Product Description
When 433MHz links begin to drop packets due to distance, building obstacles, or low transmit power at the endpoint, increasing bidirectional signal strength is often the most direct fix. This 433MHz 20W Signal Booster is designed to reinforce both the uplink and downlink paths in utility metering, long-range telemetry, industrial IoT, and remote control systems. It provides balanced TX and RX amplification in a compact aluminum housing, with SMA female connectors and a wide 12-24V DC input for straightforward integration into existing radio modems, gateways, and field equipment. The 5.5*2.1mm power socket is common in industrial and portable installations. When link budget is the limiting factor, this booster restores reliable RF headroom across the 433.05-434.79MHz band.
Typical Applications
- Utility Metering & AMR/AMI: Strengthen two-way data links for smart meters and automatic reading infrastructure.
- Long-Range Telemetry & SCADA: Reinforce uplink and downlink signals for remote monitoring and control.
- Industrial IoT Sensor Networks: Extend coverage for low-power sensors, actuators, and industrial controllers.
- UAV Remote Control & Telemetry: Improve 433MHz command and telemetry link stability for extended-range operations.
- Wireless Alarm & Access Systems: Enhance signal reliability for security panels, access control, and automation devices.
- Licensed 433MHz Field Testing: Support higher bidirectional output for RF experimentation and validation.
