During this period, many high-power signal jammers have been purchased and installed on vehicles. In the process of installing high-power signal jammers on cars, all the equipment is hidden and not discovered. Therefore, the jammer antenna cannot be installed at the tail, which is not conducive to concealment and affects the appearance of the vehicle. So can the vehicle-mounted signal jammer install the antenna in the car?
First of all, from the most beneficial point of view, if the server, RF connection coaxial cable and multiple antennas of the vehicle-mounted signal jammer are all installed in the internal structure of the car, then, from the inside of the car, others will completely install what kind of machine is installed inside the car, and will not find out what kind of isolation effect the car has. Concealed installation and quality are very obvious!
First of all, we need to start from the most beneficial point of view. If the server, RF connection coaxial cable and multiple antennas of the vehicle-mounted signal jammer are installed in the car, then, from the inside of the car, others will completely install the vehicle-mounted signal jammer inside the car, which will generally not be discovered. Concealed installation and quality are very obvious!
When all 8 antennas of the vehicle-mounted signal jammer are installed in the car, the following problems will occur:
1. The signal, coverage and distance sent by the vehicle-mounted signal jammer through the antenna will be greatly reduced.
Mainly because the car body is mostly made of metal structures, metal structures and panels, there will be a great deviation in the transmission of wireless signals. At the same time, the car body is a relatively closed structure. After the radio frequency signal is sent out, there will be multiple reflections in the internal structure of the car body, which makes it difficult for the signal to be fully transmitted to the outside world and range. This part of the signal is destroyed in vain. At the same time, even if the antenna is erected in the car, it is definitely not as good as being installed on the ceiling. The different installation heights of the antennas will also lead to a reduction in the coverage radius.
2. The antenna of the high-power vehicle-mounted signal jammer for cell phone is installed in the car. Once it is started, the driver cannot stay in the car for a long time, mainly because the distance to the antenna is too close, and the signal is reflected back and forth in the car, and the electromagnetic radiation intensity formed may exceed the standard, which will inevitably have a negative impact on a person's health.
3. If the server equipment and antenna of the wireless vehicle-mounted signal jammer are all installed in the car, it will occupy too much space, because it should be considered that the antennas of each different frequency band must maintain a certain distance, so the back seat and trunk of a car will be occupied.
