Difference between external antenna and internal antenna of desktop jammer
In order not to be disturbed by other factors during the meeting and to prevent the disclosure of meeting contents, the use of desktop jammer is a correct choice.
The jammer suitable for use in the conference room is mainly divided into built-in antenna and external antenna in the market. So the jammer in the conference room should choose built-in antenna or external antenna.
For smaller conference rooms, you can choose the desktop jammer with external antenna. The price of this jammer with external antenna is often relatively low. Let's leave aside the quality and technology for the time being. The antennas of some jammers with external antenna are even of different lengths, which will certainly affect the beauty. Moreover, the cooling fan of some jammers is exposed outside, and there will be some noise, which will affect the order of the conference room.
The desktop jammer with built-in antenna can't see the antenna from the outside, so it has a unified appearance, and the built-in antenna is also a kind of protection for the antenna. If the external antenna needs to be transferred for use, it will bump and fall off easily, so that the machine can no longer be used. If it continues to be used, the internal module of the jammer will be burned out. If the jammer with built-in antenna needs to be transferred, it can directly grasp the groove handle on the back of the machine, which is simple and convenient. Even if there is a slight bump, it will not cause the internal antenna to fall off, which can ensure the normal use of the desktop jammer.
To sum up, it is recommended to choose the jammer with built-in antenna when purchasing the desktop jammer.
