Because of the outwardly extending antennas, The external antenna is more stable. The general power range is 3W-480W. Mobile jammers can generally be divided into low-power, medium-power, and high-power. The power is between 3W-100W. It is generally not recommended to use high-power mobile jammers, which will seriously interfere with the base station signal transmission. ,
