Choose a high-performance 4G GPS antenna
1、 Antenna performance
1.1 Gain value
Gain value is one of the important indicators to measure antenna performance, and the higher the value, the stronger the ability to receive signals. 4G GPS antennas with gain values above 5dBi have excellent signal reception capabilities and are suitable for areas with weak signals.
1.2 Impedance matching
Impedance matching refers to the degree to which the input impedance of the antenna matches the output impedance of the signal source. When the impedance matching between the antenna and the signal source is high, it can improve the transmission efficiency of the signal, thereby improving the reception effect of the antenna.
1.3 Bandwidth
Bandwidth refers to the range of signals that an antenna can receive within a certain frequency band. The wider the bandwidth, the wider the selection range of the antenna when receiving signals. When purchasing a 4G GPS antenna, it is important to choose an antenna with a wider bandwidth.
2、 Band adaptation
Due to the different 4G frequency bands in different regions, when purchasing a 4G GPS antenna, it is necessary to choose the appropriate 4G GPS antenna based on your region and the desired frequency band. At the same time, it is also important to note whether the antenna supports multi band coverage, so that it is not restricted when used in different regions.
3、 Installation method
3.1 Antenna Type
There are various types of 4G GPS antennas, such as car antennas, outdoor antennas, indoor antennas, etc. When purchasing, it is necessary to choose the appropriate antenna type based on different usage scenarios to ensure that the antenna's usage effect reaches its state.
3.2 Installation position
The installation position of the 4G GPS antenna has a significant impact on its reception effect. The higher the installation position of the 4G GPS antenna, the better the signal received. When installing the antenna, choose a high position and keep the antenna level.
Brand is also an important consideration when purchasing 4G GPS antennas. The quality and performance of well-known brands' products are guaranteed, and their after-sales service will also be more comprehensive. When choosing, you can choose well-known brands of 4G GPS antennas.
In summary, when choosing high-performance 4G GPS antennas, attention should be paid to antenna performance, frequency band adaptation, installation method, brand, and other aspects. Only by considering all these aspects comprehensively can we choose a 4G GPS antenna that meets our own needs and improve the effectiveness of use.
