Product Introduction
Wide - band Frequency Coverage：The GL - SD90GSM7 antenna operates in the 900 - 1800MHz frequency range. This wide - band design makes it suitable for a diverse range of applications, providing flexibility for various wireless communication needs. It can support different wireless systems operating within this spectrum, such as GSM networks, some wireless broadband applications, and industrial wireless devices.
High Gain for Extended Range：With a gain of 7.5dBi, the antenna can effectively strengthen signals. High gain is crucial for extending the communication range, allowing devices to connect over longer distances. This is especially useful in areas where signal strength is a concern, like remote locations or areas with weak network coverage.
Stable Impedance and Low VSWR：It 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, reducing signal reflection and improving the overall signal quality. This combination results in a more stable and reliable connection.
Vertical Polarization for Reduced Interference：The vertical polarization of the GL - SD90GSM7 helps to minimize interference from horizontally polarized signals. In environments with a lot of electromagnetic clutter, such as urban areas or near large - scale electrical equipment, this polarization type ensures a more stable communication link. It allows for better signal reception and transmission, even in challenging electromagnetic environments.
Durable Construction and Wide - range Operation：Made of steel radome material, the GL - SD90GSM7 is durable and can withstand various environmental conditions. Steel provides excellent protection for internal components, making the antenna suitable for both indoor and outdoor use. With a weight of 0.3 kg and a height of 370mm, it is relatively compact and easy to install. Additionally, it can operate in a temperature range of - 40℃ to 80℃, making it adaptable to different climates and environments.
Application scenarios
Cellular Network Expansion – Boosts signal for remote GSM towers.
Industrial IoT Systems – Supports reliable data transmission in factories.
Marine Communication – Weatherproof design suits boats and coastal setups.
