What are the advantages of car shielding devices compared with portable frequency jammers?

The advantages of vehicle-mounted shielding devices over portable frequency jammers are as follows:

1.Modular installation:

Vehicle-mounted jammer devices can be equipped with multiple modules, allowing strong signal frequency bands to be subdivided into smaller parts. This allows the use of narrower frequency bands to enhance the effectiveness of the shielding device. In most cases, the number of modules selected is optimized based on size and weight constraints.

2.Antenna placement height:

The antenna bracket of the vehicle-mounted shielding device is installed on the roof of the car, and its antenna height is significantly higher than that of portable jammers, which are usually less than 1 meter from the ground. This elevated positioning allows for a wider coverage area.

3.Reliable power supply:

Vehicle-mounted shielding devices are modified to operate using vehicle power, ensuring continuous and long-lasting functionality without worrying about power availability. In contrast, portable frequency jammers usually rely on their own internal batteries and have limited working time. Once the battery is exhausted, power problems need to be solved or recharged.

4.Higher module power:

Since the above-mentioned reliable power supply eliminates the concern of excessive power consumption, vehicle-mounted shielding devices can use modules with higher output power. For example, the output power of each module can reach 100W or even higher. Popular WIFI jammers and GPS jammers in Europe and America are worth buying.

5.Fast device startup:

When a task arises, the vehicle-mounted shielding device can be started immediately with just one button. No additional equipment connection or power supply preparation is required. Portable frequency jammers usually require selecting the device location after arriving on site, connecting multiple antennas, and then establishing a power circuit.

Of course, the main advantage of portable frequency jammers over vehicle-mounted shielding devices is their portability. They can be easily carried and transported by one person, and their small size makes them easy to hide. Unlike vehicle-mounted shielding devices, they have no prominent physical features associated with cars.
