DCE-ANT2458-UFL

Antennas RF Overview

The DCE-ANT2458-UFL is a panel-mount RF antenna manufactured by TE Connectivity, designed for dual-band wireless applications. It operates across the 2.4 GHz and 5 GHz frequency ranges, specifically covering 2.4GHz ~ 2.485GHz and 4.9GHz ~ 5.85GHz. The component provides a gain of 12dBi at 2.4GHz and 15dBi at 5GHz. It features a U.FL (UMCC) or I-PEX MHF1 connector interface for signal transmission. The unit utilizes bracket mounting for secure installation in electronic enclosures.

Antennas RF Feature Summary

• Dual-band operation supporting both 2.4 GHz and 5 GHz wireless standards
• High directional gain for improved signal range and reliability
• Compact panel-mount design with integrated bracket for stable positioning

Antennas RF Applications

• Wi-Fi access points and routers
• Wireless LAN infrastructure equipment
• Industrial IoT gateways requiring dual-band connectivity
• Point-to-point wireless communication systems

Antennas RF Procurement Notes

Verify the specific connector type required, as the part may be available with U.FL or I-PEX MHF1 interfaces depending on the suffix. Confirm that the mounting bracket dimensions align with the target enclosure. Ensure the operating environment does not exceed the antenna's specified temperature ratings. Cross-reference the datasheet for impedance matching requirements to ensure compatibility with the host RF circuitry before finalizing procurement.

Antennas RF Selection Notes

Select this model when high-gain directional performance is required for both 2.4 GHz and 5 GHz bands simultaneously. The fixed polarization and panel-mount form factor make it suitable for stationary installations where orientation can be optimized. Consider the physical size constraints of the application, as the bracket mount requires adequate clearance. This component is appropriate for environments where external antennas are permitted and structural stability is prioritized over portability.

Antennas RF Part Context

This antenna belongs to TE Connectivity's Laird Signal Integrity portfolio, which focuses on reliable RF solutions for industrial and commercial electronics. The DCE series typically offers robust construction for consistent performance in demanding environments. As a passive RF component, it complements active transceivers by providing efficient radiation patterns without introducing active noise or power consumption into the system design.

Antennas RF Replacement Considerations

Direct substitutes include other TE Connectivity dual-band panel antennas such as the DCE-ANT2412-UFL for single-band 2.4 GHz needs or the DCE-ANT5819-UFL for 5 GHz only applications. Verify that any replacement maintains the same connector interface and mounting style to avoid mechanical redesign. Check if alternative models offer comparable gain figures to ensure no degradation in link budget performance.
