There are many brands of jammers on the market, with good or bad quality. How to choose before purchasing? How can we buy cost-effective products, on-site interference effect and satisfactory equipment.

                  

1. To select a manufacturer, you first need to understand the interference parameters and materials of high power jammer. In terms of after-sales service, whether the product warranty time can be, and whether the high power jammer can be returned to the factory for maintenance.
2. After selecting the manufacturer, you can tell the manufacturer your needs. It is recommended to meet your needs. You can also visit the site as required, or carry a prototype of high power jammer for on-site test. After the field investigation, the manufacturer can plan the machine installation layout to maximize the interference effect.
3. Choose the one with low price and poor quality. Some brands have low prices. The selected electronic components are second-hand. At the beginning, the interference effect is very good. For a long time, the effect of the jammer is certainly not as good as that of the electronic components. The shielding effect is good. The low-cost jammer may not satisfy you after sales. For long-term consideration, we can choose the upgradeable high power jammer and reserve the position of the upgraded module. If the later interference effect is not good, we can add the module in the equipment to enhance the interference effect.
