DCE-ANT2458-ASSY

Antennas RF Overview

The DCE-ANT2458-ASSY is an RF antenna assembly manufactured by TE Connectivity, designed for dual-band wireless communication applications. It operates within the 2.4 GHz ISM band (2.4GHz ~ 2.485GHz) and the 5 GHz UNII band (4.9GHz ~ 5.85GHz). The unit provides a gain of 12 dBi at 2.4 GHz and 15 dBi at 5 GHz. It features a panel mount configuration with an integrated U.FL (UMCC) or I-PEX MHF1 connector interface. The assembly includes an 8-inch cable length for flexible installation positioning relative to the host device.

Antennas RF Feature Summary

• Dual-band operation supporting both 2.4 GHz and 5 GHz frequency ranges for versatile wireless connectivity.
• High directional gain characteristics optimized for extended range performance in industrial environments.
• Integrated U.FL connector interface simplifies connection to compatible RF modules without soldering.

Antennas RF Applications

• Industrial IoT sensor nodes requiring robust long-range telemetry
• Wireless local area network (WLAN) access points
• Medical equipment with wireless data transmission capabilities

Antennas RF Procurement Notes

Verify that the specific revision of the DCE-ANT2458-ASSY matches the required connector type and cable length specifications for your design. Confirm compatibility with the operating frequency bands of your target application. Ensure that the mounting bracket dimensions align with your enclosure constraints. Request updated datasheets from authorized distributors to confirm current manufacturing status and lead times before finalizing procurement plans.

Antennas RF Selection Notes

Select this model when high-gain directional performance is required for both 2.4 GHz and 5 GHz bands. Consider the fixed 8-inch cable length and panel mount style during mechanical integration. Evaluate the U.FL connector mating cycle limits if frequent disconnection is anticipated. Compare against lower-gain omnidirectional alternatives if spatial constraints are severe.

Antennas RF Part Context

This component belongs to TE Connectivity's Laird Connectivity antenna portfolio, specifically engineered for enterprise and industrial networking solutions. It complements other antennas in the series that may offer different form factors or connector types while maintaining similar electrical performance profiles for dual-band Wi-Fi and Bluetooth Low Energy applications.

Antennas RF Replacement Considerations

Direct substitutes include the DCE-ANT2458-UFL variant, which shares identical electrical specifications but may differ in packaging or accessory inclusion. Verify that any replacement maintains the same gain values and frequency coverage to ensure system performance consistency.
