Everyone needs different jamming frequencies, jamming environments, and the types of jammers they like, so everyone's required jammer solutions will also be different. Therefore, we will recommend that customers choose a jammer that meets all their needs, not necessarily the most expensive jammer is the most suitable for you.

There is no one-size-fits-all jammer, only one that fits the user's needs and environment.

First of all, you need to evaluate or know the interference frequency and power of the electronic equipment that needs to be shielded, and also evaluate how much coverage jammers to choose. Knowing these points, it is a good choice of jammer

Regarding frequency Don't choose a frequency that exceeds the desired interference frequency, although it is more powerful, it may increase your budget
Regarding power: it is better to choose a power larger than the power of the electronic device that needs to be jammed, because if the power of the jammer is less than the power of the signal transmitted by the electronic device, the jammer may not be able to fully jam, or even work.
Regarding the interference range: Because the interference range is too small, it may not meet your interference needs, and the interference may cause others and increase your budget.
Regarding the type of jammer: it is necessary to evaluate which is more convenient for portable or desktop jammers. Portable jammers, as the name suggests, are easy to carry, suitable for outdoor use and frequently change the location of use, but cannot work continuously for a long time, and their stability is inferior to desktop jammers. The jammer can work for a long time, and the performance of the jamming signal is stable, but it is inconvenient to move. It is recommended to weigh the advantages and disadvantages of both before making a choice.
