4G Magent antenna Magentic Base 37mm Diameter GL-DY828

Product Introduction

1. Wide Frequency Range: The GL - DY828 4G Magnet Antenna covers a broad frequency range of 800 - 960/1710 - 2700MHz. This wide - band design makes it suitable for various 4G networks, ensuring compatibility with different carriers and regions. It can support multiple frequency bands used in 4G communication, providing users with reliable connectivity across different network environments.

2. Good Gain Performance: With a gain of at least 4.0 dBi, the antenna can effectively enhance the signal strength. A higher gain means better signal reception and transmission capabilities, which is crucial for extending the communication range. Whether you are in a remote area or an area with weak network coverage, this antenna can help improve the quality of your 4G connection.

3. Stable Electrical Characteristics: It has a VSWR of ≤2.0 and a normal impedance of 50Ω. The low VSWR indicates good impedance matching, which reduces signal reflection and ensures efficient power transfer. The stable 50Ω impedance further contributes to the antenna's reliable performance, resulting in a more stable and consistent 4G connection.

4. Convenient Installation: The GL - DY828 features a magnet - based installation method. This allows for easy and quick installation on metal surfaces, such as the roofs of vehicles or metal structures. It provides a hassle - free setup process, making it convenient for users who need to set up the antenna frequently or in different locations.

5. Environmentally Friendly and Durable: Being ROHS compliant, the antenna is environmentally friendly, meeting strict environmental standards. It can operate in a wide temperature range from - 40℃ to + 85℃ and a humidity range of 5 - 95%. This durability makes it suitable for various environmental conditions, whether it's extreme cold, hot weather, or high humidity environments.
