Considerations for Electromagnetic Radiation Protection in Vehicle-Mounted Frequency Interference Devices

Ensuring Safety Measures for Passengers and Drivers

Vehicle-mounted frequency interference devices are commonly used in vehicle modifications to disrupt radio frequency signals. However, concerns arise regarding the potential electromagnetic radiation emitted by these high-power RF transmission devices. This article addresses the importance of considering electromagnetic radiation protection measures for passengers and drivers when using vehicle-mounted frequency interference devices.

Reducing Electromagnetic Radiation Exposure:

It is understandable that customers express concerns about the potential health effects of prolonged exposure to high-intensity electromagnetic radiation emitted by vehicle-mounted frequency interference devices. These devices typically emit RF power in the range of several tens of watts per frequency band, resulting in significant electromagnetic radiation at close distances. However, the use of steel or other metal materials for the vehicle body in which the device is installed provides substantial attenuation and reflection of RF signals.

Protection Inside the Vehicle:

Passengers and drivers inside the vehicle, beneath the antenna, experience significantly reduced electromagnetic radiation intensity due to the shielding effect of the vehicle’s metal body. This protection is noticeably better than being outside the vehicle. The characteristics of steel or other metal materials used in the vehicle body result in significant attenuation and reflection of RF signals, ensuring a safer environment for individuals inside the vehicle.

Enhancing Electromagnetic Radiation Protection Measures:

To further strengthen electromagnetic radiation protection in vehicle-mounted frequency interference devices, several methods can be employed:

  1. Antenna Deployment System: During the structural modification of the vehicle, a metal base plate can be pre-installed to enhance the isolation between the antenna emission device and the vehicle interior, effectively reducing signal penetration.
  2. Electromagnetic Radiation Protective Clothing: All individuals involved in the use of the vehicle-mounted frequency interference device should be provided with a set of electromagnetic radiation protective clothing. This additional layer of protection minimizes direct exposure to electromagnetic radiation.
  3. Vehicle Window Shielding: As the vehicle body provides a certain level of radiation shielding, weak areas such as vehicle windows can be further protected. Applying radiation-resistant films to the windows or installing radiation-blocking curtains on the inside can effectively reduce electromagnetic radiation penetration.


While concerns about the potential health effects of electromagnetic radiation from vehicle-mounted frequency interference devices are valid, the use of metal materials in the vehicle body significantly reduces radiation exposure for passengers and drivers. Implementing additional protection measures, such as antenna deployment systems, electromagnetic radiation protective clothing, and window shielding, further enhances safety. By considering and implementing these measures, the use of vehicle-mounted frequency interference devices can be both effective and safe for all occupants.
