How should the vehicle frequency jammer take protective measures against electromagnetic radiation?

When the vehicle frequency jammer completes the whole vehicle modification and the assembly and commissioning of the frequency jammer, some customers will ask such questions: in the future, when the vehicle frequency jammer equipment works normally, after all, this is a set of high-power RF transmitting device, which will inevitably have a certain intensity of electromagnetic radiation. So how should the electromagnetic radiation protection measures for drivers and passengers in the vehicle be considered?

The customer's concern is understandable. For a set of high-power vehicle frequency jammer, the RF power transmitted by the vehicle antenna at the top and each frequency band are at least tens of watts. There will indeed be large electromagnetic radiation at a close distance. If the drivers and passengers are in the environment of short-range and high-intensity electromagnetic radiation for a long time (for several consecutive hours), it will have an adverse impact on human health.

However, because the refitted vehicle used by the vehicle frequency jammer is made of steel plate or other metal materials, the characteristics of this material itself will have a great attenuation and reflection effect on the transmission of RF. The intensity of electromagnetic radiation received by drivers and passengers in the car under the antenna has been greatly reduced, and the protection effect of human body in the car will be significantly better than that outside the car (around the car).

From the perspective of strengthening the anti electromagnetic radiation protection measures of vehicle frequency jammer, there are usually several ways:

1. When the structure of the antenna lodging system on the roof is modified, the whole metal base plate is preset in advance to strengthen the isolation between the antenna transmitting device of vehicle frequency interference and the signal in the vehicle;

2. All drivers and passengers who participate in and use this set of vehicle frequency jammer shall be issued with a set of electromagnetic radiation protective clothing;

3. The main structure of the vehicle carrier used for refitting the vehicle frequency jammer is a metal structure, which has the function of certain radiation isolation. However, due to the existence of weak areas such as window glass, it is recommended to paste anti radiation film on the window glass or install anti radiation curtain on the inner side of the window when refitting the vehicle.
