The police wireless signal jammer is mainly used for auxiliary equipment used by the police in dealing with some special tasks, such as collective mass events, temporary communication control, remote-control bomb removal, low-speed small UAV defense, suspect capture and other tasks.

The police wireless signal jammer is generally portable and can be designed as a trailer or backpack. Under normal circumstances, the police wireless signal jammer is equipped with omni-directional antenna. The advantages of the Police Wireless Signal Jammer equipped with omni-directional antenna are as follows:

1. It is easy to carry. The omnidirectional antenna is basically a FRP shell. When carrying, just put the antenna into the storage bag. It is best to be equipped with a special storage aviation box for the antenna, which takes up a small space and can also avoid bumping between antennas.

2. The disassembly and assembly is fast. When the police arrive at the task site, just screw down the omni-directional antenna by matching the frequency band of the omni-directional antenna with the frequency band interface of the police jammer. It is also very convenient to disassemble. Screw down the antenna and put it into the storage bag. It is especially applicable to the application scenarios when the police handle the above tasks.

If the police wireless signal jammer is equipped with directional antenna, it will be too inconvenient. The directional antenna is relatively large, inconvenient to carry and occupies a large space. It is necessary to carry not only the directional antenna, but also the mounting bracket of the directional antenna, which is also a problem to store. During disassembly and assembly, the directional antenna needs to be installed on the antenna support first, and then connected to the host of the Police Wireless Signal Jammer through the feeder. When the police deal with the above tasks, the preparation time is relatively long, and the operation is relatively cumbersome. Therefore, the directional antenna is not suitable for the police to use when dealing with outdoor tasks.

The directional antenna is suitable for use in some fixed places. It can be used normally only by erecting the antenna and adjusting the coverage angle before installing the equipment and antenna, and fastening the feeder connection between the antenna and the equipment host.
