In recent years, many public security special police departments have started to purchase and install vehicle-mounted frequency jammers. Typically, these customers provide an SUV chassis and then send the purchased frequency jamming equipment to a vehicle modification factory for installation and assembly. The goal is to create a qualified and satisfactory vehicle-mounted frequency jammer. However, during the process of designing the vehicle modification plan, there is often a question about which power supply option is the best, which becomes the first issue that customers must address. Due to the high power consumption of vehicle-mounted frequency jammers, it is generally required that the modified vehicle be able to provide at least 5KW of power output. In some cases, vehicle-mounted frequency jammers may require at least 10KW of power output due to the need for at least 24 communication interference modules to target various wireless signals. Relying on the vehicle’s own generator or battery will certainly not meet the power supply requirements.
Power Supply Options:
There are two main options for providing power to vehicle-mounted frequency jammers during vehicle modification. The first option is to choose a conventional gasoline or diesel generator. The biggest advantage of this approach is its low cost and affordability. The purchase cost of a gasoline or diesel generator can be as low as 10,000 to 20,000 yuan. However, this method also has significant drawbacks. It requires the creation of a separate compartment within the vehicle, as well as proper exhaust and ventilation measures. These types of generators produce significant noise, and the emitted fumes and exhaust gases need to be quickly expelled from the vehicle. Another drawback is that if the modified vehicle is used in a stationary state, such as during parking, and the onsite environment is windless, the fumes and exhaust gases will quickly accumulate around the vehicle, which will greatly affect the user experience of the vehicle-mounted frequency jammer.

The second option is to choose a power take-off (PTO) generator, which is installed next to the vehicle’s original engine and driven by a belt to generate electricity. The advantages of using this method are obvious: low noise, stable and reliable power output, and no additional fumes or exhaust gases generated. However, there are also drawbacks that may cause customers to hesitate. The purchase cost of a PTO generator is relatively high, with a set costing at least several hundred thousand yuan, and even as high as two to three million yuan. Another drawback is that not all vehicles can be used as the chassis for vehicle-mounted frequency jammers. This is because the availability of suitable space in the vehicle’s engine compartment for installing the PTO generator needs to be considered.
If we, as the manufacturer, are asked to provide a recommendation, our leading suggestion would be to choose the PTO generator as the power supply option for vehicle-mounted frequency jammers. Despite the higher procurement cost, the advantages of low noise, stable power output, and absence of additional fumes and exhaust gases make it the most suitable choice. However, it is important to carefully consider the specific requirements and limitations of each vehicle before making a final decision.
