Sub-GHz wireless communication modules
• Industrial telemetry systems
• Remote monitoring devices

Antennas RF Procurement Notes

Verify that the receiving PCB footprint strictly supports the U.FL (UMCC) or I-PEX MHF1 connector type to ensure mechanical compatibility. Confirm that the operating environment does not exceed the thermal limits defined in the official datasheet. Check for RoHS compliance status if required by specific regional regulations before finalizing procurement orders.

Antennas RF Selection Notes

Select this model when a low-profile, vertically polarized antenna is required for sub-GHz applications near 866 MHz. Ensure the host device allows sufficient clearance above the ground plane to accommodate the 60.00 mm height without obstruction. Verify that the connector type matches the available RF port on the target circuit board.

Antennas RF Part Context

This component belongs to the 66089 series of RF antennas from TTM Technologies, Inc., which specializes in radio frequency components and printed circuit boards. The series includes variants tuned for different frequency bands, such as the 2.4 GHz 66089-2430. This specific part addresses the need for reliable signal transmission in industrial and IoT sectors using sub-GHz frequencies.

Antennas RF Replacement Considerations

The 66089-2430 serves as a functional substitute within the same product family but operates at 2.4 GHz rather than 866 MHz. Other models in the 66089 series may offer similar mechanical profiles but require verification of frequency alignment and connector compatibility before implementation.
