Overview

The ANT-433-CW-QW-SMA is a 1/4-wave whip antenna designed for 433MHz ISM band applications. This straight dipole antenna features an SMA male connector and provides a peak gain of 3.3dBi for reliable long-range sub-GHz communication. It is specifically tuned for a frequency range of 400MHz to 470MHz with a VSWR of 1.9.

Why Choose This Part

The 1/4-wave design offers a balance of compact size and high 3.3dBi gain for improved signal penetration. Its rugged whip construction ensures durability in industrial environments while the standard SMA connector simplifies mechanical integration with common RF enclosures.

Applications

Security Systems
Ideal for wireless alarm panels and entry sensors requiring stable 433MHz links.
Industrial Remote Control
Used in heavy machinery wireless controllers and overhead crane remotes.
Smart Home Hubs
Acts as the primary antenna for gateways communicating with low-power 433MHz peripherals.
Long Range ISM Links
Suitable for data telemetry and outdoor sensor networks utilizing the UHF band.

Getting Started

Ensure the antenna is mounted on a metal ground plane of at least 10cm x 10cm to achieve the rated 1/4-wave performance. Connect to any 50-ohm SMA female bulkhead or PCB connector, ensuring the VSWR is verified in the final enclosure to account for nearby metallic interference.

Also Consider
