824-896MHz 2dBi Terminal Antenna for Portable Communication Devices

Product Introduction

1.Precise Frequency Band Coverage: 

Optimized for the 824-896MHz frequency band, perfectly matching the uplink/downlink frequency range of mobile communication systems such as GSM 900MHz, providing a high-efficiency and stable signal transmission and reception foundation for related terminal equipment.

2.Omnidirectional Vertical Radiation: 

Employing vertical polarization, it achieves 360° omnidirectional uniform coverage in the horizontal plane. This means that regardless of how the terminal equipment rotates or moves, a good signal connection is maintained, eliminating the need for directional alignment, making installation and use extremely simple.

3.Compact and Lightweight, Easy to Integrate: 

With a total antenna length of 2000mm and a weight of only 0.04kg, it boasts a lightweight structure. With a standard SMA male connector, it can be easily screwed directly onto the external antenna ports of various communication terminals, test equipment, or modules, offering high integration.

4.Stable Electrical Performance: 

Voltage Standing Wave Ratio (VSWR) ≤2.0 indicates good matching with a 50-ohm feeder system, effectively transmitting RF energy and reducing reflection loss. A maximum power capacity of 50W ensures its durability and reliability in conventional applications.

5.A cost-effective, versatile solution: 

2dBi gain provides basic yet effective signal enhancement. With its simple design, reliable performance, and economical cost, this antenna is an ideal standard or replacement antenna choice for many mobile terminals, data acquisition devices, and automotive equipment operating in the 900MHz band.

Application Scenarios

GSM vehicle communication terminals

Portable test and measurement equipment

Industrial data acquisition terminals (DTU/RTU)

Wireless meter reading concentrators

Some Internet of Things (IoT) gateway devices

FAQ

Q: This antenna only has a 2dBi gain; won't the signal be weak?

A: 2dBi is typical for this type of omnidirectional whip antenna. It primarily provides basic omnidirectional coverage rather than long-range directional enhancement. For most short-to-medium distance terminal applications requiring omnidirectional communication (such as vehicle-mounted mobile devices, localized area coverage), this gain is sufficient and appropriate.

Q: Is it an indoor or outdoor antenna?

A: Based on its structure (long whip shape) and parameters, it can be used both indoors and outdoors. However, please note that the product documentation does not explicitly state a waterproof rating. If used outdoors, it is recommended to assess the installation environment or take appropriate protective measures.

Q: Can it be directly connected to my device?

A: This depends on your device's interface. The GL800LA comes standard with an SMA male connector. Please confirm that your device's antenna port is an SMA female connector (most common); otherwise, a corresponding adapter is required.

Q: What does its 72MHz bandwidth mean?

A: This means that the antenna maintains good performance (e.g., VSWR ≤ 2.0) within the 72MHz wide frequency range of 824-896MHz. This is sufficient to cover the designated frequency bands of systems such as GSM 900MHz, ensuring signal stability within the operating frequency band.

Q: What are the benefits of vertical polarization?

A: Most terrestrial mobile communication systems (such as public walkie-talkies and cellular networks) use vertically polarized waves. Using a vertically polarized antenna maximizes the received and transmitted signal energy, reduces losses caused by polarization mismatch, and thus improves communication efficiency.

Q: Can it be used for transmission? What is the power?

A: Yes. It supports a maximum input power of 50W, which fully meets the transmission power requirements of most terminal devices (usually below 2W), leaving ample margin and ensuring safety and reliability.
