The conference room signal shielding device with built-in antenna can not see the antenna from the outside at all, achieving 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, it will cause bumps accidentally, and it is easy to knock off the antenna, so that the machine can no longer be used, and continued use will cause the internal module of the conference room signal jammer to burn out. If the conference room signal shielding device 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 conference room signal shielding device.
