The full-screen signal jammer is mainly used in special places where Internet access is prohibited. It is often used in concealed mission environments such as military bomb disposal, hunting down criminal suspects, protecting key leaders, and protecting transport teams. The shielding vehicle consists of a complete set of system software, including a high-power DDS control module, a microwave radio frequency omnidirectional antenna, a coaxial cable, a power supply system, etc.
When installing the full-screen signal jammer control module, the roof wireless antenna needs to be raised. The full-screen signal jammer uses an omnidirectional antenna. When the wireless antenna is perpendicular to the ground, the shielding effect is best.

Since the full-screen Cell Phone Jammer relies on power generation, there is enough power to drive the entire device when driving at high speeds. But when the vehicle stops, the idle speed of the vehicle must be increased to ensure that there is enough power output to ensure the normal operation of the shielding system.
To prevent signal interference, it is recommended to lower the wireless antenna when the vehicle is not in use for a long time. However, this step is not necessary during normal operation of the vehicle. It is also important to charge the power compensation battery regularly when the vehicle is not in use for a long time. The battery can be charged by simply starting the vehicle and activating the power generation capacity.
