Product Overview

The TX433-TH-3 Spring Antenna launched by Chengdu Ebyte Electronic Technology Co., Ltd. is a miniaturized antenna specifically designed for 433MHz wireless communication devices. Featuring gold-plated copper material and a silver finish, it combines durability with signal stability, making it ideal for industrial IoT, smart home, wireless sensors, and other scenarios, providing reliable long-distance data transmission support for devices.

Core Parameters & Technical Advantages

  1. Precise Matching for 433MHz Band

    • Strictly locked to 433MHz frequency, perfectly compatible with mainstream LoRa, data transmission radio, and other devices, avoiding communication attenuation caused by frequency mismatch.

    • 50Ω impedance, consistent with most wireless modules, ensuring efficient signal transmission and reducing energy loss.

  2. Miniaturized & High-Reliability Design

    • Ultra-small Size: With a coil diameter of 5.5mm, wire diameter of 0.8mm, and total length of only 37mm, it can be easily embedded into space-constrained devices (e.g., sensor nodes, portable terminals).

    • Gold-plated Copper Material: Strong oxidation resistance, low signal attenuation rate during long-term use, and adaptable to industrial environments from -40℃ to +85℃.

  3. Stable Signal Performance

    • Antenna gain of 1dBi, effectively extending communication distance in open environments; optimized impedance matching via Smith chart, with excellent Voltage Standing Wave Ratio (VSWR) performance (tested in open air).

    • Welding-type interface design for secure installation, avoiding signal interruption due to poor contact.

Application Scenarios & Installation Recommendations

  • Industrial IoT: Wireless sensor data collection, PLC remote control, smart meter data transmission.

  • Smart Home: Signal relay for smart door locks, temperature/humidity sensors, and lighting control systems.

  • Outdoor Devices: Agricultural monitoring equipment, environmental monitoring stations, and UAV data links.

Installation Notes:

  • Keep the antenna away from metal objects or enclosures to avoid signal shielding.

  • Recommended installation height ≥1 meter to reduce ground absorption effects.

  • Ensure the antenna direction aligns with the communication target; vertical installation optimizes signal radiation range.
