Description

The TX433-XPA100 is a professional-grade 433MHz antenna engineered for reliable performance in the license-free ISM band. Its omnidirectional radiation pattern ensures consistent coverage for systems like wireless sensor networks, remote controls, and industrial telemetry links. The antenna is built with a durable ABS radome and a metal magnetic base, offering both mechanical protection and versatile installation options.

Designed for system integrators and RF engineers, this antenna comes with a 1-meter low-loss feeder cable terminated with a standard SMA-male connector, simplifying integration with common RF modules and development boards. Its electrical specifications, including a VSWR of less than 1.5 and 50-ohm impedance, ensure efficient power transfer and minimal signal reflection for optimized RF performance.

Key Features

  • Magnetic Mounting Convenience – The integrated magnetic base provides a strong hold on vehicle roofs, control cabinets, or any metal surface for optimal signal placement.
  • Omnidirectional Vertical Polarization – Delivers uniform horizontal coverage, making it ideal for applications where the transmitter or receiver orientation is variable.
  • Wide Operational Tolerance – Functions reliably across an extended temperature range from -20°C to 65°C and 5% to 95% humidity.
  • Durable Construction – Features a robust ABS plastic radome and a metal base, ensuring longevity in both indoor and outdoor environments.
  • Pre-Assembled Cable Assembly – Includes a 100cm (1-meter) coaxial cable with a rotatable SMA male connector, ready for immediate deployment.

Applications

  • Industrial Wireless Telemetry – Connects to 433MHz transceivers for monitoring sensors, PLCs, and equipment status in SCADA systems.
  • Remote Control Systems – Used in long-range RF remote controls for gates, industrial machinery, and robotic applications.
  • Wireless Sensor Networks – Extends the range of 433MHz sensor nodes for environmental monitoring, smart agriculture, and building automation.
  • Amateur Radio & Hobbyist Projects – A reliable antenna for ham radio operators and makers working with Arduino, Raspberry Pi, or dedicated RF modules in the 433MHz band.

Frequently Asked Questions

What is the typical range I can expect with this 433MHz antenna?

Range depends heavily on transmitter power, receiver sensitivity, and environment. With a typical 1W (30dBm) transmitter and clear line-of-sight, this 3dBi antenna can achieve several hundred meters to over a kilometer. In urban or obstructed areas, range will be reduced. For best results, ensure the antenna is mounted vertically and as high as possible, using the magnetic base on a metal surface as a ground plane.

Can I use this antenna with my LoRa or RFM69 module?

Yes, if your module operates in the 433MHz ISM band. Many LoRa (e.g., SX1276/78) and RFM69HCW modules support 433MHz. Ensure your module has a matching SMA female connector or use an appropriate adapter (e.g., SMA to u.FL/IPEX). The antenna's 50-ohm impedance and 433MHz center frequency are compatible, but verify your specific module's frequency range covers 433MHz ± 15MHz for optimal performance.

How do I properly install and orient the antenna?

For omnidirectional coverage, mount the antenna vertically. Use the magnetic base to attach it to a central, elevated metal surface like a control box or vehicle roof, which acts as a ground plane. Route the 1-meter cable without sharp bends to avoid signal loss. Securely screw the SMA male connector onto your device's female port, hand-tightening until snug. Avoid placing the antenna near large metal obstructions or inside enclosures for best signal radiation.
