The exterior of the shield is a kind of outer antenna and a built-in antenna, and basically, the external antenna is out of the antenna, and it's out of the outside, so it's a little bit bigger than the built-in antenna; The external antenna is more stable because of the extended antenna. The shield can generally be divided into small power, medium power, high power, between 3W and 100W, and it is generally not recommended to use a large power signal shield, which can seriously interfere with the transmission of the base station signal and also have a certain degree of radiation to the human body.
