Can the antenna of the vehicle-mounted mobile phone signal jammer be installed in the car to be hidden?

In recent years, the demand for vehicle-mounted mobile phone signal jammers has increased significantly, especially high-power models, especially in the police force. However, during the equipment selection and delivery process, there is a general concern about installing inconspicuous antennas in vehicles for covert operations. Here comes the question: Can the antenna of the vehicle-mounted mobile phone signal jammer be hidden by installing it in the car?

The traditional method is to install the antenna of the vehicle-mounted cell phone jammer on the roof. This method has obvious advantages. First, it optimizes the utilization of the roof height. When the antenna is placed on the roof, the interference signal it transmits can achieve a wider coverage and overcome the obstacles of other vehicles on the adjacent road. Second, the roof provides ample installation space and can even accommodate more than 10 antennas of mobile phone signal jammers. Third, a tilting mechanism can be adopted, and the antenna can be folded up and stored when the device is not in use.

However, the disadvantage of the roof antenna installation is that it is too conspicuous. The upright antenna makes the vehicle-mounted mobile phone signal jammer very conspicuous, thereby compromising its concealment. This lack of concealment is undesirable, especially for vehicles engaged in special operations.

Considering the possibility of mounting the antenna completely inside the vehicle cabin, this approach is highly impractical for a number of reasons. First, the enclosed metal frame and panels of the vehicle act as a shield, greatly attenuating the interference signal emitted by the jammer. This reduces the jamming performance of the device and hinders its effectiveness. Second, by mounting the antenna inside the vehicle, its height from the ground is greatly reduced. This reduction in height makes the jammer signal more susceptible to being blocked by surrounding vehicles or low objects. Finally, the high-powered RF jammer signals emitted by the vehicle-mounted mobile phone signal jammer will generate electromagnetic radiation near the antenna. This radiation poses a significant risk to the health of the driver and passengers in the vehicle.

In summary, installing antennas hidden inside vehicles is not feasible due to signal attenuation, hindered susceptibility, and potential health hazards associated with electromagnetic radiation.
