Overview

The ANT-433-CW-QW is a 1/4-wave whip antenna designed for 433MHz ISM band applications. It features a rugged, flexible design with a 173mm length and an RP-SMA male connector, making it suitable for compact wireless devices requiring external antenna mounting.

Why Choose This Part

This antenna offers a high 3.3dBi peak gain and a low VSWR of less than 1.9 at center frequency. Its flexible whip construction resists mechanical stress and impact, while the RP-SMA connector ensures secure attachment to standard RF bulkheads.

Applications

Security and Alarm Systems
Reliable signal transmission for wireless intrusion sensors and alarm control panels in the 433MHz band.
Remote Control Systems
Effective for garage door openers, gate controllers, and industrial remote activation switches.
Smart Home Automation
Integrates into lighting controllers and environmental sensors utilizing sub-GHz ISM communication.
Industrial Telemetry
Used for low-speed wireless data monitoring in industrial environments across the 400MHz to 470MHz range.
