High-gain 5dBi 3G Magnet Antenna 3 Magentic Base GL-DY825

Product Introduction

1. Wide Frequency Coverage: The GL - DYG825 3G Magnet Antenna operates across the 824 - 960/1710 - 2170MHz frequency bands. This wide range makes it suitable for multiple 3G networks, ensuring compatibility with different carriers and regions. It can support various communication services within these frequency ranges, providing users with reliable connectivity in different network environments.

2. Good Gain Performance: With a gain of 5dBi, the antenna effectively boosts signal strength. A higher gain enhances signal reception and transmission, which is crucial for extending the communication range. Whether in a remote area or an area with weak network coverage, this antenna can improve the quality of 3G connections.

3. Stable Electrical Characteristics: It has a VSWR of less than 1.5 and a normal impedance of 50Ω. The low VSWR indicates excellent impedance matching, reducing signal reflection and ensuring efficient power transfer. The stable 50Ω impedance further contributes to the antenna's reliable performance, resulting in a more stable and consistent 3G connection.

4. Convenient Installation: The GL - DYG825 features a magnetic installation method. This allows for easy and quick attachment to metal surfaces, such as vehicle roofs or metal structures. It provides a hassle - free setup process, making it convenient for users who need to install 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 withstand vibrations (10 to 55Hz with 1.5mm amplitude for 2 hours) and 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.

Application scenarios

• Vehicle-mounted 3G/4G communication systems.

• Remote IoT sensors in agriculture or logistics.

• Industrial machinery requiring stable cellular connectivity.

• Temporary outdoor setups like construction sites or event monitoring.
