In recent years, the demand for vehicle-mounted frequency jammers has been greatly improved, especially in terms of high-power models, which are particularly favored by police departments. However, in the stages of vehicle modification and equipment integration during the equipment selection and delivery process, there will always be a topic that makes people particularly entangled: customers originate from the consideration of concealment when performing tasks, and strongly hope that the antenna on the vehicle can be inconspicuous , unassuming, and even better not to be seen or recognized by others. Then the question arises: Can the antenna of the car frequency jammer be installed directly inside the car for concealment?

The conventional construction plan is to install the antenna of the vehicle-mounted frequency jammer on the top of the vehicle. The advantages of this are obvious: the first advantage is that the height of the vehicle roof is used reasonably. When the vehicle-mounted antenna is erected on the roof, the antenna The emitted interference signal can obtain a larger signal coverage, and in the process of transmission to the surroundings, it can basically overcome the blocking effect of vehicles on other roads. The second advantage is that the installation space on the roof is relatively generous. Even if the number of antennas configured for the vehicle-mounted frequency jammer reaches more than 10, the space on the roof is sufficient to accommodate it. The third advantage is that the roof can also be equipped with an antenna lodging mechanism. When the equipment is not powered on, all the antennas can be stored lying down.

However, the disadvantage of installing the antenna on the roof is also obvious, that is, in the working state, several antennas erected on the roof will be very conspicuous, making the vehicle frequency jammer highly recognizable, and it is too easy for the outside world to see that this is A special vehicle for special operations. So its concealment is almost zero.

So if the car antenna is not installed on the roof, but all installed inside the car, is it feasible to do so? The answer is very clear: such an approach is extremely inadvisable. The reasons include three aspects: First, the carriage itself is composed of a relatively closed metal frame and metal sheets. This structural feature will interfere with the vehicle frequency jammer. The transmission of the signal produces a very large attenuation effect, which undoubtedly greatly reduces the interference performance of the interference device artificially. The second reason is that the antenna is installed in the car, and the height of the antenna from the ground is also reduced a lot. The reduction of the height will cause the interference signal to be easily blocked by surrounding vehicles or low objects. The third reason is that this kind of high-power vehicle-mounted frequency jammer and the high-power radio-frequency interference signal emitted by the antenna are close to the antenna. The intensity of its electromagnetic radiation is harmful to the body of the driver and passengers inside the compartment Health is extremely unfavorable.
