3g Mobile Antenna Purchase Guide
3G mobile antenna purchase guide, how to choose the suitable mobile antenna for oneself
In the 3G era, mobile phones have become an indispensable part of our lives. However, with the instability of network signals, mobile phone signals also become unreliable. At this point, mobile phone antennas have become a powerful tool for solving signal problems. But how to choose a suitable phone antenna for oneself? This article will explain how to choose a suitable mobile phone antenna from the following aspects
1、 Antenna type
2、 Antenna frequency
3、 Antenna gain
4、 Antenna directionality
5、 Antenna brand
1、 Antenna type
At present, mobile phone antennas in the market are mainly divided into two types: internal antennas and external antennas. The built-in antenna refers to the internal antenna of a mobile phone, while the external antenna requires an external antenna.
The advantage of a built-in antenna is that it is easy to carry and does not require additional installation. However, due to the limitations of the phone itself, its signal enhancement effect is not very good. External antennas can better enhance the signal, but require additional installation, which brings inconvenience.
Therefore, when choosing an antenna type, it is necessary to choose according to your specific needs and usage scenarios.
2、 Antenna frequency
Antenna frequency refers to the frequency range supported by the antenna. The antenna needs to be selected based on the frequency range supported by the phone. If the selected antenna frequency range does not match the frequency range supported by the phone, the antenna will not function properly and may even affect the communication effect of the phone.
3、 Antenna gain
Antenna gain refers to the signal strength that an antenna can enhance when receiving a signal. You need to choose the antenna gain based on your signal environment. If the signal environment is poor, it is necessary to choose a higher antenna gain in order to receive the signal better.
However, the higher the antenna gain, the better. If the selected antenna gain is too high, it may cause signal interference and even affect surrounding communication equipment.
4、 Antenna directionality
Antenna directionality refers to the receiving range of the antenna when receiving signals. You need to choose the antenna directionality based on your own usage scenario. If you need to receive signals in a relatively fixed direction, you need to choose an antenna with corresponding directionality.
5、 Antenna brand
Brand is also a factor to consider. Choosing a well-known brand of antenna can ensure the quality and performance of the antenna, and avoid affecting communication performance due to poor antenna quality.
Choosing a suitable phone antenna for oneself needs to consider factors such as antenna type, antenna frequency, antenna gain, antenna directionality, and antenna brand. Only by selecting the appropriate phone antenna according to one's own usage needs can we better solve signal problems and improve communication efficiency.
