Research and development process of drone signal jammer blocker:

1. PCB assembly production: Design RF circuits based on the frequency bands that need to be disrupted. This includes component selection, schematic design, layout design, etc. This process takes 1 to 2 months.

2. Industrial design: Design the appearance of the jammer according to the requirements, such as whether it should be fixed or portable. Consider factors such as safety, stability, battery power supply, antenna placement, etc.

3. Testing: Testing is needed after the product is completed. It needs to be conducted in different scenarios, such as cloudy, sunny, rainy, or foggy weather conditions, and in both flat and mountainous areas, Based on the test results, the product will be improved and optimized.

In summary, a high-quality drone signal jammer needs a significant amount of research and development, as well as time investment.
