ANT-433-CW-HW
Overview
The ANT-433-CW-HW is a high-performance 1/4-wave monopole whip antenna designed for 433MHz ISM band applications. This antenna provides a compact, tiltable form factor with an integrated RP-SMA connector, making it suitable for remote control and security system hardware. It features a center frequency of 433MHz with a bandwidth optimized for the 418MHz to 448MHz range.
Why Choose This Part
This antenna offers a professional-grade VSWR of less than 2.0 and a 1.1dBi gain, ensuring efficient power transfer. Its tilt and swivel mechanism allows for flexible positioning to optimize signal polarization in diverse mounting environments. The durable overmolded design supports a wide operating temperature range from -20C to +85C.
Applications
Key Specifications
Getting Started
To achieve specified performance, mount this antenna on a conductive metal ground plane to serve as the second half of the monopole. Ensure the RP-SMA connector is torqued correctly to maintain signal integrity and prevent mechanical failure. Use low-loss 50-ohm coaxial interconnects if the antenna is being remoted from the PCB.
