Overview

The ANT-433-CW-HW-SMA is a 1/4-wave monopolar whip antenna designed for reliable performance in the 433MHz ISM band. It features a rugged, overmolded jacket and a straight SMA male connector for direct mounting to equipment enclosures. This antenna is optimized for a frequency range of 418MHz to 448MHz, making it suitable for regional unlicensed wireless standards.

Why Choose This Part

The HW series antenna offers a compact 120mm profile with a 2.0 maximum VSWR, ensuring efficient power transfer. Its internal helical element provides a balance between size and performance for fixed-frequency applications. The SMA male termination allows for a secure, threaded connection that withstands vibrations in industrial environments.

Applications

Remote Keyless Entry
Ideal for 433MHz RKE systems and remote control transmitters requiring a durable external antenna.
Home Automation
Used in smart home hubs and security sensors that communicate over the 433MHz ISM band.
Industrial Telemetry
Suitable for long-range sensor nodes and industrial monitoring systems operating in the UHF frequency group.
Security Systems
Integrates into alarm panels and wireless security detectors for robust signal propagation.

Getting Started

Ensure your PCB layout includes a sufficient ground plane, as this 1/4-wave antenna requires it for proper operation. When mounting, keep the antenna clear of nearby metal obstructions to maintain the 0dBi gain and radiation pattern. Match the connector on your enclosure to the SMA male termination for a low-loss RF path.
