Designed for iot / m2m, the AW-RD0433-3 is a 428-438 MHz rubber duck / terminal antenna rated at 3 dBi. Its vertical polarization and tuned matching network keep return loss low across the full operating band.
Radiation Pattern and Gain
As an omnidirectional radiator, it provides a full 360 degree azimuth pattern with an approximate 55 degree elevation beamwidth, distributing energy evenly around the mast. The rated gain of 3 dBi is referenced to an isotropic radiator.
Mechanical and Electrical Specifications
Mechanically, the AW-RD0433-3 measures 210 x 13 x 13 mm and is housed in a TPE jacket. The standard interface is a SMA-Male connector, with a nominal impedance of 50 ohms and a typical VSWR of 1.5:1 or better. The element withstands up to 100 W of input power.
Installation Guidance
The recommended installation is desktop / handheld. The enclosure carries an IP40 environmental rating for outdoor exposure. For best results, mount the antenna with clear line of sight to the served area and bond all outdoor hardware to a proper grounding system.
Typical Applications
IoT / M2M
Handheld Radio
CPE / Subscriber Units
