Product Introduction
Broad Frequency Band：The GL - SD433M antenna covers the 433 - 868MHz frequency range, making it versatile for a wide range of applications. This broad - band functionality allows it to be used in various wireless communication systems operating within this spectrum, providing flexibility for different user needs.
High Gain for Strong Signals：With a gain of 5dBi, the GL - SD433M can effectively boost weak signals. This high - gain feature extends the communication range, enabling devices to connect over longer distances. It is especially useful in areas with weak signal coverage or for applications that require reliable long - range communication.
Stable Impedance and Low VSWR：The antenna has an impedance of 50Ω and a VSWR of ≤1.5. A stable 50Ω impedance ensures efficient power transfer between the antenna and connected devices. The low VSWR indicates good impedance matching, which reduces signal reflection and improves the overall signal quality, resulting in a more stable connection.
Vertical Polarization for Reduced Interference：The vertical polarization of the GL - SD433M helps to minimize interference from horizontally polarized signals. This is particularly beneficial in environments with a lot of electromagnetic clutter, such as urban areas or industrial settings. It ensures a more stable and reliable communication link, even in challenging conditions.
Durable Construction and Wide - range Operation：Made of ABS/Steel radome material, the GL - SD433M is durable and can withstand various environmental conditions. It has a weight of 0.23 kg and a height of 170mm, making it relatively compact and easy to install. Additionally, it can operate in a temperature range of - 40℃ to 80℃, making it suitable for use in different climates and environments.
Wireless Sensor Networks：In industrial monitoring systems, smart agriculture, or environmental sensing applications, wireless sensor networks often operate in the 433 - 868MHz band. The GL - SD433M can be used to enhance the signal strength between sensors and the data - collection hub, ensuring accurate and timely data transmission.
Home Automation：For home automation devices like smart thermostats, doorbell cameras, and smart locks that communicate wirelessly in the 433 - 868MHz frequency range, the GL - SD433M can improve the reliability of the connection. It helps create a seamless and responsive home automation ecosystem.
Remote Control Devices：Many remote - controlled devices, such as garage door openers, toy cars, and some security alarm systems, use the 433 - 868MHz band. The GL - SD433M can be installed on these devices to extend the control range and reduce signal dropouts, providing a better user experience.
Wireless Surveillance Systems：In wireless security camera systems operating in the 433 - 868MHz range, the GL - SD433M can be used to improve the signal quality between cameras and the monitoring station. This ensures that video footage is transmitted smoothly, enhancing the effectiveness of the surveillance system.
Industrial Wireless Communication：Industries that rely on wireless communication for equipment control and monitoring can benefit from the GL - SD433M. It can be installed on wireless sensors, actuators, and control units to improve the signal strength and reliability of communication, enabling efficient industrial operations.
