The difference between the external antenna and the internal antenna of the full-band jammer

In order not to be disturbed by other factors during the meeting and to prevent the content of the meeting from being leaked, it is a correct choice to use a full-band jammer.

The full-band jammers suitable for use in conference rooms are mainly divided into built-in antennas and external antennas on the market. Then, the full-band cell phone jammer for conference rooms should choose built-in antennas or external antennas.
For smaller conference rooms, you can choose a full-band jammer with an external antenna. The price of this kind of full-band jammer with an external antenna is often relatively low. Let’s not talk about the quality and workmanship. The antennas of the jammers are even different in length, which will definitely affect the appearance, and the cooling fans of some full-band jammers are exposed outside, and there will be noise, which will affect the order of the conference room.

The full-band jammer with a built-in antenna cannot see the antenna from the outside at all, achieving a uniform appearance, and the built-in antenna is also a kind of protection for the antenna. If the external antenna needs to be transferred to use, it is easy to knock off the antenna due to accidental bumping, so that the machine can no longer be used, and the internal module of the full-band jammer will burn out if it continues to be used. If the full-band jammer with built-in antenna needs to be transferred, you can directly grab the groove handle on the back of the machine, which is simple and convenient. Even if there is a slight bump, the internal antenna will not fall off, which can ensure the normal use of the full-band jammer.

To sum up, when purchasing a full-band jammer, it is recommended to choose a full-band jammer with a built-in antenna.
