ANT-418-WRT-SMA

Antennas RF Overview

The ANT-418-WRT-SMA is a compact, dome-style RF antenna manufactured by TE Connectivity Linx Technologies. Designed for Sub-GHz applications, it operates at a center frequency of 418 MHz with a specified range of 393 MHz to 443 MHz. The component features an RP-SMA male connector and utilizes panel mount installation. It provides a gain of -1.8 dBi and maintains a Voltage Standing Wave Ratio (VSWR) of 2. The antenna is constructed for surface-mount or panel integration within alarm, ISM, remote control, and security systems.

Antennas RF Feature Summary

• Compact dome form factor designed for space-constrained installations
• Integrated RP-SMA male connector for direct cable attachment
• Optimized performance across the 393 MHz to 443 MHz frequency band
• Linear polarization suitable for standard Sub-GHz communication protocols

Antennas RF Applications

• Wireless alarm systems
• Industrial, Scientific, and Medical (ISM) equipment
• Remote control devices
• Security system transceivers

Antennas RF Procurement Notes

Verify the specific connector variant, as datasheets may list RP-SMA or SMA configurations depending on the exact suffix. Confirm mechanical mounting requirements against the target enclosure design. Ensure the operating environment aligns with the component's temperature ratings. Cross-reference the manufacturer's latest documentation for any recent specification updates or compliance changes before finalizing procurement orders.

Antennas RF Selection Notes

Select this model when a low-profile, dome-shaped antenna is required for Sub-GHz frequencies. It is appropriate for designs prioritizing aesthetic integration and compact footprints over high-gain performance. Consider the -1.8 dBi gain limitation relative to whip or helical alternatives. Verify compatibility with the host device's RF interface and available mounting space.

Antennas RF Part Context

This component belongs to the ANT-418 family from TE Connectivity Linx, which offers various antenna solutions for the 418 MHz frequency band. The family includes chip antennas, helical designs, and whip styles. The WRT series specifically addresses needs for compact, non-intrusive mounting solutions in consumer and industrial electronics requiring reliable Sub-GHz connectivity.

Antennas RF Replacement Considerations

Direct substitutes include other models within the ANT-418 series such as the ANT-418-CW-HD or ANT-418-PW-LP, provided the mechanical form factor and connector type are compatible with the existing design. Alternative manufacturers offering similar Sub-GHz dome antennas may require schematic and layout adjustments.
