How to choose and install a 2g antenna?

1、 Purchase 2G antenna

1.1 Frequency range

The frequency range of 2G antennas is generally 800-960MHz, so it is necessary to pay attention to whether the antenna supports the 2G signal frequency band of the region when purchasing, otherwise it may cause unusable situations.

1.2 Gain value

Gain value refers to the ability of an antenna to transmit and receive signals. Generally speaking, the larger the gain value, the stronger the signal transmission ability of the antenna. However, excessively high gain values can also lead to signal interference and overload issues, so it is necessary to choose according to the actual situation.

1.3 Antenna Type

The types of 2G antennas include patch antennas, flexible antennas, Yagi antennas, etc. Different types of antennas are suitable for different scenarios. Patch antennas are generally used inside mobile phones, flexible antennas are suitable for curved scenes, and Yagi antennas are suitable for scenes with weak signals.

2、 Installing 2G antenna

2.1 Installation position

The installation position of the 2G antenna needs to be selected in a location that can receive signals, generally speaking, the signal is better at a high position. At the same time, attention should be paid to avoiding interference with other electronic devices, such as maintaining a certain distance from TV antennas, microwave ovens, and other devices.

2.2 Installation height

The installation height of a 2G antenna is related to the transmission range of the signal. Generally speaking, the higher the height, the wider the transmission range. However, excessive installation height can also lead to issues such as signal overload and interference, so it is necessary to choose according to the actual situation.

2.3 Installation method

The installation methods of 2G antennas include wall mounted, suction cup, pillar, and other methods, which need to be selected according to the actual situation. At the same time, it is necessary to pay attention to whether the installation method can firmly fix the antenna to avoid shaking and falling.

The selection and installation of 2G antennas is an important part of using 2G networks. The correct selection and installation method can improve the communication quality and stability of 2G networks. I hope this article can help readers better understand and use 2G antennas.
