When choosing a mobile phone signal jammer, should you choose an external antenna or an internal antenna? What is the difference?
Nowadays, there are often some uncertainties in internal company meetings. Often, some simultaneous mobile phone rings or phone calls will disrupt the leaders' meetings. Therefore, in order to avoid being affected by external factors during meetings and to avoid the leakage of meeting topics, many companies have installed cell phone signal jammers to help companies solve this problem. This is also a wise choice for many companies.
When choosing a mobile phone signal jammer to be used in a conference room or office, you need to understand what types of equipment and types are available on the market today. So we spent a few days to learn that the mobile phone signal jammers on the market today are mainly divided into internal antennas and external antennas. So is the mobile phone signal jammer in the conference room an internal antenna or an external antenna?
This depends on your needs. You can choose a mobile phone signal jammer with an external antenna based on the actual area size. This type of mobile phone signal jammer with an external antenna is generally very cheap. Let's not talk about the quality and processing technology. Some mobile phone signal jammers with external antennas have antennas of different lengths, which is definitely not beautiful. In addition, the radiator fans of some mobile phone signal jammers are exposed to the outside, which will also cause some noise, which will affect the order of the meeting room.
For mobile phone signal jammers with built-in antennas, the external antenna is absolutely invisible, which achieves the ultimate unified appearance, and the built-in antenna is a kind of protection for the antenna. If the external antenna needs to be moved and used, it may be knocked off by accident, so that the device can no longer be used, and normal use will also cause the internal structure control module of the mobile phone signal jammer to burn out. If the mobile phone signal jammer with a built-in antenna needs to be moved, it can directly grasp the concave groove door handle on the back of the device, which is simple and practical. Even if it is slightly bumped, the internal structure antenna will not fall off, which can ensure the normal operation of the full-band jammer.
In general, when buying a cell phone signal jammer, it is best to choose one with a built-in antenna.
