Product Introduction
Single - frequency Precision：Designed specifically for the 868MHz frequency, the GL822 - 868 offers focused performance. This single - frequency operation allows it to optimize its capabilities for devices operating at 868MHz, such as LoRa - based sensors and wireless modules. It ensures efficient signal transmission and reception within this particular frequency band.
Decent Signal Boost：With a gain of 3 dBi, the antenna effectively enhances the 868MHz signal. This gain helps to extend the communication range of 868MHz - enabled devices, reducing the likelihood of signal dropouts. It is especially useful in areas with weak signals or when reliable long - range communication is required.
Low VSWR and Standard Impedance：Featuring a VSWR of less than 1.5 and a normal impedance of 50Ω, the GL822 - 868 ensures efficient power transfer. A low VSWR minimizes signal reflection, meaning more of the transmitted power is used for signal radiation. The 50 - ohm impedance is a standard in the industry, facilitating easy integration with other components in a wireless system.
Magnetic Mounting Convenience：The magnetic mounting method of the GL822 - 868 provides great convenience. It can be quickly and easily attached to any metal surface, such as a vehicle's body, a metal pole, or a metal - cased device. This allows for flexible placement to optimize signal reception, and the magnetic base provides a secure hold even in vibrating environments.
Environmentally Friendly and Durable：Being ROHS compliant, the antenna is environmentally friendly. It can also operate within a wide temperature range of - 40°C to + 85°C and a humidity range of 5% - 95%. Additionally, it can withstand vibrations in the range of 10 to 55Hz with a 1.5mm amplitude for 2 hours, making it suitable for use in various harsh environmental conditions.
Application scenarios
Fleet Tracking: Installs quickly on trucks, buses, or construction vehicles for GPS/telematics systems.
Temporary IoT Deployments: Ideal for pop-up sensor networks in agriculture, logistics, or disaster response.
Industrial Equipment Monitoring: Attaches to machinery in factories or warehouses for real-time data transmission.
Outdoor Wireless Networks: Provides reliable connectivity for remote weather stations or surveillance systems.
FAQ
Q:Can this antenna be reused on different surfaces?
A:Yes, the magnetic base allows easy removal and reattachment to any metal surface.
Q:Is the cable waterproof?
A:The RG174 cable is durable, but we recommend using a waterproof SMA connector cover for outdoor exposure.
Q:What devices is this antenna compatible with?
A:It works with any 868MHz LoRa, IoT, or telemetry device using an SMA female connector.
Q:Does it require a ground plane?
A:No, the magnetic base itself acts as a sufficient ground plane for optimal performance.
Q:Is the antenna suitable for high-vibration environments?
A:Yes, it’s tested to withstand vibrations (10–55Hz), making it ideal for vehicles or machinery.
Q:What is the warranty period?
A:The antenna comes with a 2-year warranty against manufacturing defects.
